Another good interesting video, I think I was born in the wrong century,I still use brushes and matting, but I have added a diy bakki trickle filter since watching all you guys on TH-cam. Good Luck and Stay Safe
Hi Tim , Great video and bang on what you say very interesting to watch , nice to see a dealer who is confident in a product and uses it. To a customer it fills you with confidence when you can see the item running that you are looking to purchase rather than loads stacked up and the dealer using 7 different filters on ponds . Keep the video's coming , be nice to see what koi are for sale and prices on a video. Keep safe
mark bate I agree. I don’t have a problem people selling many different filters. I just don’t want to confuse my customers with lots of different filters. We stick with the one now and sell a lot of units. We have looked at others but when you have the power of Evolution Aqua behind you and the support, there’s just no point for us. We use some add ons and even install drums for some clients, especially on old ponds because that’s all that will fit.
I take on board your nexus comments, I only got rid of my nexus for a drum because if the constant cleaning!!! Water quality and clarity were always very good. I figured if I installed the auto kit it’d be more to go wrong than on a drum so went with drum.
I understand that Mark. We clean our Nexus units twice a week when we are feeding high and the temps are high. It’s no issue for us. The Auto kits are really reliable to be fair, the 32,000 gallon pond only got some new ones on because the owner decided they were dirty 😂
Glenn Martin I don’t mind it at all. Please remember that not everyone can afford a drum. That’s why Nexus sell hundreds and thousands of the units the world over. They are by far the biggest selling in the world. You really have no idea how many ponds are out there, do you? I’ll just tell everyone who comes in my shop looking to build a pond “Glen said you can only have a drum for a pond, sorry” So you keep trying to spread the word, but remember, probably less than 1% of pond owners run a drum. Again, don’t mind cleaning them either.
Thank you for this and other very informative videos. So If I understand you right, you don't need to aerate in the pond, because the water going from the nexus is aerated enough?
We are planning to upgrade to a 6,000-gallon pond and would love your opinion on having a 2 bottom drains gravity fed filter set up. From the advice we've received so far, we had been thinking about a drum filter (75,000l) with a 1200 mm bio chamber and skimmer using 2 x variable 20,000lph pumps (run under capacity) for the returns to the pond. We have also been thinking about having a bakki shower for one of the returns, but that could be added later. We don't want to overdo the filtration if we dont need it, especially with rising electricity costs, and something reliable is important to us. Atm, we are pump fed (2,000-gallons), but we've always been told a drum filter is the way to go. I've noticed that many dealers/shops don't seem to use them and after seeing your informative video with the Nexus and bead filters, I'm just wondering what set-up you'd recommend? We've only been doing this for about 5 years, so we are still novices, so I'd really appreciate your thoughts 🙏🏻 Thanks.
Forgot to add: we think we'd need a 130lph air pump as we want aerated drains, or would be get away with eirher a smaller one or 2 smaller ones? We have 2 sterlets as well as Koi so O2 needs to be high. We've been told we'll need 2 x 80W UVs, does that sound about right? Pond will be in shade most of the time (under a sail/awning type structure). Many thanks for any advice. 🙏🏻
If your going down the drum route make sure it will handle the furthest drain as well as the closest one. Water finds its easiest route so the closer drain will always take the majority of the water. I would 100% add an Advanced filter to a skimmer line. Not sure why you want a shower. A 130 air pump would be fine for both drains. You can get the UV’s built into the drum.
Really appreciate the reply. Thanks. Would a Nexus handle this size pond? If so, what would you recommend, and would we need a bead filter, too? If so, what size should we look for? We wouldn't be heavily stocked, and our fish aren't very big (about 12" max). The Nexus does seem a more simple option, and I like the idea that there's no parts that can fail, as I've heard the drum ones can fail. We're only at the planning stage at the moment, so we have time to get it right.
Hi Tim, always been well pleased with the performance of my nexus 300 had it getting on for 13 years and still as good as the day I installed it. I would agree with Thomas's suggestions about showing us the opportunities to purchase other pieces that are available? Keep up the good work and looking forward to collecting the tosai 👍
A wise person once told me when I strayed away from nexus to other filters,”end the pain and go back to nexus,they work,I use them and I wouldn’t sell them if they didn’t work”. So I went back to nexus…… years later,no problems
Hi Tim Great video. I’m just about to upgrade our ageing koi pond filter. After watching your videos we are going to go for a nexus. Our pond is 1350 gallons with 12 koi, some very large!. We don’t have a bottom drain in the pond. What nexus model would you suggest
The problems I’ve found with the nexus filters and plastic media is that you can only filter one line with a a nexus, they do still leave fine particles in the water (you could see them on your underwater footage), and I’ve found as others have that plastic media doesn’t seem to handle nitrites/nitrates very well, but it is good at handling ammonia. When I had my nexus 220 I was never happy with the amount of “fines” in the water and it never really seemed to fully control the nitrites (always seemed to have a trace amount), and I had fairly high nitrates too.I took out the easy section and popped in a Draco drop in drum filter and that had pretty much gotten rid of the “fines” within a week, and I added a small bakki type shower with pumice stone in and that sorted the nitrite/nitrate issue - probably within two weeks, but the one that remained was that you could only ever filter one line, which would mean buying two filters, and running two pumps etc. Once you add up the cost of two nexus filters you soon start getting very close to the cost of a drum filter and a bio chamber, that would allow you to filter multiple lines, have higher throughput (say if you want to put 80% over a shower and 20% back through a mid-water return for example! Nexus filters are better than a lot of other cheaper alternatives, but they don’t even come close to a even a reasonable drum/bio chamber in terms of ease of use/water clarity etc etc.
I would agree in some parts but not others. There are many poor made drums out there, with very little back up etc from the makers, I’ve seen it many times. When a micro K1 bead filter is fully matured it will take down to a single micron. My long pond in the video had some fines because the pond was empty and we just added Koi, along with a bit of salt that stripped the algae. When everything is back to normal come and see our main show pond and find a fine. It’s amazing. Too much media in a Nexus will cause nitrite, always. K1 is how much you feed not your stocking rate. 100L of K1 can take 250grams a day of food. If you are not feeding this then there will be nitrite because you won’t seed the media. The biggest issue with Nexus is people who don’t run them correctly. Paul at Quality Nishikigoi has a drum, a very good drum, his water is good, no issues but he still maintains it for 20 minutes a week.
Also, the amount of people who build ponds with 2 drains is minute!! We have to take into account people with 1000 gallons - 4000 gallons. That’s 99% of the people who come into the shop. It’s great having 10,000 gallon plus ponds but we could not survive on those very few customers. We have sold 3 x Nexus 320’s this week. Ponds up to 4000 gallons using skimmers with the bead filters. Please don’t forget the so called ‘top end’ ponds are so few and far between.
Quality Nishikigoi my own pond was only 2800 gallons, but I wanted the ability to filter both my bottom drain and my skimmer line but without having to have two filters/ two pumps etc. Do agree on the comment you made about the cheaper drums and the lack of support from some manufacturers, but the Draco stuff is made in this country and the support is excellent, and as I said above, if you have more than one bottom drain &/or more than one line you want to filter (meaning you’d have to have multiple nexus filters if you wanted to use them exclusively), then at two nexuses your getting up to £2k in money and that puts you really close to the price of a good drum and bio chamber that will allow filtration of multiple lines, easier maintenance etc!
Matthew Thorp I still like keeping things separate but that’s just personal choice. The Nexus on bottom drain, and bead on skimmer is the best system in my opinion, and we have installed lots of these system as you can see on this channel and not a single complaint. Water is like glass. I have no issues with other filtration, none at all. However nothing breaks on a Nexus, I don’t have to ever go back to a job and fix anything like I have with drums... they are just not viable for me when I have an option that works.
Awesome content, and i do not even have fish. Been following you in Japan , some truly wonderful fish in beautiful condition. Them mud ponds are something to be hold.
Hi Tim . If my inner circle in my Nexus is higher than the outer circle have I got my Nexus to high. My pond is gravity fed to my sieve And then pump fed to my Nexus But I do have a bit higher than the water level on the pond.
I ran a Nexus 320 for 5 year's. They are quite good filters. I've also run beadfilter and bakki shower's. One of the drawbacks is the physical fine removal is a bit poor with the micro k1. The other things is people should remove all the k1 and check/clean the bio side near the feet. It had lots of air moving to media. I used a airtech 130 pump. But still crap builds up down there. The only thing that went wrong with mine was the air taps corroded and needed replacing.
Hey tim, I'm sure you have many more beautiful koi still unsold and if you have time to make another koi sales vid I'm sure many of us would love to see what's still up for grabs, not just the tosai but the nisai and older (I'm looking for a gin rin soragoi apparently Mrs P keeps saying 🤣). Thanks for sharing.
Great video. I'm planning my pond build and most likely going for a Nexus. Was thinking of an easypod but would prefer a 220. Cost is making it difficult though. I've seen a used 210 for around same price as a new easypod. Is there much difference between the 210 and 220?
@@TimWaddington Thanks for commenting and mentioning your used 320. A 320 might have been a bit big for my build. I've now found a used 220 which was only a half hour drive from me for £525 with a lid so grabbed that on Friday evening. Can't wait to start my build. Just deciding on other parts now and hoping to make a start next weekend. Your videos have been very useful and inspiring. Hope to visit your shop one day when I'm in your area.
Going to start the process of building a pond on the property soon (getting land dug up hopefully next week, fingers crossed) Do you happen to have any guides or tips? Anything would be appreciated!!
@@TimWaddington Awesome. Excavation is planned to start within the week, and from there I will order a bottom drain and add the piping necessary to exit off to one side. Is it advised to lay concrete? (I live on a half acre of dirt)
Also, I forgot to mention, I live in southern California. Temps can range from 0 Celsius some nights (winter) and we've had some temps get up to 46 Celsius.
Thanks this is really helpful. I'm planning g a 10,000 litre pond, would I need a Nexus 220 or 320? It would be slightly stocked with a bottom drain. Can you run a skimmer directly into the Nexus or does it always have to go through a separate bead?
I've had 2 drum systems in a year both have failed ( I won't name them but one cost £2100 pump+bio Combi ) I've gone back to a 220 Nexus and one Easy Pod on the skimmer line. If you think drums are the answer think again they are not all there cracked up to be they often fail and most of the pressure pumps supplied are just not up to the job. With a Nexus you just fit and forget. Great watch ;)
Hi Tim, fantastic video, thank you. Wonder if you could advise me? I never get a feeding frenzy when I feed my fish! Ever! All the parameters are all within tolerances but the fish just do not seem to want to rush up and get the food, they merely graze on it when they feel like it. Any suggestions you could give me? T I A Simon
Hi Tim, what was that treatment you used for the younger koi (Elvigin I think you said?) Do you sell it? or where would I be able to buy it? Many thanks, also great video's and very informative, I'm new to the hobby so your video's help out a lot :)
Hi tim love the content brilliant channel could I ask one question please when I have a power cut or turn off the power on pump why does it never restart and have to strip the pump out of pipe work it’s a older evolution aqua just can’t get my head round why it never starts back up again. ? Regards Tom
Sorry tim just looked my bad it’s a aqua forte 18000 🤯 I thort it was evolution aqua sorry can you still maybe shed some light on what’s happening with it all the best Tom
Forgive me as I am very new to this arena but I thought that the key was that there are two stages to filtration? 1) Mechanical 2)Biological If so the Nexus filter system is a compromise, trying to optimise both in one unit, I have recently been looking into the relative merits and pitfalls of systems as I plan to install a pond myself. From my uneducated view it appears that the best mechanical filtration is achieved via a drum as it can filter
Don’t forget, all moving bed filters use K1 media which is what Evolution Aqua make and have designed the new K plus media which is now used in most drum systems. I don’t agree at all that a shower increases bio. We tend to use the K1 Micro filter that when matured will take down to a single micron which has already been shown on the Tempest units. I explain why I only use the Nexus on my installs. Last year probably around 150 units. Bigger ponds I can fully understand why drum filters can be used. If you have multiple bottom drains it’s ideal to go into a single mechanical filter. My main rule has always been one drain to one filter so yes if more than 2 drains a drum is a good way. I just get the same results with the Nexus and bead systems. We have installed it so many time ls and it works. No moving parts, they cannot break. If a drum breaks down and you wait for parts your system is off, and it you have a separate system too, I don’t get why you have to. I have no issue with drums, we install quite a few but the amount of times I get reports of breaking and having electrical issues (I’m not saying they all do) but it makes it hard for me to sell them. I can fix a Nexus over the phone and done correctly they will filter just as good. Mechanical is important but when a system is mature, it’s about the bio.
@@TimWaddington Thank you for your prompt reply. So I have purchased a Profidrum combo 30 and was looking to add more bio after this. Would it be advantageous to add a Nexus 320 after the Profidrum instead of a simple moving bed. Would there be any advantage as there isn’t a massive price difference.
Love your Videos and you look after some great ponds, think I will need to pop to your shop after this Virus has gone , Where in Warrington are you based Again
Good afternoon Tim. Another good video. Although I don't use a nexus, I still use a K1 based media system. Its DIY and it does what it needs to be honest. The only other difference is that I have added Alphagrog just before a waterfall to clean up the nitrates. You mentioned medicating fish as precautionary measure. The question I have regards temperature and medication. I recognise your ponds are well heated. Unfortunately, mine is not. Although my fish look OK, there are signs on one or 2 that have little bits of sores coming out of winter, not a massive problem but I would like to prevent them getting worse. I am thinking of using NTLabs acriflavine to put in the pond, however the temperature is only just hitting 8 dg C. What are thoughts on using Acriflavine in water temperatures under 10dg? Regards Alex
Could you do a video on what to look for in a koi so discuss tosas, nissai etc what makes a show winning fish and also an ideal bowl of fish for a starter pond
I have thought about something like that but Koi are so subjective and would probably cause arguments etc. I will deffo do them when I am in Japan for sure.
Really enjoy the videos pal, some amazing looking koi. Can I please ask what the full orange koi with white tips on the fins are called? you have a nice one in the long pond. Thanks again pal 👍
It works that's why so many people use them, with very little issues. Nice shop btw👍. I'm looking at getting a Nexus 220 for these very reasons. One question though. If I was to put the full 150 litres into the nexus. Would the 95 air pump be enough or would the 130 be better. As I did see in another video 11000gal with 2 320's running off one 130pump? Cheers and enjoying the content.....
@@TimWaddington Hi thanks thanks for the reply. Well to be honest I'm not really sure how much I should use. It was more of a long term thing, if I needed to add more later. Pond is roughly 2300 gallon. With 8 koi 8 to 10 inch or so. May have to house 3 more for a house move.
Why not add as much media as is posible. It wont harm the system, if anything it will help. I run a Cetus Sieve, a 320 with 300 lts of K1 and a 150 air pump. Water quality is excellent and I can't stop the fish breeding every year
Hi Tim Thank you for this video. Ive just installed a nexus 320 a couple a days ago on my 13000 litre pond. How can you get the k1 to mature quicker? Pp? Filter gel any suggestions would be great
Hi Tim, always a pleasure to watch your movies. little question, i have a nexus 220 on my quarantine system, with good water condition, except NO2 and NO3, always keeping them high on 0.8. what kind of bacterial liquid do you use? greetings from Belgium
I currently have a nexus 320 running pump fed and I was looking at changing the pump for a vari model, I wanted to ask you some advice. Would I still need to install the pump submerged or could I install it above water and have the pump pull the water from the pond into the filer. Thanks in advance.
Quality Nishikigoi thanks for the reply. Bottom drain isn’t an option as pond is n the edge of the garden and is sloping so filters had to go above. How do you rate the bottom drains that sit on top of a lining would you use these or stick to the housing of the pumps?
Hi mate very brilliant video thanks for that .. can you please let me know if I need this whole system in India can you guys help me to build or what I need to to do .. thanks
Where are you based Tim, id love to visit your shop mate, ive been looking for a good quality yamabuki ogon for a while my big one had an internal ulcer and i had to put her out of her misery, sad day!
Hello there, my question is as for now I have my 2 bottom drain feed to ultrasieve 3 and then go to my bakki shower. If I want to get this nexus 320 as a upgrade, can I run my 2 bottom drain to this nexus 320?
@@TimWaddington thanks, I was thinking of the 320 as people have advised me to half the gallons it can handle and then half it again for koi ponds. What’s the maximum a nexus 220 would handle gallons and amount of koi?
@@TimWaddington I could fit a nexus 320 next to the pond but it’s getting it in my garden the problem as it will not fit through my back garden gate and I share an entry with my neighbour so there is no other way! Shame
Hi, can you give me some help and advice please, i have a pond 10ft long 5ft wide and just under 4ft deep, its pump fed using a 11000 pump going into 55w pro clear uv then through a Y splitter to a easypod and 4 bay mini kockney koi chamber but i am struggling big time with water levels, if i upgrade to a nexus 220 will this solve my problems
Hi everyone I suffered with flukes in my pond last year that affected a few of my koi and lost about 11 fish in total. I did treat the pond with flukesol but 12 months on I'm still getting infected fish. I've had koi for about 20 years but never suffered like this before. I've tested the water in every way and all comes back as perfect is their anything else I'm missing or has anyone else suffered the same thing and been able to cure this. Cheers Gez
Quality Nishikigoi But the levels are balanced , only 1 drain isn’t working for what I’m seeing. The first drain is clean of waste ect.. and the second one is a mess with a lot of waste around it. That’s why I made the decision to switch filters, but for now it keeps my water clean and my water values excellent.
great video, lovely setup love to come up from cardiff one day and get some koi for our ponds... I run an early version of the nexus, would you recommend the bypass kit ???, i've fitted an easy and removed the original sponge
@@TimWaddington fantastic a 6000 to 8000 litres per hour but clog up any faster ,thats why you use superfisf low energy pumps ,if you get a ULTRASONIC flow meter i think you will find tht you are only gettin a MAXIMUM of 6ish thousand litrs per hour which tallies up with the TEMPEST
Stephen Leung it all depends on the pond. We recommend a single drain up to 4000 gallons with a single Nexus 320. Then we look if we are adding a skimmer, where we add a bead.
I'm getting a nexus 320 and a Cetus Sieve and 55w uv for my pond with 14000lt Is that good set up or no? Love watching your videos. I've uploaded my pond build if you want to check them out, let me know what you think. Thank you for your youtube channel 👍
You can't fault K1 for bio, I've not used the modern ones so I can't comment on mech but my good old original 200, is good at it but not the greatest( even with a Cetus before it), as is the same with all filtration systems, if it works for you your going to recommend them and you can't fault that logic, Steve over here swears by drums, Joanne over here swears by showers, both work for them Nexus works for you so why not recommend it, clearly you think they are epic. Thanks for putting out more content in these difficult times, stay safe.
Or make your own barrel system that does a much better job for a fraction of the price? I hate how the koi hobby these days is making everyone believe if you don’t have a nexus or anything evolution Aqua then your pond isn’t adequate.
@@TimWaddington Is there a meter that you could put inline to accurately check the flow. The pump is probably 2m from the inlet of the easy pod. What do you think of the EA vari pumps ?

Nexus filters are better than a lot of other cheaper alternatives, but they don’t even come close to a even a reasonable drum/bio chamber in terms of ease of use/water clarity etc etc.
I would agree in some parts but not others. There are many poor made drums out there, with very little back up etc from the makers, I’ve seen it many times. When a micro K1 bead filter is fully matured it will take down to a single micron. My long pond in the video had some fines because the pond was empty and we just added Koi, along with a bit of salt that stripped the algae. When everything is back to normal come and see our main show pond and find a fine. It’s amazing. Too much media in a Nexus will cause nitrite, always. K1 is how much you feed not your stocking rate. 100L of K1 can take 250grams a day of food. If you are not feeding this then there will be nitrite because you won’t seed the media.
The biggest issue with Nexus is people who don’t run them correctly. Paul at Quality Nishikigoi has a drum, a very good drum, his water is good, no issues but he still maintains it for 20 minutes a week.
Also, the amount of people who build ponds with 2 drains is minute!! We have to take into account people with 1000 gallons - 4000 gallons. That’s 99% of the people who come into the shop. It’s great having 10,000 gallon plus ponds but we could not survive on those very few customers. We have sold 3 x Nexus 320’s this week. Ponds up to 4000 gallons using skimmers with the bead filters. Please don’t forget the so called ‘top end’ ponds are so few and far between.
Quality Nishikigoi my own pond was only 2800 gallons, but I wanted the ability to filter both my bottom drain and my skimmer line but without having to have two filters/ two pumps etc. Do agree on the comment you made about the cheaper drums and the lack of support from some manufacturers, but the Draco stuff is made in this country and the support is excellent, and as I said above, if you have more than one bottom drain &/or more than one line you want to filter (meaning you’d have to have multiple nexus filters if you wanted to use them exclusively), then at two nexuses your getting up to £2k in money and that puts you really close to the price of a good drum and bio chamber that will allow filtration of multiple lines, easier maintenance etc!
Matthew Thorp I still like keeping things separate but that’s just personal choice. The Nexus on bottom drain, and bead on skimmer is the best system in my opinion, and we have installed lots of these system as you can see on this channel and not a single complaint. Water is like glass. I have no issues with other filtration, none at all. However nothing breaks on a Nexus, I don’t have to ever go back to a job and fix anything like I have with drums... they are just not viable for me when I have an option that works.
Brilliant video made it all sound simple mate
is it possible to buy a lid for the nexus filter, so the sunlight is blocked out?
Yes Martin, they have lids for them 👍
@@TimWaddington Thanx
Awesome content, and i do not even have fish. Been following you in Japan , some truly wonderful fish in beautiful condition. Them mud ponds are something to be hold.
Thanks Keith!! I am really missing Japan at the moment, I should be there and wish I was 😞
Hi Tim . If my inner circle in my Nexus is higher than the outer circle have I got my Nexus to high. My pond is gravity fed to my sieve And then pump fed to my Nexus But I do have a bit higher than the water level on the pond.
I ran a Nexus 320 for 5 year's. They are quite good filters. I've also run beadfilter and bakki shower's.
One of the drawbacks is the physical fine removal is a bit poor with the micro k1.
The other things is people should remove all the k1 and check/clean the bio side near the feet. It had lots of air moving to media. I used a airtech 130 pump. But still crap builds up down there.
The only thing that went wrong with mine was the air taps corroded and needed replacing.
Cheers Tim, great vid
Really enjoyed video can I ask what food do you feed I use medikoi wheatgerm and garlic in colder months great video
We sell our own branded food Dave. One of the range has garlic in it too.
Ok thanx really interesting video great koi you have only live on wirral so have to come up sometime this year takecare keep safe
Hey tim, I'm sure you have many more beautiful koi still unsold and if you have time to make another koi sales vid I'm sure many of us would love to see what's still up for grabs, not just the tosai but the nisai and older (I'm looking for a gin rin soragoi apparently Mrs P keeps saying 🤣).
Thanks for sharing.
Yes that’s a good idea. Will try and sort, things have gone a bit mad on sales though.
@@TimWaddington just trying to keep you busy and us entertained 😉
Noted 👍
Great video. I'm planning my pond build and most likely going for a Nexus. Was thinking of an easypod but would prefer a 220. Cost is making it difficult though. I've seen a used 210 for around same price as a new easypod. Is there much difference between the 210 and 220?
220’s are the better unit. If you could fit a 320 in there, I have a second hand one at the shop
@@TimWaddington Thanks for commenting and mentioning your used 320. A 320 might have been a bit big for my build. I've now found a used 220 which was only a half hour drive from me for £525 with a lid so grabbed that on Friday evening. Can't wait to start my build. Just deciding on other parts now and hoping to make a start next weekend. Your videos have been very useful and inspiring. Hope to visit your shop one day when I'm in your area.
Going to start the process of building a pond on the property soon (getting land dug up hopefully next week, fingers crossed) Do you happen to have any guides or tips? Anything would be appreciated!!
Most important of you are building a new pond...Bottom Drain.
@@TimWaddington Awesome. Excavation is planned to start within the week, and from there I will order a bottom drain and add the piping necessary to exit off to one side.
Is it advised to lay concrete? (I live on a half acre of dirt)
Also, I forgot to mention, I live in southern California. Temps can range from 0 Celsius some nights (winter) and we've had some temps get up to 46 Celsius.
Thanks this is really helpful. I'm planning g a 10,000 litre pond, would I need a Nexus 220 or 320? It would be slightly stocked with a bottom drain. Can you run a skimmer directly into the Nexus or does it always have to go through a separate bead?
Buying a nexus is best money I've ever spent. after using various filters over the years I can say the nexus is by far the best
We agree! 👍
Loved it Tim! Thankyou
Cheers mate 👍
Great video - very helpful
I've had 2 drum systems in a year both have failed ( I won't name them but one cost £2100 pump+bio Combi ) I've gone back to a 220 Nexus and one Easy Pod on the skimmer line. If you think drums are the answer think again they are not all there cracked up to be they often fail and most of the pressure pumps supplied are just not up to the job. With a Nexus you just fit and forget. Great watch ;)
Hi Tim, fantastic video, thank you. Wonder if you could advise me? I never get a feeding frenzy when I feed my fish! Ever! All the parameters are all within tolerances but the fish just do not seem to want to rush up and get the food, they merely graze on it when they feel like it.
Any suggestions you could give me?

Spend every day around them a lot mate. Also Tosai are often like that.
Hi Tim, what was that treatment you used for the younger koi (Elvigin I think you said?) Do you sell it? or where would I be able to buy it? Many thanks, also great video's and very informative, I'm new to the hobby so your video's help out a lot :)
Elbagin. No unfortunately we don’t sell it. Not allowed
now if i buy it can you fit it ?
looking at a 320 auto
Where are based
Hi tim love the content brilliant channel could I ask one question please when I have a power cut or turn off the power on pump why does it never restart and have to strip the pump out of pipe work it’s a older evolution aqua just can’t get my head round why it never starts back up again. ? Regards Tom
Tom Buck is it the sequence pump? With the basket?
Sorry tim just looked my bad it’s a aqua forte 18000 🤯 I thort it was evolution aqua sorry can you still maybe shed some light on what’s happening with it all the best Tom
Is it above or under the water level? Does it have a basket on the front of the pump?
Under the water level outside the pond the pump is after a sieve before a bead filter then uv then return regards tom
Yeah it’s probably air filling the basket when you turn off and then won’t prime
Great video 👍
Thank you 👍
Forgive me as I am very new to this arena but I thought that the key was that there are two stages to filtration?
1) Mechanical
2)Biological
If so the Nexus filter system is a compromise, trying to optimise both in one unit, I have recently been looking into the relative merits and pitfalls of systems as I plan to install a pond myself. From my uneducated view it appears that the best mechanical filtration is achieved via a drum as it can filter
Don’t forget, all moving bed filters use K1 media which is what Evolution Aqua make and have designed the new K plus media which is now used in most drum systems. I don’t agree at all that a shower increases bio.
We tend to use the K1 Micro filter that when matured will take down to a single micron which has already been shown on the Tempest units.
I explain why I only use the Nexus on my installs. Last year probably around 150 units.
Bigger ponds I can fully understand why drum filters can be used. If you have multiple bottom drains it’s ideal to go into a single mechanical filter. My main rule has always been one drain to one filter so yes if more than 2 drains a drum is a good way. I just get the same results with the Nexus and bead systems. We have installed it so many time ls and it works. No moving parts, they cannot break. If a drum breaks down and you wait for parts your system is off, and it you have a separate system too, I don’t get why you have to.
I have no issue with drums, we install quite a few but the amount of times I get reports of breaking and having electrical issues (I’m not saying they all do) but it makes it hard for me to sell them. I can fix a Nexus over the phone and done correctly they will filter just as good. Mechanical is important but when a system is mature, it’s about the bio.
@@TimWaddington Thank you for your prompt reply.
So I have purchased a Profidrum combo 30 and was looking to add more bio after this. Would it be advantageous to add a Nexus 320 after the Profidrum instead of a simple moving bed. Would there be any advantage as there isn’t a massive price difference.
@@waynebailey8619 no, definitely a bio chamber. You can get more flow.
@@TimWaddington load of crap
Hi, what would you recommend for a 2400 gallon pump fed pond. Was thinking about an easypod auto. Are they any good? Great video by the way.
Iain Busbridge not for that size pond Iain, you would need a Nexus 220. A pod not big enough.
@@TimWaddington Thankyou for your quick reply
Love your Videos and you look after some great ponds, think I will need to pop to your shop after this Virus has gone , Where in Warrington are you based Again
Woolston Barry. Look forward to seeing you
Fantastic, just fantastic
Good afternoon Tim. Another good video. Although I don't use a nexus, I still use a K1 based media system. Its DIY and it does what it needs to be honest. The only other difference is that I have added Alphagrog just before a waterfall to clean up the nitrates. You mentioned medicating fish as precautionary measure. The question I have regards temperature and medication. I recognise your ponds are well heated. Unfortunately, mine is not. Although my fish look OK, there are signs on one or 2 that have little bits of sores coming out of winter, not a massive problem but I would like to prevent them getting worse. I am thinking of using NTLabs acriflavine to put in the pond, however the temperature is only just hitting 8 dg C. What are thoughts on using Acriflavine in water temperatures under 10dg?
Regards
Alex
Just Alex Koi Ponds I would probably use acriflavine with salt right now. I would however think there could be some parasites in the pond.
@@TimWaddington A very quick response! Your advice is much appreciated. I'll do it asap. Many thanks.
Regards
Alex
Could you do a video on what to look for in a koi so discuss tosas, nissai etc what makes a show winning fish and also an ideal bowl of fish for a starter pond
I have thought about something like that but Koi are so subjective and would probably cause arguments etc. I will deffo do them when I am in Japan for sure.
Really enjoy the videos pal, some amazing looking koi. Can I please ask what the full orange koi with white tips on the fins are called? you have a nice one in the long pond. Thanks again pal 👍
Benigoi mate 👍
It works that's why so many people use them, with very little issues. Nice shop btw👍. I'm looking at getting a Nexus 220 for these very reasons. One question though. If I was to put the full 150 litres into the nexus. Would the 95 air pump be enough or would the 130 be better. As I did see in another video 11000gal with 2 320's running off one 130pump? Cheers and enjoying the content.....
Why would you need the 150L of media?
@@TimWaddington
Hi thanks thanks for the reply. Well to be honest I'm not really sure how much I should use. It was more of a long term thing, if I needed to add more later. Pond is roughly 2300 gallon. With 8 koi 8 to 10 inch or so. May have to house 3 more for a house move.
adam rudge at those levels the 50L that comes with the unit is fine
Ok then. Thanks for the info. Btw is the 95 air pump enough? It's only running the nexus. Will probably run a retro drain off the existing air pump.
Why not add as much media as is posible. It wont harm the system, if anything it will help. I run a Cetus Sieve, a 320 with 300 lts of K1 and a 150 air pump.
Water quality is excellent and I can't stop the fish breeding every year
Hi what is your web site as new to fish keeping but looking to set up filter and pump on new pond i building
Thanks shawn
Great vid and kits brilliant content thanks mate
Thanks Colin 👍
Hi Tim
Thank you for this video. Ive just installed a nexus 320 a couple a days ago on my 13000 litre pond. How can you get the k1 to mature quicker? Pp? Filter gel any suggestions would be great
No need to PP it, no idea whoever thought that up. Just have to be patient mate
Quality Nishikigoi was told to pp it as PP removes the manufacturing residue and helps it mature much quicker and will sit lower in the inner ring.
Something the company says makes no difference at all, I’ve never ever done it
Hi Tim, always a pleasure to watch your movies. little question, i have a nexus 220 on my quarantine system, with good water condition, except NO2 and NO3, always keeping them high on 0.8. what kind of bacterial liquid do you use? greetings from Belgium
How big is the pond and how much K1 in the Nexus?
8.000 liter, and i have 18L K1 inside and 100L outside.
De Spie how many Koi?
4 koi in this system
I currently have a nexus 320 running pump fed and I was looking at changing the pump for a vari model, I wanted to ask you some advice. Would I still need to install the pump submerged or could I install it above water and have the pump pull the water from the pond into the filer. Thanks in advance.
Kurt Marshall I guess is possible but not really how they like to work.
Quality Nishikigoi thanks for the reply. Bottom drain isn’t an option as pond is n the edge of the garden and is sloping so filters had to go above. How do you rate the bottom drains that sit on top of a lining would you use these or stick to the housing of the pumps?
The case is fine, I’ve never used the one you said so don’t know mate.
Quality Nishikigoi thanks for the advice. Keep the videos coming I believe your helping keep a lot of people sane. :)

Question, do you can’t put 2 drains on 1 nexus?
It’s not recommended, no. It’s no hard to balance them and the Nexus will never run properly because the levels will be all over the place.
Quality Nishikigoi I got that right now. That’s why I probably gonna switch to an drum filter.
Yeah, you can put 2 into most drums 👍
Quality Nishikigoi But the levels are balanced , only 1 drain isn’t working for what I’m seeing. The first drain is clean of waste ect.. and the second one is a mess with a lot of waste around it. That’s why I made the decision to switch filters, but for now it keeps my water clean and my water values excellent.

You can't fault K1 for bio, I've not used the modern ones so I can't comment on mech but my good old original 200, is good at it but not the greatest( even with a Cetus before it), as is the same with all filtration systems, if it works for you your going to recommend them and you can't fault that logic, Steve over here swears by drums, Joanne over here swears by showers, both work for them Nexus works for you so why not recommend it, clearly you think they are epic.
