hi, i didn't much understand how the water goes back to the pond but I've been looking for this video and thanks anyway

How much lph is the pump?

Will this work with a planted pond? I mean with a substrate?

You put a lot of work into your system but I cannot help to mention how dark and murky the water is with all that equipment. One would think with all those filters the water would be crystal clear. I'm not bashing you, just giving an honest opinion.

Nice job mate, really made it clear how the gravity-fed filter & Pump-fed filters works

My pond is round the corner to filters question is there a easy way to set gravity filter water level to pond level . richard

Some really cool system you got there mate, I will definitely add the parallel connection for the uv light.

Great video it helped me a lot. I am making a pond type pool , 3 meters round and it will be 120cm deep with a walk in slop. I want it to look like a pond and it will have a waterfall above it. Its more for looks in the garden but on the hot days i want to walk into it to cool down, my question is do you think the slooing system you mentioned will work for me and waht type of pump do yiu recommend? 🤞🏾

That was a nice demonstration using a really good design. Thanks.

Whats the dimensions?

What makes the top float? Is it the air trapped by the blue coloured ring?

You answered all my questions whithout my asking them. You wouldnt blv the hours i ve spent reading and researching the idea of a filter free pond. I'm so glad to be strating from scratch. Thanks so much for a very clear explanation.

Great video, thanks! Quick question - if you didn't want to put a hole in the pond wall, so no bulkhead, would it be possible to run the pipe up and over the pond wall?

really nice build , what is are the dimensions of the pond?

Very informative! Thanks

What about adding a skimmer connected to the suction line in order to improve filtration and skim the top part of the water.

Thank you for this video. A lot of other videos only show the building process without a proper diagram. This makes it easy for novices to understand.

Nice explanation, that’s how I have my koi fish pond bottom drain a gravity f system

hi, is your filter same level as your pond?bcoz on your drawing it seem little higher..thanks

Diy not 3d printed lol

Do you try your plan in real it is work?

Great video. I'm trying to figure out flow rate and pipe sizes for over stocked pool? Is the whole idea to match the correct pipe size to pump size so there is no draw down in each chamber/barrel so you have a lower flow rate? Or in an over stock koi pond/pool would it be better to oversize my pump to have draw down in each chamber or barrel in my case. I was planning to have two retro fit bottom drain pipes going into my 1st 55 gallon static K1 barrel with both being 2"/50mm pipes, than into the 2nd 55 gallon static K1 barrel with a 3"/76mm pipe, then into my 3rd 55 gallon moving bed K1 barrel, then into my 4th 55 gallon moving bed K1 barrel then to a dry 3500 gph/13248 lph pump back to the pool water fall. I figure a ball valve/gate valve can be closed off before the pump to adjust the flow rate? Thanks all for any help asap.

yeah i also use just regular bins for my filters. mines a bit more low tech but it works, its cheap and easy to build,./ awesome system., cheers mate

Nice man I'm about to do something similar to this but no plants 😢 hey what did you use to paint your top copings of the pond with if it's regular paint that's not bad for the fish have you heard?

Maybe a silly question but a lot of in pond pumps say that they can’t be used for swim ponds due to the risk of electric shock. Dry run pumps that you sit 2m away and lower than the pond level seem to be more expensive compared to submerged pumps with the same L per hr capacity. So is it safe to put a submersible pump into the filter system fed by a bottom drain, as surely this water is a continuous route of electric conduction back to the pond? Thanks

Very good explanation, thank you.

I have an idea that if you can wifi control the water fill, you can also wifi activate aeration for the pond. But I guess if the power goes out while you’re away, a solar pump and battery pack will have to activate till the power comes back on…

This is perfect! I am currently rebuilding my pond and this has explained / made me understand this a lot better. I have a couple of questions through, is it literally just gravity / water pressure that sends the water from the bottom drain into the filter? Does it matter where the filter is placed, for instance can it be higher than the pond or does it need to be the same height or lower? and is it worth fitting some sort of valve to stop water coming into the filter to carry out maintenance on the filter or would that just cause problems?

I'm a novice in process of building a raised planter with a pond at one end and came to the same conclusion as you have here - that the pump will work much better in a relatively clean water chamber. Allow gravity to do as much of the work as possible. Glad I found this video because I have been posting on a pond forum and copped for some flack.

Exactly what I needed to be explained - and crystal clear. Thanks!

how does distance and amount of pipe turns affect the system? or does it ?

Some pipes could be just too small. i think that is restricting the flow. Especially the one that brings the water through the bottom drain through the wall. If you would drill the holes lower you wouldnt achieve anything as the water would just be pumped away and you would have the water levels even lower.

Hi What do you think about shower filer ?

Saw your vid a bit late. Designed mine using the first one and every 3-4 weeks i have to get inside the pond to clean out the pump. quite the hassle.

Thank you very much for your helpful video. I really like the gravity fed filter design together with the sloped floor fishpond. Do you think this system will also work well for fish farming? How much slope or pitch should the pond floor have? I appreciate it very much if you have time to respond.

I want to build a waterfall, what about the filters not being on the same water level? will it work? I guess will need an extra pump to get the water all the way to the top of the waterfall

I’m definitely going with the dedicated bottom drain. Thank you for the info :) I can’t wait to start digging.

The fish look great!

Hello Neil, How about improving further by placing a drain pipe at the bottom or at the side of your mechanical filter compartment for cleanup, will it be okay? I am about to build my own pond and came across your channel. Thank you.

is this really work?, because the water level of the fish pond and the water level where the water filter is the same level how does it circulate thru gravitity?

Good sharing! I had a gravity fed bottom drain system for my Koi before.. the problem was that after about 2 years..gravel/leaves/sand settled at the bottom of the pipe and choked the whole system. I got a plumber to flush it out with pressure jets but was unable to clear the sediments completly. I got a handy man to seal my bottom drain and did a retro fit piping like yours but added slopes with concrete and have had no issues for the past 5 years.

Can you recommend someone to assist me .I am in hilton kzn

Really helpful, I was about to go pump fed and will now redraw my plans. Better now the in 2 weeks time! :)

Great job, do have any updates?

So can a pond have a bottom drain and a bog filter? Would that work?

what happen if the electricity is out? or brownout? Is it gonna overflow in the filtration chamber? please reply..

At last,straight to the point and great explanations of how it all works

What is your solution or what would you recommend to clean as much muck as possible in the flat bottom pond?

bien explicado lleva toda la razon.

What happens when electricity goes off...will the bottom drain not overflow the filter system n empty the pond???
