Hello Terry, i'm new to the Koi pond experience. I have a water feature that has 1,200 gallons of water. I want to use your filter, the smaller one, to get the pond ready for Koi next spring. The pond does have a skimer but no filtration for fish. Love your system !

[@Wrighty]

Hi, I'm contemplating a 20,000ltr koi build. 4.5mx3mx1.5m Will this system be enough to filter the pond

[@Wrighty]

Hi Mathew, I make that just under 4500 uk gallon. For that size pond you would need the Pro system. It's the latest design. I run it on my pond and I love it. You'll find it on my website diypondfilters.com Here is a video showing it. kzbin.info/www/bejne/mGW3aYehh7mLd9E you can contact me on [e-mail] Terry.

[@Matt-pt3vq]

Wrighty cheers will take a looks. couple of other related questions, I want to come out of the filter into a plant bog before overflow into pond, do you think that would be a problem. also can this be fed from a bottom drain? Oh and I would prob consider putting a large debris whirl chamber before this as we get a lot of leaf drop round here from neighbours, guessing that should get ok, just want to to leave the leaf sludge to be hooked out for the compost

[@Wrighty]

Running it to a plant bog is not a problem. I run mine from a bottom drain with a 8000 lph dry pond pump. Fitting a vortex barrel first is also easily done. you simply add another tub as the first tub. If I can help further just give me a shout. Terry.

[@DrumFilterRau]

Appreciate the video! You might find a drum filter even more convenient - it’s automatic, cleans water effectively, and handles even small particles that other filters might miss. The maintenance is simple, and the electricity costs are super low - around 50 cents a month. For those looking for efficiency and ease, this is an ideal solution for pond maintenance.

Hi Armando, Good to hear you got the return sorted mate. Did you soak the media for 2 days first? If not it will take a while to settle and become neutrally buoyant. It's because it's new. 50 ltr in a 55 gallon tub should be ok. you can try and take some out so it's moving, and add it back later. You can buy baby koi graduals, you'll find them on eBay. Terry.

Great little filter Terry, Using a smaller air pump was great info. When refitting my pond with your Large filter system I worked out that, 240 watts will cost about £216 a year to run 24/7. Its well worth doing some homework for pump specs etc, you could save quite a bit on a years running cost by checking the full specs of the equipment you buy. All the best Tony

***** Wow! you don't realize just what your using. Thanks for that tony. Terry.

[@oaksho]

Wrighty I think your pump looks like a "Blagdon Force hybrid 16000 which runs at 260 Watts? Running 24/7 for a month = £20.47 I'm running a German made, Aqua Forte 20000 at 200 Watts, cost 15.75 a month. My 55 watt UV costs £4.72 total £20.47 the same as your pump. Just as an example. Although these figures are based on a 10.583p per kWh Hope this helps someone. All the best Tony

Working on a similar system...but my barrels lost their roundness when I removed the top...is this normal?

[@Wrighty]

If you cut into the side of the top and not down through the top, the barrel walls will become very unstable. Always try to leave a top rim of some sort. If you have a look at this video it shows the barrels have been cut down from the top, leaving a rim to strengthen the barrel walls. kzbin.info/www/bejne/iKjGeZyurbuooNk Hope this helps. Terry.

Another excellent build, Terry. Just when you think you have done everything possible, you can always find another thing or two to tweak.

What pond size would this suit? Adding more barrels, would this increase the pond size it could be used on? I'm planning on doing this on my 7500 gallon pond. However would 2" be OK? Planning on entering the drums from a 4" gravity fed and then using 2" piping for rest of it. Just trying to figure amount of barrels I need and size pump this would handle for returning back to pond. Thanks!

[@Wrighty]

Hi Chaz, The Midi system is only good to 4000 gallon ponds. You would need my Pro system for that amount of water. You would also need a pump around 1700 gph. 2 inch pipe would not be big enough for that flow. Have a look at my Pro system, that will cope with up to 10000 gallon ponds.

thanks so much for all your videos. we have our system up, but a few little barriers, have not completed the waterfall and landscaping, so pictures will come later. We did use the 2" pipe working fairly well. Used 2 filter cages in each barrel for additional flow. so glad you noted on this video how much media, because I didn't think I had enough, and I was right! Ordering more today. We are having little issue on the 1st tank and is not allowing us to open the valve from the pump 100%. Tank 1 is filling up faster than 2 and 3. any suggestions. I had tried to use some of the larger media on tank 1, that sinks since we have not completed the pipe connections from the bottom drain (we think that might be the issue) Im going to pull it today and see if that makes a difference. We also set the filter cages so we can turn them to help adjust the water flow as well, that also helped.

What kind of air stone did you use in your moving bed with the 1.6L/min air pump?

[@Wrighty]

I used a 12 air bar, but you can use a 5" round air stone. To use the smaller air pump, you will need a good flow through the filter, as the 90 elbow inflow is pointing upwards it helps to move the media. Terry.

[@PTranProductions]

@@Wrighty Thanks Terry! Yes, I am using a 5” round air stone with a 4W 6.8L/min pump. Hopefully this will be strong enough. I did try out the 1.6L/min pump but it was not strong enough for the 5” stone. As my first trial of my build, K1 media just float on the surface without any moving action. Should I soak the K1 in Potassium Permanganate to speed up the maturity or should I just wait?

[@Wrighty]

Hi mate, it will become mature in a few days. It won't circulate until it is mature. I wouldn't PP it mate, or it could be quite a while before bacteria start to mature. Just keep giving it a good stir with your hand now and again. Terry.

How do you clean your filter?

Here's a video of me cleaning the Pro filter in real time kzbin.info/www/bejne/rZiulIGLjbZmopI Terry.

[@nochanceman8181]

i havent read thtough all the comments but whats the pump size/ flow rate going into your filter? ive used 1.5" pipe and my new pumps 15000ltrs per hour and its too much for that size pipe. was gonna go 4" pipe but depending on yours im wondering if 2" will be enough

[@Wrighty]

+Nochance Man Hi,I run a Blagdon Force Hybrid 16000 Submersible pond pump running on 1.5 inch piping. It pumps around 15000 lph and it's lifting about 4ft (122cm). On using 2 inch pipe I did have to cut the flow down slightly. I have found that 2 1/2 or 3 inch pipework better. Would it be easier for you to add 2 inch pipe along side the 1.5 inch you all ready have. Just a thought.Terry.

Good morning, sir, I'm from Jordan and I saw your beautiful channel. Can you explain to me how to make a mechanical and biological filter and all the thanks and respect for your wonderful person

[@Wrighty]

Hi Mohammed, Thank you for your kind comments. There would be too much to explain here on how to make a proper 3 tub filter system as there are pages of it. If you go to my website: diypondfilters.com and go to the Shop tab and you'll find all the instructions there on how to build a 3 tub filter system from the very start to the finished filter. There's also video's with the instructions showing how things are done. If I can help further just give me a shout on [e-mail] thanks, Terry.

[@ianstockley7250]

Hi Terry/All do you think this system will work with a 100 mm pipe from a bottom drain?

[@Wrighty]

Hi Ian, I have mine running from a 4" (100mm) bottom drain, and reduced to 3" (89mm) to the filter house. I then drop it where it comes out of the ground to 2" (50mm) to the pump. I do this as I think water flows that bit quicker through 3" pipe and less dust settles in the pipe. You can keep it 4" if you wish. A lot will depend on your pond size and the ammount of water flow you'll need through the system as the Midi is on 50mm pipework. If I can help further, just give me a shout on [e-mail] Terry.

How do I stop my filter system from overflowing I got three thousand gallon an hour pump going in on a 1 and 1/2 inch pipe 2 and 1/2 2in pipe going out it keeps overflowing

[@Wrighty]

Hi, your pond pump of 3000 gph is around 11356 ltr per hour. You wont get that flow through 2" pipe. You need to increase your pipe size. Terry.

[@kobudokai1]

@@Wrighty what size pump would you suggest when using 2" pipe pls ?

[@Wrighty]

Hi mate, no more than 8000 lph if it's a submersible and your running twin filter cages. Terry

[@archer1483]

Hey terry...if you wanted to drain each barrell seperately, wouldn't you need a ball valve at each angled pipe?

[@Wrighty]

Hi Stephan, The tubs will only drain down to the bottom of the slots in the filter cages, which is a drop of about 4". Ball valves can be fitted as you can see at point 13:10 in this video: kzbin.info/www/bejne/eXuWp42ClKuYrNU hope this helps, Terry.

Great looking set up. Do you have a rough estimate of how much this type of set up would cost. Obviously depends on where components are sourced, but I would be most grateful. Also I have a 2000 gallon pond with a low stock of fish at a push do you think it would be ok to leave it for a 2 weeks without cleaning just while on holiday? Kind regards

[@Wrighty]

Hi Peter, when I built it, it cost under £140.00. But I would say it will cost more now. I don't know, but I would think around the £200.00 mark. You can get the complete building instruction on my website diypondfilters.com Hope this helps mate, Terry.

[@peterperfect8781]

@@Wrighty Thank you so much for your help. What are you're thoughts on cleaning times.

[@Wrighty]

Hi Peter, Cleaning really depends on your pond, as every pond is different, but I used to clean mine once a week. You only clean barrels 1 and 2, as barrel 3 is self-cleaning.

[@davidharrison8398]

Hello I hope you can advise me. I copied your design and built my own pond filter. All through the winter months my pond has remained crystal clear. The sun has now begun to shine and I have a situation whereby the water leaving my filter is still crystal clear when sampled into a clean glass. However the water in the pond is becoming murky and cloudy. My pond has 2200 gallons of water, 4 large koi carp which I have had for over 20 years and approx 12 to 14 golfish inbred in the pond. I would certainly appreciate any assistance or suggestions that may help. Kindest regards David

[@Wrighty]

Hi David, My first question is do you run a UV clarifying light on the pond? Also what size tubs are you using and what media, plus how much media do you have in each tub? You can contact me on [e-mail] if its easier for you. Terry.

[@davidharrison8398]

Hello Terry Thanks for your speedy reply. I do have a 36 watts UV which I run continuously. In the tubs I have the nylon star wheel type media ( proper name unknown) with 40 lts of 10mm in tub 1, 30 ltts of 10mm and 5mm mix in tub 2 and 40 lts 5mm in tub 3. I would reiterate the water leaving the filter going into the pond is Gin clear. I look forward to hearing from you. kind regards David

[@Wrighty]

It does sound like the sun is producing algae bloom but the UV is not controlling it. When was the last time you changed the bulb in the UV as it does need changing every year. Algae bloom as you will know is caused by the sun and usually green, but as it's only 3 microns in size, its too small for any filter to remove. A UV changes it's DNA so it not only dies but sticks it together making it large enough for a filter to remove. It does sound like the UV is not doing the full job. Hope this helps. Terry.

[@ronszegleti6947]

Ive been doing a lot of research with regards to aeration in the pond. I have noticed on your barrels the lids close relatively tight with no opportunity for the barrels to have air exchange at the top. I have seen this with others videos who use the same type of filtration that you do and their lids also close with no air exchange at the top. It seems to me that your system would greatly benefit with some type of air moving freely at the top, while still keeping critters out. What are your thoughts on this?

[@Wrighty]

+Ron Szegleti Hi Ron, Aeration on the moving bed is not hindered by the lid as the excess air is drawn out with the water to the pond return. I don't see that removing the lid will make any significant improvement to the air supply to the water as the space above the water is getting fresh air from the pump all the time. Thanks for your question. Terry.

[@recklessroges]

Why no swirl filter?

[@Wrighty]

Hi, I didn't feel a vortex was needed on my pond. One could be added quite easily. Terry.

[@barca282]

Hi Terry, I'm a big fan of your filter system and i just have one question: once the 1st barrel fills and starts pouring into the 2nd through the pipes, is the flow/pressure enough to fill the 2nd barrel without overflowing the 1st barrel? cheers chris

[@Wrighty]

Hi Chris, Thank you for your kind comments. They all work well mate. But don't forget this Midi filter is on 2" (50mm) pipework, so your not going to get the same flow through the filter as the Pro Mk2 filter which is on 3" (89mm) pipe. It depends on your pond volume as to what filter you need and also the pump size. I wouldn't go any bigger on a submersible pond pump of around 10,000 lph. Any more than that and the water won't be spending enough time in the filter. Thanks Terry.

[@barca282]

@@Wrighty my pond is around 20,000 - 25,000 ltrs (yes it's big!) my pump is 14,000 lph and planning to use 63mm piping. Hopefully that would be enough. would you also get the same result if all 3 barrels are level?

[@Wrighty]

Hi Mate, I make that 5500 UK gallon. That's too much water for the Midi filter to look after. You need the Pro Mk2 for that pond water volume. I would also recommend the 3" pipework to avoid any problems. Terry.

Hey Terry Armando I have a 2 inch elbow coming out of tub three reduced to 1 1/2 inch hose back to the pond

[@karensteidell9044]

So I should keep it at 2 inch pipe going back to the pond

[@karensteidell9044]

And can you tell me if I need to control valve in where should I put it for the water flow

[@karensteidell9044]

I didn’t see that in the plans that you sent me

[@Wrighty]

Hi Armando, That's your problem mate. The 1.5" is not big enough to take the flow and causing the water to backup in tub 3. The rule of thumb is the gravity outlet should be 2 x the size of the pipe that's pumping in. I would look at a 3" return. Terry.
