I don't fully understand clean pond water filtration that you show. But I'm going to look through your videos until I learn so that I can duplicate it. I appreciate you so very much ☺️
Ammonia toxic to fish. Beneficial bacteria break down ammonia into nitrate (still harmful) Other beneficial bacteria break down nitrate into nitrite (less harmful and consumed by plants) Plants eat the nitrite before the algae has a chance to (prevents green water) Gravel/rock traps particulates and provides a substrate for beneficial bacteria to grow
Plants do alot of filtering. It's the only way to keep nitrate down without alot of work. Yeah it may only filter a small amount of amonia and nitrite too but plants are there to help keep the system balanced. Super awesome video the detail you have in here is awesome.
When I had a similar set up it also gave crystal clear water you have great videos on this subject. The only thing I added to mine was a settling tank before it went back into the pond full of Daphnea that would eat up all the green water if there was any that developed in the high summer. so that's my only tip to anyone out there. Daphnea will eat your green water and the daphnea that trips into the flow are a bonus for the fish. Keep up the great work !
Thank you very much! One of the best videos that better explains everything. Everyone is trying to sell you onto an ides that you need better filters. You have just opened up my eyes to a natural eco-friendly way.
Thanks for sharing this information, I’m retired and living on a small budget but I still want to enjoy the good things in life so finding out how to do them on the cheap is a huge bonus, I’m going to build a system in about a year because I’m doing a major rebuild of my house and the Koi pond is still a ways off, you videos are an inspiration to me, thank you for sharing your knowledge.
Thanks Nancy. You watch it as many times as you need 😉. I’ve got lots of other videos to scroll through if there is something in particular that is confusing 👍
Love the simple concepts, I put a DIY bog/gravel filter on my Koi pond and use it to grow plants and cress and the water is incredible, highly recommend adding this kind of thing to any pond, Great vid 👍👍

Thanks so much for making the videos and sharing on your channel. They are super informative for a total novice like myself, and i'm totally inspired now to build a pond and bog filter to go with it, all in my backyard.
Thank you so much for the info! We just started a "take care of the koi pond" club at school and our pond is so murky! You can barely see the beautiful little fish unless they're extremely close to the surface.
Impressive! I really enjoy this kind of stuff. Do you have any DIY tricks for eradicating string algae? I have a 750 gallon with skimmer & biofalls filter that contains 2 big net bags of bioballs and 2 thick plastic mesh pads to strain the waste and grow the beneficial bacteria. Just did a complete clean out of the pond less than a month ago. A high pressure water sprayer was used to clean all the rock & substrate at the bottom surface of the pond. But for so much string algae forming already... 🤔 Would appreciate any advice you may have.
@@Ozponds Fantastic! That's exactly what I was looking for since I don't have any snails that would be harmed. I'll watch your video so I can make an educated decision if I want to try this chemical treatment. I don't want to damage my water lilies or pond plants.

Nice video. Pretty ponds. Do you ever put overflow drains in? I have one in mine and it has saved my little pond a time or two when plants over grow and clog the regular drain pipe. I notice it because it makes a harsher noise draining. Would like to hear your opinion on pumps and which ones have worked the best for you.
In the bog filters I oversize the outflow pipe to prevent clogging. In the small systems like the wine barrel I have a guard around the overflow pipe. This prevents roots and gravel clogging it. To protect the fish if it ever overflowed I keep the pumps off the bottom of the pond. In the big ponds the pumps are housed in the skimmers so the pond can only really go down about 15cm (6in). In the small ponds I keep the 15cm off the pond floor, that way there would always be water for the fish. I will do another video on pond pumps. I prefer low volt models as the can be extended long distances without the need for an electrician and they are safer if there was a fault.
Hiya Kev, firstly, thanks for the content. I'm a newish pond owner and found most solutions to my problems through scrolling through your videos. Absolutely love your setup mate. Question, and it's possibly been answered in these comments but it's 2 years old and there's 199 comments!!! Where can I get or what material do I need to make those pipe looking structures you have sitting under your pump there please mate? Cheers and thanks again Steve
They are a type of aquaculture media. I got them as part of an aquaponic system I purchased off an old fella. I’ll other place I’ve ever seen them is Ali express.
Great video. Does the bog absolutely need the clean out pipe and valve? I understand that’s better but it would be a lot easier to build the bog without one. Thanks
It serves no function except for cleaning. The bog will still function perfectly fine. You’ll just need to manually remove everything when it becomes ineffective or clogged.
Nice video, thank you. A question: what is that plant that you have submerged quite some way above its crown? Sorry for being vague. It appears at least a couple times in this video. Thanks.
I’m not sure which one your referring to, but I’m sure you’ll find it in this video- DIY Ponds and DIY gardens | Plants I like to use th-cam.com/video/PksUcrwLtPI/w-d-xo.html
I feel like this would put some back pressure on the pump as it has to pump the water down and then push it all the way up. Is that true? And if you turn the pump off, some water will try and escape through that inlet pipe
I’d say it does but it mustn’t be much. It doesn’t seem to decrease the flow that I expect at the head height. I’ve also not had a pump fail on me yet (touch wood). I’m running quite a few ponds using these filters.
One question… i have aprox.. 7000liter pond… how big my filter should be… pump should be .. let’s say 8000liter per hour? :) You help me alot.. thanks!
If it was me I’d do a minimum 700 litre bog filter, pump approx 4200 litres moving through the bog. Other option a smaller high flow filter but move more water say 15-20,000 litres per hour.
@@Ozponds i was thinking to pump water from pond… in to the 200liter barrel.. what would be filter with rocks and this stuff.. then from filter into aprox 1000liter bog filter and then back into the pond… hope you understant what am i trying to explain 😊
Thanks Rob. I’ll make a video 👍. I prefer to use smaller aquatic plants, things that don’t have an invasive root system. I don’t want to block the flow of water also 50% of the plant growth should be removed every 12 months (roots and all). So anything that’s too vigorous can become a problem.
What type of pump would you use on your sketch and where would you position it in the pond? You mentioned debris accumulating at the bottom of the filter but in aquariums I usually keep debris from getting into the pump
I’m not sure what sketch that was (it’s an old vid) but I always use a submersible pond pump. I prefer the pump be housed in a skimmer or intake bay. That acts as a pre filter and prevents large stuff being sucked into the pump. It also delivers oxygen rich water to the filter. Really fine material will pass through the pump and accumulate in the filter. These filters are only being flushed once a year.
So for a 200,000 gallon pond I would need a 20000 gallon tub for a filter? I have a 180 gallon plastic tote and was planning on using that? Is that a no go? It is for koi fish and plan on stocking well but not overstocked.. thanks a bunch man awesome content 🙌
If you wanted to go the bog filter route, yes you would try and size at 10%.Of course you wouldn’t look for a container that size you would build a seperate filter pond. But that pond you are building is massive!! Is it receiving an inflow of water? If fresh water is constantly coming in filtration may be unnecessary. Another option is going a smaller filter but with a much higher flow. I think next week the waterfall filter video comes out. They filter the water with a smaller footprint but a bigger pump. The filter I built is too tiny for you but the principle can be scaled up. I hope that is helpful 👍
Enjoying your videos, thanks for sharing. Was that hydroton in for your bio filter? Looked like it, thanks probably will use it here when I get to that point.
Thanks I’m glad you’re enjoying the vids. The media in the bio filter was aquaponic clay balls. I think hydroton is the same or similar? It’s not a product we have in Australia but I remember a UK viewer mentioned it as a byproduct of pottery or clay businesses. If that’s the case I’m sure it will work great 👍
I have had green water issues in the past, but adding a bog filter has always solved them. I’m intrigued by fresh water mussels, but have been told they breed prolifically so I haven’t added them to any of my ponds yet. As I build more ponds I might experiment. Have you kept them? If so what has your experience been?
@@Ozponds i've kept them inside in tropical tanks. Had bad green water in my shrimp +baby guppy grow out tank, so popped two in there. They took it from pea soup to slightly stained in a few days and crystal clear in a little over a week., after that the plants took up the slack and haven't had an issue since. Thinking of getting some green water or a little wine barrel pond going in outside just to keep the buggers fed now! (rental house, so can't dig in) I hadn't heard they're prolific breeders, but apparently part of their lifecycle is piggy backing on fish gills. Think that's what puts people off.
God, it's great. Almost like mine but unfortunately, my lake had crystal clear water for a week, then it started to lose its potential. my mistake is that I did not provide a channel for meat water. had a way to be cleaned? or do I have to start all over again?
Great video! I have an issue. My bog filter system may have worked too well and I may have planted the wrong type of plants in it (alocasias) and after a year the tiny plants I planted are jurassic park sized. They are cemented in the container in one massive dense root ball and the water has stopped flowing from the cutout spillway. My system is a ~1 foot deep ~20 gallon premolded polythene pond liner with built in spillway cut out to which I added a bottom fed pvc pipe grid with holes drilled on the underside of the pipes. No separation between the layers and no drain. There seems to be no easy way to regain water flow. Any suggestions please?
Sorry you’re stuck. It’s a complete rebuild. If you watch my vids you’ll see I always recommended shallow rooted plants that can easily be thinned out. Good luck it’s no fun undoing all your hard work 😞
@@Ozponds Wow! Thanks for the quick response. I had a feeling that there's no easy way out of this. It's been amazing to see the big grow so quickly, We're going to miss the jungle it has become. Thanks for the content and response. Cheers
Is there a reason I see a lot of designs have the water pipe do a 90 degree turn down before releasing the water in the percolator? Can you just do a direct horizontal pipe line from your pump to the percolator?
The reason for me is that it means I don’t need to create another water proof hole in the filter. By coming in over the top I can also add in a breather pipe so that the filter doesn’t siphon empty if the pump stops. You can run it in horizontally if you want just make sure you have a way to prevent it siphoning if the pump shuts off. Hope that helps 👍
I keep wondering how many hours per day your pumps are running water through the filter? Probably depending on the time of the year?! Are you using solar pumps?
Im building a small 2ft wide by 4ft long pond 8 inches deep. I want to put a mini bog filter for it. If the clean out drain is below ground, how can i pump the junk out on a mini bog filter?
@@Ozponds God idea, thanks! I have some land I will be moving to in a couple of years. I'm planning on a larger pond with a full size in ground bog filter. Can hardly wait!
need help have pond one air pump fitting 18mm I need to adapt to 8mm air pipe any ideas? The pump came with a rubber tube that is about 18mm but can not seem to find a fitting for my large air stone that has a 8mm pipe.8
Thank you. Great Video. I understand how to build it. It is a simple, but smart design. I'm not too smart, so I have a question. Where is the water coming from for the inlet in the sketch you had in the video? Do I let water naturally fill it or do I have one of my pumps pushing water through it? Thanks for any help you can give?
Thanks mate 👍. You have e one of the pumps running water into the filter. Then so long as the outlet is higher than the pond water you let gravity put the clean water back into the pond. Hope that helps 👍
Can the flow rate be too much for the bog filter as I may have gotten a bigger pump than what my volume of the bog is, I am having a fast flow. My pond is almost a week old and I have algae, will it clear up in time to come
The flow rate can definitely be to much for a bog. You want a slow flow up through the bog. You can have as much water as you like flow over the top. If your pond is only a week old you are going to have algae. It’s can take ages for a pond to mature.
Either a bog filter at around 20% pond volume. Pump size around the volume of pond per hour. You could build a waterfall style filter moving up to 4X pond volume per hour. That would help. You’re also probably a bit overstocked with fish. Good luck 🤞
Great vids, would this same logic apply for a pond/pool specifically for ducks? I've got six and want to setup a filter for their pool, instead of just draining it.
Yes it would. Although I’d imagine it needs to be quite big. If you imagine the biological load of a duck compared to a fish. They produce more waste, drop feathers and will bring in all kinds of dirt and other debris. The ducks currently think I built my dream pond for them 😬
@@Ozponds I think I am going to try a double filter sort of thing, where the bulk waste/silt as well as feathers gets filtered out first sort of like a skim? and then the that water gets filtered off to an actual filter container, with the intention that cleaning it out would be easier.
@@Ozponds Do you think a swirl/vortex filter outputting to a biological filter would be sufficient? I had thought about getting a 14gallon barrel and doing a swirl filter at the bottom, with an enclosure around the input to act as a skimmer, then some sort of modular biofilter at the top, then purging the waste with an output at the bottom, and pulling out the biofilter to clean the skimmer enclosure when needed, but i'm not certain that the water wont be slow enough when traveling through the biofilter. The benefit though to breaking it down to two separate filters however would be being able to use the nitrate rich water from the vortex filter for the garden, before it passes through the biofilter.
@@Ozponds thank you so much for the reply, much appreciated 👍😊 I’ve had garden ornaments that I didn’t realise needed to be sealed and they started deteriorating due to being exposed to the elements so I didn’t want the same happening to the urn I’m intending to use as you have. I also didn’t want to accidentally poison the fish by using the regular pot sealers you get from Bunnings etc 😉 thanks again
Hi I have made a diy filter but struggle to get my water clear my filter contain stones big to medium to gravel there is no debris in the water only the green color is my concern. Can you give me advice what will clear up this green water? I have x3 gold fish inside
@@Ozponds Thanks for the quick respond and that leads to 1 more question. How many gallon per min/hr pump do you use for the pod filter and can I use 1 pump with a splitter for 2 or more pods? Thanks,
It depends on the size of the filter how many gallons. If you haven’t already look at my flow rate for bog filter video, that should help you work that out. Just remember if you are going to split the flow to multiple filters or ponds increase the flow rate. This is where low volt adjustable pumps can be very useful. Hope that helps 👍
I have just purchased a pressure filter for my pond which I set up 4 days ago and its gone murky already (any advice on that would be great). My question is can I run my pond water through that, then into a home made filter like yours and then back into the pond?? I just don't want to not use the pressure filter as it wasn't cheap
I don’t use pressure filters. But yes you could run the water through the pressure filter and then into a bog or high flow filter like the ones I make. But I’m not sure why you would, the pressure filter needs regular maintenance.
How do you mean regular maintenance, regular cleaning?? I mainly purchased it as it was supposed to eliminate that as it has a handle that you pull up and push down which cleans the sponge filter as you move the handle, turn the valve so the dirty water doesn't go back into the pond. I've always made my own gravity filters but thought the pressure might be better as I was always cleaning the home made filters I made, maybe I should of researched more and made a better one
Yeap. They sound good that’s marketing 👍. The sponges usually get blocked quicker than you’d think. Then a pipe pops off because everything is under pressure. There’s not enough media for biological processes so they usually include a UV light to prevent the water turning green. But remember I’m biased! I like diy. I hope your one is maintenance free and keeps your water nice and clean 👍
I have a whater mirror (large bird bath), and my pump turns on normally but get suuuper weak within a few minutes.... it has a external filter so no debrie (such as leaves and large seeds) gets to it ç.ç idk what to do
That’s a lot of guppies! But it shouldn’t be a problem if you maintain the same number. Obviously as they breed the biological load increases meaning more filtration is needed. But I’m guessing you will sell them....? that’s a lot of guppies 😂👍
@@Ozponds yes i will release them when they will be 1 month olf and grow out them in the pond and once they become 4 months old i will sell them. I don't want to breed them in that pond.
@@Ozponds you stuff is amazing...... There is little money for others so may not get the backing of bigger powers. I can see that this style will do the natural cycle far more affective than any other. Please elaborate as it’s gold for us that see the skill
@@Ozponds you are welcome. if you do what money maybe tech it spread sheet make a natural but amazing filler style people will buy in to it. Just like a cake mix in a box but for pond filter explaining the variables in an equation. Skill plus integrity will get you far. Maybe a pond king
The pool pump/filtration system hasn't run in years, and we just discovered is broken anyway. We were planning on replacing the sand in the filter with bio balls, but with the pump/I don't know broken, replacing it will be $$$ any ideas welcome
Depends a little on what your goals are for the pond. If you just want a few fish and loads of plants to attract wildlife you could probably just convert an ibc into a bog filter and run it via a submersible pump. If you want heaps of fish and less plants you’ll need a bigger filter and/ or bigger pump.
@@Ozponds Thank you for always replying so quickly ❤ We originally bought 24 native rainbow trout, 3 water lillies, 4 other plants that grow about 30-40cm deep. We added more plants. Then about 6 months later because we couldn't see the rainbow trout, we added 12 x 7-10cm koi, 12 x 7cm goldfish (dark colours and light colours), duckweed, more reed plants, irises, more water lillies, something that resembles elopea/hornwort? Naturally attracted native common brown frogs, a single heron, lizards etc. A further 6 months on and all the fish have bred, it turns out the rainbow trout were secretly building a mega army of baby fish. There are probably 400 fish in the pond now. All of this over the winter 2021 caused algal blooms from the high nutrients and bc we didn't have a filter/pump/aeration happening. We physically removed the algae and removed leaf fall/detritus from the bottom of the pond. The water is as clear as rainwater for the first 60cm, then a bit green. The algae doesn't bother us, but better visibility in the pond would be great. We can see the bottom in the shallow end (0.8m) but not the deep end (2.2m). We love the idea of swimming with our fish in summer. I suppose to do that we just want better visibility in the water. Thank you again :)
Thank you - yes please do make a video on how to make a filter thank you. My pond is green all the time and I have tried chemicals and other things , nothing works.
Hi ozponds. Thanks for this vid. Th long of building a pond as well but not the bottom filter one as I wasn’t to have a pond where I can breed fish like koi. Any tips would be great

Great and well explained.. The 200litr filter tank and much pond size or water can it filter?
I have it on a 3m x 4m pond (60cm deep).
What type of pump would you use on your sketch and where would you position it in the pond? You mentioned debris accumulating at the bottom of the filter but in aquariums I usually keep debris from getting into the pump
I’m not sure what sketch that was (it’s an old vid) but I always use a submersible pond pump. I prefer the pump be housed in a skimmer or intake bay. That acts as a pre filter and prevents large stuff being sucked into the pump. It also delivers oxygen rich water to the filter. Really fine material will pass through the pump and accumulate in the filter. These filters are only being flushed once a year.
@@Ozponds exactly what I imagined your response would be. Thanks for the info. Appreciate it
So for a 200,000 gallon pond I would need a 20000 gallon tub for a filter? I have a 180 gallon plastic tote and was planning on using that? Is that a no go? It is for koi fish and plan on stocking well but not overstocked.. thanks a bunch man awesome content 🙌
If you wanted to go the bog filter route, yes you would try and size at 10%.Of course you wouldn’t look for a container that size you would build a seperate filter pond. But that pond you are building is massive!! Is it receiving an inflow of water? If fresh water is constantly coming in filtration may be unnecessary. Another option is going a smaller filter but with a much higher flow. I think next week the waterfall filter video comes out. They filter the water with a smaller footprint but a bigger pump. The filter I built is too tiny for you but the principle can be scaled up. I hope that is helpful 👍
Enjoying your videos, thanks for sharing. Was that hydroton in for your bio filter? Looked like it, thanks probably will use it here when I get to that point.
Thanks I’m glad you’re enjoying the vids. The media in the bio filter was aquaponic clay balls. I think hydroton is the same or similar? It’s not a product we have in Australia but I remember a UK viewer mentioned it as a byproduct of pottery or clay businesses. If that’s the case I’m sure it will work great 👍
Hey Kev, you ever had issues with green water and needed to introduce mussels?
I have had green water issues in the past, but adding a bog filter has always solved them. I’m intrigued by fresh water mussels, but have been told they breed prolifically so I haven’t added them to any of my ponds yet. As I build more ponds I might experiment. Have you kept them? If so what has your experience been?
@@Ozponds i've kept them inside in tropical tanks. Had bad green water in my shrimp +baby guppy grow out tank, so popped two in there. They took it from pea soup to slightly stained in a few days and crystal clear in a little over a week., after that the plants took up the slack and haven't had an issue since. Thinking of getting some green water or a little wine barrel pond going in outside just to keep the buggers fed now! (rental house, so can't dig in)
I hadn't heard they're prolific breeders, but apparently part of their lifecycle is piggy backing on fish gills. Think that's what puts people off.
Awesome. Good info.
God, it's great. Almost like mine but unfortunately, my lake had crystal clear water for a week, then it started to lose its potential. my mistake is that I did not provide a channel for meat water. had a way to be cleaned? or do I have to start all over again?
I’m not sure I understand the question Alex. What’s meat water?
Great video. Do you have a protein skimmer?
No protein skimmer.
Great video! I have an issue. My bog filter system may have worked too well and I may have planted the wrong type of plants in it (alocasias) and after a year the tiny plants I planted are jurassic park sized. They are cemented in the container in one massive dense root ball and the water has stopped flowing from the cutout spillway. My system is a ~1 foot deep ~20 gallon premolded polythene pond liner with built in spillway cut out to which I added a bottom fed pvc pipe grid with holes drilled on the underside of the pipes. No separation between the layers and no drain. There seems to be no easy way to regain water flow. Any suggestions please?
Sorry you’re stuck. It’s a complete rebuild. If you watch my vids you’ll see I always recommended shallow rooted plants that can easily be thinned out. Good luck it’s no fun undoing all your hard work 😞
@@Ozponds Wow! Thanks for the quick response. I had a feeling that there's no easy way out of this. It's been amazing to see the big grow so quickly, We're going to miss the jungle it has become. Thanks for the content and response. Cheers
Thank you 🙏
You’re welcome 😊
WOW. Ta for the upload.
No problem 👍
Great video, but do I need to add bacteria?
It doesn’t hurt, but you don’t “need” too.
What is that horizontal woven looking tubing laying in your pond wedged under the rocks?
Some type of bio filtration media.
Is there a reason I see a lot of designs have the water pipe do a 90 degree turn down before releasing the water in the percolator? Can you just do a direct horizontal pipe line from your pump to the percolator?
The reason for me is that it means I don’t need to create another water proof hole in the filter. By coming in over the top I can also add in a breather pipe so that the filter doesn’t siphon empty if the pump stops. You can run it in horizontally if you want just make sure you have a way to prevent it siphoning if the pump shuts off. Hope that helps 👍
Do bunnings have those uniseal and bulkhead fittings?
They have the bulkheads. I’ve never seen uniseals there.
Nice system
Thanks. I like your pond too 👍
Awesome I want to know more
G’day Dale. I’ve since made videos on all the different diy filters I make. 👍 what else would you like to know?
I keep wondering how many hours per day your pumps are running water through the filter? Probably depending on the time of the year?!
Are you using solar pumps?
24/7. I’m in the process of building a solar powered pond. Will have a battery backup but only run 12hours a day.
@@Ozponds okay thanks. I guess a bigger filter can reduce the run times...
Not really. Filtration is dependent on the type of pond, the pond inhabitants and the owners desired outcomes.
Im building a small 2ft wide by 4ft long pond 8 inches deep. I want to put a mini bog filter for it. If the clean out drain is below ground, how can i pump the junk out on a mini bog filter?
Use a verticals pipe same as in my larger bogs. If you can stick a hose down, you can siphon the water out.
@@Ozponds God idea, thanks! I have some land I will be moving to in a couple of years. I'm planning on a larger pond with a full size in ground bog filter. Can hardly wait!
Thanks!
need help have pond one air pump fitting 18mm I need to adapt to 8mm air pipe any ideas? The pump came with a rubber tube that is about 18mm but can not seem to find a fitting for my large air stone that has a 8mm pipe.8
Sometimes the smaller hose will slide into the larger. Sometimes it’s snug if not maybe a little silicon to seal it up??
Thank you. Great Video. I understand how to build it. It is a simple, but smart design. I'm not too smart, so I have a question. Where is the water coming from for the inlet in the sketch you had in the video? Do I let water naturally fill it or do I have one of my pumps pushing water through it? Thanks for any help you can give?
Thanks mate 👍. You have e one of the pumps running water into the filter. Then so long as the outlet is higher than the pond water you let gravity put the clean water back into the pond. Hope that helps 👍
@@Ozponds thank you so much. It’s awesome to communicate with someone across the world. 😎
It is pretty damn cool 👍
love to see that filter video if you make it thanks
You found it 👍
Can the flow rate be too much for the bog filter as I may have gotten a bigger pump than what my volume of the bog is, I am having a fast flow. My pond is almost a week old and I have algae, will it clear up in time to come
The flow rate can definitely be to much for a bog. You want a slow flow up through the bog. You can have as much water as you like flow over the top. If your pond is only a week old you are going to have algae. It’s can take ages for a pond to mature.
I like the spilling pot sit on the pond side. Where did you get it?
That one came from a local plant nursery.
What’s a good size filter and pump for a 9x5 foot pond? 4.5 feet deep. Having a hard time keeping it clear. Around 30 small koi/ goldfish in as well.
Either a bog filter at around 20% pond volume. Pump size around the volume of pond per hour. You could build a waterfall style filter moving up to 4X pond volume per hour. That would help. You’re also probably a bit overstocked with fish. Good luck 🤞
Great vids, would this same logic apply for a pond/pool specifically for ducks? I've got six and want to setup a filter for their pool, instead of just draining it.
Yes it would. Although I’d imagine it needs to be quite big. If you imagine the biological load of a duck compared to a fish. They produce more waste, drop feathers and will bring in all kinds of dirt and other debris. The ducks currently think I built my dream pond for them 😬
@@Ozponds I think I am going to try a double filter sort of thing, where the bulk waste/silt as well as feathers gets filtered out first sort of like a skim? and then the that water gets filtered off to an actual filter container, with the intention that cleaning it out would be easier.
That sounds like a good plan. You definitely want to incorporate a skimmer or intake bay in the design 👍
@@Ozponds Do you think a swirl/vortex filter outputting to a biological filter would be sufficient? I had thought about getting a 14gallon barrel and doing a swirl filter at the bottom, with an enclosure around the input to act as a skimmer, then some sort of modular biofilter at the top, then purging the waste with an output at the bottom, and pulling out the biofilter to clean the skimmer enclosure when needed, but i'm not certain that the water wont be slow enough when traveling through the biofilter. The benefit though to breaking it down to two separate filters however would be being able to use the nitrate rich water from the vortex filter for the garden, before it passes through the biofilter.
Certainly sounds like a good idea. It’s not something I’ve personally done so you’ll need to be the test subject 👍
Hi, wanted to ask if you had to seal the urn before using it as the little waterfall feature? If so what sealant is safe for fish? Thanks
I didn’t seal it as the hole was so tight the hose only just squeezed through. But Firestone makes a good fish safe sealant 👍
@@Ozponds thank you so much for the reply, much appreciated 👍😊 I’ve had garden ornaments that I didn’t realise needed to be sealed and they started deteriorating due to being exposed to the elements so I didn’t want the same happening to the urn I’m intending to use as you have. I also didn’t want to accidentally poison the fish by using the regular pot sealers you get from Bunnings etc 😉 thanks again
Hi I have made a diy filter but struggle to get my water clear my filter contain stones big to medium to gravel there is no debris in the water only the green color is my concern. Can you give me advice what will clear up this green water? I have x3 gold fish inside
Make sure that the filter is sized correctly.
Thanks for the reply I will sized up my filter and see what happend..
How do you get the water go into the bog filer. Do you use the low speed pump or gravity, if you use the gravity, how do you do it?
Thanks,
G’day Loc. Yes a small pump moves water from the pond to bog filter. Then it flows back into the long via gravity. Hope that helps 👍
@@Ozponds Thanks for the quick respond and that leads to 1 more question. How many gallon per min/hr pump do you use for the pod filter and can I use 1 pump with a splitter for 2 or more pods?
Thanks,
It depends on the size of the filter how many gallons. If you haven’t already look at my flow rate for bog filter video, that should help you work that out. Just remember if you are going to split the flow to multiple filters or ponds increase the flow rate. This is where low volt adjustable pumps can be very useful. Hope that helps 👍
Can I add bio balls on top of the stones/gravel?
If you want to.
please I love this pond...can you make me one please for my 2 boys..
It’s an easy one to build yourself. Budget goldfish pond with bog filter
I have just purchased a pressure filter for my pond which I set up 4 days ago and its gone murky already (any advice on that would be great). My question is can I run my pond water through that, then into a home made filter like yours and then back into the pond?? I just don't want to not use the pressure filter as it wasn't cheap
I don’t use pressure filters. But yes you could run the water through the pressure filter and then into a bog or high flow filter like the ones I make. But I’m not sure why you would, the pressure filter needs regular maintenance.
How do you mean regular maintenance, regular cleaning?? I mainly purchased it as it was supposed to eliminate that as it has a handle that you pull up and push down which cleans the sponge filter as you move the handle, turn the valve so the dirty water doesn't go back into the pond. I've always made my own gravity filters but thought the pressure might be better as I was always cleaning the home made filters I made, maybe I should of researched more and made a better one
Yeap. They sound good that’s marketing 👍. The sponges usually get blocked quicker than you’d think. Then a pipe pops off because everything is under pressure. There’s not enough media for biological processes so they usually include a UV light to prevent the water turning green. But remember I’m biased! I like diy. I hope your one is maintenance free and keeps your water nice and clean 👍
What’s bringing the water from the pond into the intake filter?
The pump draws the water in and then pumps it to the biological filter (in most of my ponds that’s a bog filter). 👍
I have a whater mirror (large bird bath), and my pump turns on normally but get suuuper weak within a few minutes.... it has a external filter so no debrie (such as leaves and large seeds) gets to it ç.ç idk what to do
But is the filter clogging up?
If i have a 700 gallon pond and 700 guppies in it. So if i keep my bog 20% of pond size when will that be ok?
That’s a lot of guppies! But it shouldn’t be a problem if you maintain the same number. Obviously as they breed the biological load increases meaning more filtration is needed. But I’m guessing you will sell them....? that’s a lot of guppies 😂👍
@@Ozponds yes i will release them when they will be 1 month olf and grow out them in the pond and once they become 4 months old i will sell them. I don't want to breed them in that pond.
Thanks.
No problem Keith 👍
Did you make one more?
I made one of the small ones. Mini bog filter video. I still need to do one making the tall blue barrels.
@@Ozponds you stuff is amazing......
There is little money for others so may not get the backing of bigger powers.
I can see that this style will do the natural cycle far more affective than any other. Please elaborate as it’s gold for us that see the skill
Thanks mate. Your kind words made my day 👍
@@Ozponds you are welcome.
if you do what money maybe tech it spread sheet make a natural but amazing filler style people will buy in to it. Just like a cake mix in a box but for pond filter explaining the variables in an equation. Skill plus integrity will get you far.
Maybe a pond king
Thanks mate. Maybe something to consider in the future. At the moment just happy to help people create cost effective ponds that work.👍
What would you recommend for our pool to pond conversion? 35,000L
The pool pump/filtration system hasn't run in years, and we just discovered is broken anyway. We were planning on replacing the sand in the filter with bio balls, but with the pump/I don't know broken, replacing it will be $$$ any ideas welcome
Essentially what is the least expensive set up to filter the largest volume of water??? Thank you!! Love your channel ❤
Depends a little on what your goals are for the pond. If you just want a few fish and loads of plants to attract wildlife you could probably just convert an ibc into a bog filter and run it via a submersible pump. If you want heaps of fish and less plants you’ll need a bigger filter and/ or bigger pump.
@@Ozponds Thank you for always replying so quickly ❤
We originally bought 24 native rainbow trout, 3 water lillies, 4 other plants that grow about 30-40cm deep. We added more plants. Then about 6 months later because we couldn't see the rainbow trout, we added 12 x 7-10cm koi, 12 x 7cm goldfish (dark colours and light colours), duckweed, more reed plants, irises, more water lillies, something that resembles elopea/hornwort? Naturally attracted native common brown frogs, a single heron, lizards etc.
A further 6 months on and all the fish have bred, it turns out the rainbow trout were secretly building a mega army of baby fish. There are probably 400 fish in the pond now.
All of this over the winter 2021 caused algal blooms from the high nutrients and bc we didn't have a filter/pump/aeration happening. We physically removed the algae and removed leaf fall/detritus from the bottom of the pond. The water is as clear as rainwater for the first 60cm, then a bit green. The algae doesn't bother us, but better visibility in the pond would be great. We can see the bottom in the shallow end (0.8m) but not the deep end (2.2m).
We love the idea of swimming with our fish in summer. I suppose to do that we just want better visibility in the water.
Thank you again :)
@@Ozponds Loving the 1000L ibc idea. What pump do you recommend?
What do you use to pump the water to the filter?
Submersible pond pump.
Do you feed your fish?
Very occasionally. Mostly let them take care of themselves. But my ponds aren’t overstocked with lots of fish.
Thank you - yes please do make a video on how to make a filter thank you. My pond is green all the time and I have tried chemicals and other things , nothing works.
G’day Jenny. I’ve made the filter video. It was a few weeks back if you want to check it out 👍
Pls tell me solution for green pea soup
More filtration! Specifically biological filtration. This video will help you -Eliminate green pond water forever!
👍👍👍👍
My pond water getting green after 1st week 😓😓😓
Don’t worry almost all new ponds go green or get string algae blooms in the beginning. Things will balance out 👍
12 months and no established ... hmmmm
Not sure what you mean. Great name though 😉
If you play this video at 1.25 speed, it's much more watchable.
😂 so I talk to slow?
ahahahhacgenops
It says DIY.. didnt see how it was made.. mostly this guy is talking. Useless tome.
😂thanks for the comment anyway.
Hi ozponds. Thanks for this vid. Th long of building a pond as well but not the bottom filter one as I wasn’t to have a pond where I can breed fish like koi. Any tips would be great
I like using intake bays. Although even then I still find babies in the bog filter. I hope it was the eggs that went through the pump and not the fry.
Wow a whole 58 seconds before an AD
🤣
