Love my midi system you designed but been really interested in a rdf just the price to buy is pretty ridiculous plus I'd rather build one myself ( from your plans) so I better understand the working of it
Hi Sam, That's what has taken me so long with the build. I could only use what is readily available for everybody. So I have put a lot of time into this so everyone can get the parts. A new one this size is £3500.00 and I'm hoping to keep this under £500.00. That's if you buy all the parts. There is so many ways you can cut down on that £500.00 it's untrue. Thanks, Terry
Wrighty looking forward to see how it gets on and buying the plans to build my own most the chaps and the koi club I go to either have rdf or other big expensive filters and they can believe how your midi system I made can keep up with them they'd never heard of your plans/systems can't wait mate I'll keep everything crossed for your testing cheers and good luck
Hi Sam, I'm hoping to have the video of the first run out within a couple of weeks, so it's fingers crossed mate. I'm working on the electrics at the moment. Thanks, Terry.
As always Terry an excellent video your pond and yard look great. Workmanship is top-notch as usual. Thanks for posting you do inspirer me to do better with my pond.
Pond is looking good! and the things men get up to in there shed! You've created a monster! nice job well done very interesting. waiting for the up and running video keep ponding.
You surprise me every time mate, bloody brilliant on building the drum filter hope you release the building on your website like the others you can buy, spot on mate
Thanks Richard. I must admit there has been a bit of trial and error, but I think I've cracked it now. Can't wait to connect it up. I have to give it a good test, but will release the plans asap. Terry.
Just wanted to let you know my filter system is doing very well.I just flush it once a week and my water is clear enough for my 92 yr. old mom to see the fish. Thank you for your advice and videos! The k1 barrels and gravity feed system works.
Hi Terry, hope you’re well, May I ask if you ever did a video on how to build the RDF drum itself please? Would like to know what materials you used? Thank you kindly Tony
I've been looking into theze drum filters myself. very pricey. but I believe they are tge best out there for what tgey get out, and maintenance. Don't think I could make my own, think I would have to buy one. Can't wait to see yours up and running. Great video as always. love the new net, much better. Happy ponding.
Hi Ron, Hope your well. I will release the building plans when I've got them done. It's not too hard to build. Also I got video of every step. Thanks, Terry.
Hi Wrighty,Another brilliant DIY job.Can you advise which float switch you used as am looking for one to control my pump in the last chamber if my pre filter blocks. I am wanting one that can control a level between 25-75mm and mains voltage. The ones I have seen are low DC.
Terry loved watching all your videos just this year taken up looking after koi Question please what pond paint did you use on the original RDF and Moving bed Your thoughts would be much appreciated Michael
Hi Andrew, I've still got a bit of testing to do yet and have not worked out the cost yet. The thing is I have bought everything new. There's so many things you could save money on when building it will bring the cost right down. I should have results within the next 2 weeks. I will release the build plans on my website diypondfilters.com Terry.
i have a small discus hatchery and use a swimming pool filter which works very well . i find it fascinating to look at some of the filtration systems you pond guys use . my question is why not use a pool filter with silica sand in it ? i never see this with pond filters , so there probably is a reason for that ?
Hi Mate, It would take me a while to explain here so I have a link for you which will make things easier: www.happykoi.co.za/filters/advanced/sand_filters.htm Hope this helps. Terry.
thanks this made for an interesting read . i think the difference is that ponds have a lot more detritus going through their system . the article mentions several times that the sand becomes so cloged that it creates anaerobic pockets i guess i never experienced that because the water is already pe-filtered by filter floss in my system and since discus need big water changes it gets back washed every day at least once sometimes more than once . i like your video's although i don't have a pond myself ,.... cheers !!!!
Nice one Wrighty, glad it's going well. The fun you can have with a lettuce huh :) Be waiting to see how the RDF works. Must admit I preferred the old intro and exit music though :( sad to see it go.
Okay thanks Terry! Its what they call "liquid liner" The grey color just confused me :) Hope it all works well in the long run and thanks for your videos.
Hi Kevin, I'm sorry for the late reply mate, only I'm not getting notifications on posts from UA-cam. This is the pond paint I use: www.ebay.co.uk/itm/Epoxy-Resin-Pond-Paint-For-waterproofing-damproofing-ponds-and-water-features/191089386745?hash=item2c7dd0a4f9:m:mVD4QJ8Wte6VgVVtEz6d7Pw:rk:2:pf:1&frcectupt=true Thanks Terry.
Hi there weighty can you let me know what gallon pond does this handle? I'm gonna crack on with my own as I cannot for the life of me. Fork out £ 3000 + . I cannot see it out working your moving bed filter. I've the same barrel system thanks to your inspiration. THANKYOU Allan
The 3 tub system gives great filtration. I want to know if this system is as good. It certainly won't replace the 3 tub system. there a lot harder to build for a start. Terry.
Bloody hell terry, is there anything you cant build :) cant wait to see that up and running, if it runs as good as you hope will you wave bye bye to your current system? does it work as a sieve? or is it responsible for building the bacteria too thats needed to clean your pond water? Unreal Job Mate really cant wait for next Video Takecare Bud Kev :)
Hi Kev and thanks mate. I thought when I was up-loading the video. kev's wife won't like this lol. It's a sieve and a filter. It will still need a moving bed for the bacteria. But this is suppose to take the finer rubbish as well. The more it blocks the more finer particles it catches. It's up against the Pro system so it has to be bloody good to beat that mate. I will video everything when first turning it on for everyone to see. Must say I'm a bit excited with it. Terry.
No mate, I think I missed my vocation in life lol. It's toooo late for me now lol. The biggest problem was finding things for the build everyone can buy easily. Had a few sleepless nights :) and the wife thought I'd left her lol. Hoping I've cracked it now though mate. Hoping to have the working video out in about 2 weeks. Terry.
Hi Terry Just came across a product on Amazon in the US. And as I can't get cloverleaf in the U.S., I am always on the look out for alternatives if you would please check out Nualgi. Don't know if you can get in the UK But look promising if the product works. As finding something that works like cloverleaf in the us is rather hard.
Hi Robert, Just had this posted on one of the other video's. Have a read and see what you think. Hi Terry, I used 0,3 gram zinkoxide for 1000l water. My pond is 7000l so i put 2,1gram in 10l warm water. I mixed the water and the zinkoxide and then i put it in the pond. For safety reasons i spread the cure over 2 days. So 1,05 gram each day. The next day the algue already went smaller. And now most of the algue is gone and is in the filter. The main ingredient of cloverleaf blanket answer is just zinkoxide. You can buy it for less then a few dollars in the pharmacy. Don't waste your money on algue away goods. Also the zinkoxide didn't make my water milky. Use it at your own risk, but for me it worked wonderful!
Hi llamedos R, Not to worry. I have loads of people wanting me to build them a pro system. You'll sell it dead easy. You can put it on my website under the FOR SALE tab. I would hang on a bit until I have given it a good testing. I want to know if it's as good as the Pro filter first. Thanks, Terry.
You should add a UV sterilizer on the outside of the drum. I have seen others do this, and it keeps the inside looking almost brand new, without them it will start to grow algae and get mucked up eventually. Looks awesome, can't wait to see it up and running! Here's a link to a vid where he shows running an rdf with and without a UV light. ua-cam.com/video/Zcb7t5RBEWw/v-deo.html
That's true. I have been looking into them but they are very expensive. I just want to get it up and running for now but will look into it. Thanks Terry.

Is your one made of wood? I have some 12mm polypropylene sheet stashed away from work I can make the box out of
Hi Sam, Yes I made it out of 18mm best ply. Terry
Wrighty looking forward to see how it gets on and buying the plans to build my own most the chaps and the koi club I go to either have rdf or other big expensive filters and they can believe how your midi system I made can keep up with them they'd never heard of your plans/systems can't wait mate I'll keep everything crossed for your testing cheers and good luck

Thanks Matthew, I know, I can't wait to get some water flowing through it to see how it does. Terry.
You surprise me every time mate, bloody brilliant on building the drum filter hope you release the building on your website like the others you can buy, spot on mate

ponds looking great
Thanks Joe.

Hi Ron, Hope your well. I will release the building plans when I've got them done. It's not too hard to build. Also I got video of every step. Thanks, Terry.
looks like a pro model. Nice Job
Thanks Robert, I hope it works as well lol. It's got the Pro filter to beat on performance first and that will take some doing. Thanks, Terry.
Hi Wrighty,Another brilliant DIY job.Can you advise which float switch you used as am looking for one to control my pump in the last chamber if my pre filter blocks. I am wanting one that can control a level between 25-75mm and mains voltage. The ones I have seen are low DC.
Hi and thank you, sorry, but the ones I'm using are the low DC voltage ones. I got them on ebay. They just trigger a relay. Terry.
Terry loved watching all your videos just this year taken up looking after koi
Question please what pond paint did you use on the original RDF and Moving bed
Your thoughts would be much appreciated
Michael
Hi Michael, I've sent you an email mate, Terry.
wrighty how much would your rdf cost to make as i quiet fancy having one on my pond once you have it installed
Hi Andrew, I've still got a bit of testing to do yet and have not worked out the cost yet. The thing is I have bought everything new. There's so many things you could save money on when building it will bring the cost right down. I should have results within the next 2 weeks.

Hi, I thought it would be easier than me trying to explain. Glad it helped, thanks, Terry.
Nice one Wrighty, glad it's going well. The fun you can have with a lettuce huh :) Be waiting to see how the RDF works. Must admit I preferred the old intro and exit music though :( sad to see it go.
Thanks mate. I'm with you, I might bring it back. Terry.
Hurray :) Hope so
Brilliant!
Are you going to post the plans / parts list? :) And is that box made entrirely by wood? How did you seal that?
Hi, Yes, I will have plans out before too long, once I know everything is ok with it. Yes it's all wood sealed with pond paint. Thanks, Terry
Okay thanks Terry! Its what they call "liquid liner" The grey color just confused me :) Hope it all works well in the long run and thanks for your videos.
Hi Terry what paint did you use on the RDF and moving bed filter
Hi Kevin, I'm sorry for the late reply mate, only I'm not getting notifications on posts from UA-cam.

Hi, Great video. In the vid you show and comment about your pump. Which make is it please.
Hi Paul, My pump is a Mega SS20. 8000 lph. www.absolute-koi.com/prod1757.html hope this helps. Terry.
Do you have any idea how to control algae naturally !!
Thank you for your new video 👍
Hi muj2912, You can try Barley Extract. I used it but I found out my water was too cold for it to work. Thank you, Terry
Thank you very much I will try it
Bloody hell terry, is there anything you cant build :) cant wait to see that up and running, if it runs as good as you hope will you wave bye bye to your current system? does it work as a sieve? or is it responsible for building the bacteria too thats needed to clean your pond water?

Fantastic mate cant wait for this, you must of been an engineer or something of that profession? your work is so neat and well thought through :)

hi would like to know how you made it cheers
Hi Ken, Once it's all tried and tested, I will release plans on my website diypondfilters.com Thanks, Terry.

bugger. i just built your pro filter. now i need one of these

I would hang on a bit until I have given it a good testing. I want to know if it's as good as the Pro filter first. Thanks, Terry.
What is "Huvered it out" mean?
Sorry. It means I used my pond vac to clean the pond. Terry.
Video not loading
Hi Jim, Have you tried another browser. I'm not sure what's causing that mate. Terry.
Wrighty Terry tried the video again and it worked. Pond looks great . Very nice work on the RDF my friend looks great.
Thanks Jim. Glad you got it working mate. I just hope the RDF works as well as it looks lol. Thanks, Terry.

That's true. I have been looking into them but they are very expensive. I just want to get it up and running for now but will look into it. Thanks Terry.
Adam Julyan has good video of it.
Hi Tom, yes, I have seen it. Its a bacteria build up. I think those that use tap water don't get that problem. I will look into it. Thanks, Terry.
