Hi Terry. First of all thanks for your video's, I only have a medium size pond with only orfe and goldfish! I was fed up cleaning sponges etc and liked how your system works. I also wanted to see the fish rather than having cloudy water! I have now finished my 3 tubs as yours, and finished it just before i went on a 2 week holiday. May have been best to set it up after i got back as the filters overflowed and my pond emptied! Fortunately my brother in law kept his eye on it and managed to keep the pond filled up :) I just wanted to mention this to you and your viewers as I have just fitted overflow pipes to each tub that bypases the filter media, to enable the water to return to the pond easier. Overall i am very impressed on the clarity of my pond water and love the back washing process. Saves a lot of mucky work, and time. One other thing, I had to put my UV light directly after the pump (before filters) as the flow wasn't sufficient to fill the UV chamber from my last tub and return to the pond! Thanks Gary
Hi Gary, Thank goodness for your brother in law. It's always risky building something new and leaving it. Glad to here all turned out ok. Good to here the filters working well and your pleased with it, Enjoy your pond. Terry.
made these filters about 3.1/2 years ago but kept them all at same level working bang on 1 settlement 3k1 filter 1 moving bed 3000 gallon pond as clear as bath water
Just build the same setup. Have not done a clean out yet as only been running a week and koi are not very active as just out of winter. Must have to give multiple rinses or when you turn the filter back on slightly brown water will go into your pond.
Hi Terry, the first tub is the worst, it is definitely working well, better than any other filter I've used/built, I guess the bottom of my pond is still dirty, so I'll keep at it mate. The vortex brush filter I've added to the waterfall pump supply seems to be working great so I may try one on your design as a pre filter. I will be vacuuming the pond to death in the autumn so that should help. Thanks again for your help..... Barry
I love this filter, my pond is crystal clear and the water quality is great (been running now for 2 months or so) however, I still can't get near leaving the cleaning for a week, 3 days is the most I've been able to leave it so far before the media in bins 1 and 2 is pushed out of the top of the water. Do the more expensive shop brought filters need cleaning this often or is this filter just too efficient!! Keep he videos coming Terry, they are appreciated.
Barry Spiers Hi Barry, Glad all is well. or should I say too well lol. If you're getting dirt like I show in my last video then there working. Are both tub showing equal amount of dirt? you could try more media to cope with the volume. You can go to 60% of your water volume with media. This time of year filters are on overtime. If thing are that bad you could add another tub at the beginning. A swirl tank to pre filter the water and take a lot of the larger particles. Terry.
Hi Rob, the air in tub 3 can be run by a much smaller air pump and the weight of an air stone will hold the air pipe down. Tubs 1 and 2 are just plain pipe (no air stone), so a normal air pipe would float, and you also need a bigger air pump to move the media. You can contact me on pondfilters@gmail.com if you have any problems, I can reply quicker from there mate, Terry.
I love this design. I am planning a small 1000 gallon pond. This design won’t work unless the pond is below the filter level, my filter will be level with the pond and about 50 feet away. Is it possible to pressurize your filter system to push the water back to the pond?
Hi mate, if you have a look at my website diypondfilters.com/shop/ I have a Pro Midi filter that is gravity fed which fits level with the pond with a pump return. With being such a long distance from the pond I would recommend 3" pipework from the pond to the filter to ensure you get enough flow. Terry.
Can’t wait to recreate this set up. Seems to work extremely well. I am curious what air pump your running and what that fancy black control is called that I’m assuming controls your pumps
Hi mate, If it helps there are building plans for my filter on my website diypondfilters.com The box is just a switch box for the pumps and UV. thanks, Terry.
Harry Chung Hi Harry, Yes Yucky filters and the creatures that live in them lol. The fry are doing well. Some are a lot bigger than others. They call them Tobys for some reason, I don't know why. I'm just starting to notice one or two slight differences in them colour wise. It will be interesting to see how they turn out. Take care, Terry.
Hello, The media K1 work very well. Butt I think that U spend too much time & fisical work to clean up the filters. If U Use the same principle of the waste water treatment plant filtration, U need only few mints & low fisical work. It's simple: 1st. stage- conical clarifier filter with drain valve in the bottom, 2nd stage- bubbling air canister with media to enrich the bacterias, & final 3rd stage, another cone clarifier filter with same drainage to clean up and U can add a sponge box biofiltration to add more bacterias. Just drain the 2 clarifiers & save time, water. Anyhow, congrat with Ur pretty pond. Enjoy.
Hi I’m Carla and I have built your set up for my pond. However I am in need of more additional help, I have been working tirelessly on this for a year and I can’t seem to be able to control my pressure. I have too much pressure I believe but my husband disagrees. I can’t have my lids open at all , or I will have over flow. I have change this system so much I have pvc damage parts all over my yard. I upgraded from 3- 35 gallon drum’s to 4- 55 gallon drums. And I still have to divert half the water to keep down the pressure. I have to 2 hp pump external, I am using 2” pvc and it’s still leaking from the lids they look like there going to blow the lids off, what should I do? I think I have 1500 to 2000 gallon of water but not certain because my water meters keep breaking. Ugh overwhelmed with this project!! 🤦🏾♀️🤦🏾♀️ I can send you pictures what’s your email address please can send here
Hi Carla, this is one of my old videos, but you should have ask me way before now, I could have saved you a lot of trouble. Your pond pump is way too big, and your pipework too small. You're not going to get that sort of flow through 2" pipework. Is the 2" the inside or outside pipe diameter? What you have to understand is, you're pump is forcing water through the 2" pipe to the filter. Once the water is in the filter, it is only a gravity flow, so your pipework needs to be at least twice the size of the pump pipework. If your pond is only 2000 gallon (about 10,000 ltr) you only need to have a 5000 lph flow rate for your pond water volume. My email is pondfilters@gmail.com send me some pictures, and I'll help if I can, but I think your going to need a different pump. Terry.
Hi, All the dirt is traped in the media. That's why there is 2 machanical filters. The second catches whatever the first misses And the bacteria eats whats left. Thanks, Terry.
Hi Daniel, thank you. I do a Pro Midi and a Pro Mk2 filter system that can be gravity fed and all tubs are on one level. You'll find them on my website diypondfilters.com any problems give me a shout on pondfilters@gmail.com thanks, Terry.
+Lasantha Nissanke Hi Lasantha, When I first Built the system I did have a swirl tank first, but I found that a static bed caught more dirt. So I changed the first tub to a static bed with slightly larger media. Thanks, Terry.
50f150 I've found pumping clean tap water into the filter while cleaning it kills the bacteria colony. If you do use clean tap water make sure you have an inline dechlorinator/carbon filter attached to your hose or water outlet.
T Kulesa if he could just use the pond water it would work that's how I have mine set up the pump keeps running while the dirty water is flushed out its much like rinse the media off I know that tap water will kill the bacteria
50f150 I think we all understand about tap water but the thing is with the media being two feet deep in the tub, rinsing from the top won't move the dirt on the bottom of the tub with the media sitting on it. The media has to be circulating to get at the dirt on the bottom of the tub. Great input guys. Thanks. Terry.
Hello thanks for the fast response. But I wanted to know about the function of the first two barrels are they supplying your mechanical filtration. Thanks again
Hi Terry as a newbie to ponds , I've just dug a 27000 lt pond , I'm told need to filter this much per hr would I get the flow rate through this system? Steve
Hi Steve, For 27,000 ltr this filter would not be big enough. You need to look at moving around 8,000 lph through the system. You would need either the Pro filter, if your going to be pump fed, or the Pro Mk2 filter, if you're going to be gravity fed, Here's a video of the Pro filter, ruclips.net/video/b4T8TkRTXAo/видео.htmlsi=8IFi2pkWH74ueqg8 the difference is with the Pro Mk2 all the barrels are on one level, and for the turnover you're looking for, you would need to use 3" to 4" pipework, to and through the filter. Hope this helps mate, Terry.
This might be a stupid question but when you turn the pump off to clean the first drum, does the water not travel back down to the pump as it's bottom fed?
Hi terry just found your videos/filter and think there great. Im currently designing my first koi pond and wondered if this type of system can be used for a raised pond for a gravity fed bottom drain?
Hi Leason, The best filter for a gravity fed system is my new Pro Mk2 filter. You can build that one with all the barrels on the same level for gravity fed systems. Hope this helps. Just give me a shout on pondfilters@gmail.com if I can help further. Terry.
Hi mate, This filter was built way before the Tempest existed. It's very similar to the way the mechanical filters work in the EA Nexus filters, but these do perform better, as there's 2 mechanical filters. Hope this helps. Terry.
@@Wrighty I think they stole your idea and then made it more compact. Haha Are you still using this kind of setup? I've been umming & arring about what filter to build for a while now, I'm thinking of using this design but also including a barrel of Alfagrog at the end and maybe doing it gravity fed with air-lift return although I'm not sure if it would provide enough flow rate.
Lol, you never know mate . 🤣🤣 I don't use this system any more, as I built my own RDF. If you've not seen my filter house, have a look at this video, you can see most of it, and everything in it is home made ruclips.net/video/ZcqQvEQ_X4g/видео.html take care, Terry.
Peter Frans Hi Peter, I run a Blagdon Force Hybrid 16000 submersible. It pumps 15000 lph less head pressure. My air pump for cleaning pumps 33 lpm. The pump on my skimmer that goes straight back to the pond pumps 7000 lph Hope this helps. Check out my website for more info: diypondfilters.com Terry.
Hi,I use a complete water test kit as TDS can be general. I have not had a problem now the filter is mature. I did have above average nitrate readings as the filter is so efficient at clearing Ammonia and Nitrite, But since adding pond plants and lilies that reads ok. I do water changes when I clean the filters, every week or week and a half.Terry.
+Wrighty tds measure the hardness and softness of the water. I read on many articles saying soft water is the best to go for skin and growth. Try testing for tds after one week of running your filter. I am really curious to know. Thank you Suwarko
your first project (the mother of K1) had overflow piping included - these dont - why not? What if something actually get clogged? where's the water going then?
Hi, This system was more of an experiment. I'd been ask so many times if 2 inch pipework could be used with this filter, so I built one. As it wasn't going to be on my pond too long (as I wanted to build a bigger system) I didn't bother with overflows. There so easy to fit and like you say I did show them on my last filter. You are correct, overflows will give peace of mind. Terry.
What sized barrols did u use on this smaller version? - Looks hell cleaner compared to your earlier one(s) - but think it could be made looking even cleaner by putting most pipes on the back facing the wall - air controls could be fed into once vertical line on the short end to gain access to the on/off turn knobs - the only thing that would be visible @ front would be the drain pipes - just a thought - Im looking at building something like this, but my main problem is how to minimize the foot print and make the barrols not to stand out (not enough room to build a box around them - also need these barrols to be at the edge of my garden bed that is being watered with sprinklers all the time - so its a problem for me - good project that I like though (Even though the cost of K1 media and all these fittings, air blower, UV light etc etc would mean a pretty hefty price @ the end of the day - but I guess getting a pond clear comes @ a price ;)
The barrels I used here are 110 ltr tubs. Have you seen the new design on this system. ruclips.net/video/b4T8TkRTXAo/видео.html You can find out more on my website diypondfilters.com
Yea, that looks heaps cleaner - is your drainage underneath now or doe these pipes wrap around to the back side? - and the connections between your barrels, do I see a valve in between or... Difficult yo make out from your video.
+steve187 Hi Steve, Sorry I've not answered only RUclips's not letting me know when I have comments. Mainly just the first two, but I do give the moving bed a wipe round with a brush every now and then. Terry.

Hi Daryl, thank you. You can get the full filter build plans for this filter on my website diypondfilters.com if it helps. Terry.
Maybe leaving the pump on if it's being feed from the bottom and closing the outlet to the next drum

Hi Terry. Why are the first two barrels fed via 15mm speed fit for air source yet barrel 3 is only normal air line hose ?
Thanks Terry

A larger air pump would work great for the clean out
50f150 The problem was I had too much media in there. I just guessed when putting it in. It works perfect now.
Terry.
If everyone cleaned their filter media like you, we wouldn't have any water left to drink. Use smaller bead media and only rinse your median one time
Anyone who keeps a koi pond correctly changes 10% of their water volume every week. This is counted as part of it.

Whats stopping the brown water going back into the pond while the system is running during the week. The media traps it?
Hi, All the dirt is traped in the media. That's why there is 2 machanical filters. The second catches whatever the first misses And the bacteria eats whats left. Thanks, Terry.
Hi brilliant filter. Is it possible for these to be ground level and gravity fed and pump to return the water thanks
Hi Daniel, thank you. I do a Pro Midi and a Pro Mk2 filter system that can be gravity fed and all tubs are on one level. You'll find them on my website diypondfilters.com any problems give me a shout on pondfilters@gmail.com thanks, Terry.

Thank you, Terry.
Hey. You should add a swirl filter prior to the first filter.
+Lasantha Nissanke
Hi Lasantha,
When I first Built the system I did have a swirl tank first, but I found that a static bed caught more dirt. So I changed the first tub to a static bed with slightly larger media. Thanks,
Terry.
If there was a way to pump clean water while draining the dirty water out you might only need to do it once . But it is a nice setup
50f150 Thank you. There is something like that coming up in my next video. Can't say to much at the moment.
Terry.
50f150 I've found pumping clean tap water into the filter while cleaning it kills the bacteria colony. If you do use clean tap water make sure you have an inline dechlorinator/carbon filter attached to your hose or water outlet.
T Kulesa Hi, You're correct, I would never use tap water but I have something else in mind.
Thanks for your input.

hi how do I setup the exit pipe. I set up the exit pipe at side of the barrell eith a net and all the k1 clogs the exit
The water exits tub 3 through the filter cages, the same as the other tubs. Terry.
Hello thanks for the fast response. But I wanted to know about the function of the first two barrels are they supplying your mechanical filtration. Thanks again
The first two tubs are static media and are the mechanical filtration of the system. Terry.

Hello can I ask are the first two barrels with K3 being used for mechanical filtration and third barrel for biological. Thanks
You'll find the K3 a bit on the big side. You can try K3 in tub 1, and K1 in tub 2. Most have the K1 in tub 1 and K1 Micro in tub 2. Terry.

Just a quick question, how high is your TDS reading? and how frequent change of water?
Thank you

Where does the drain go to? I really wanna know.
Hi, Mostly on my garden unless I'm doing a video, then I can't do both so it goes down the drain.. Terry
Pour that water on your plants an watch them take off on my aquariums I always water plants with the water

What sized barrols did u use on this smaller version? - Looks hell cleaner compared to your earlier one(s) - but think it could be made looking even cleaner by putting most pipes on the back facing the wall - air controls could be fed into once vertical line on the short end to gain access to the on/off turn knobs - the only thing that would be visible @ front would be the drain pipes - just a thought - Im looking at building something like this, but my main problem is how to minimize the foot print and make the barrols not to stand out (not enough room to build a box around them - also need these barrols to be at the edge of my garden bed that is being watered with sprinklers all the time - so its a problem for me - good project that I like though (Even though the cost of K1 media and all these fittings, air blower, UV light etc etc would mean a pretty hefty price @ the end of the day - but I guess getting a pond clear comes @ a price ;)
The barrels I used here are 110 ltr tubs. Have you seen the new design on this system. ruclips.net/video/b4T8TkRTXAo/видео.html
You can find out more on my website diypondfilters.com
Yea, that looks heaps cleaner - is your drainage underneath now or doe these pipes wrap around to the back side? - and the connections between your barrels, do I see a valve in between or... Difficult yo make out from your video.
all the air pipes and drainage is now on the bottom of the tubs. I have put 3 inch gate valves between each tub, but these are optional.
hi, you clean all three barrels, or only the first two? :)
+steve187 Hi Steve, Sorry I've not answered only RUclips's not letting me know when I have comments.
Mainly just the first two, but I do give the moving bed a wipe round with a brush every now and then.
Terry.
Thanx :)
