Hi Chris and thank you, I will do plans once I know everything is ok with it. I haven't worked out the cost as yet but the thing is with this filter, there are a lot of parts where you can save money. Thanks, Terry.

Wrighty thanks buddy. Keep me posted. I think you could be onto a winner with this one. 😀

Any developments Terry with this RDF? Itching to see how it's going. 😀

Hi Chris, The RDF is on my pond as we speak, and has been running for just a week. I have to say it's going better than I ever imagined. I did have a bit of a disaster for a start. I moved my Pro system on to my patio and set it running so I could run it while I re-plumbed the shed for the rdf. I got the moving bed installed and then the rdf which took about a week. I think I must have got a bit excited about turning the rdf on lol. When I was ready for the big turn on, I just turned off the pump to the Pro system, went in the shed and turned on the rdf. I must have stood watching the rdf for about 30 minutes. All was fine. Went to look at the pond and I couldn't see my fish. I've never seen my pond so dirty, and for a few seconds I couldn't work out what the hell had happened. Then it dawned on me. I just switched the Pro filter off, not thinking that I had no one way valve on the Pro filter, so it emptied all the dirt it had caught in just over a week back in to my pond. It took about 5 days and my pond is back to normal again. So I really put the rdf through its paces lol. I was a bit apprehensive as to whether it would be as good as the Pro system as that does take some beating. But as of this moment, it is defernatly on a level with the Pro system in performance. The bonus is, the dirt it catches is removed straight away whereas with the Pro and other filters, it sits in the filter for a week still polluting the water. Also I have no filters or media to clean now. There are a couple of things I want to change but there only minor things. I have to say I'm well impressed. Terry.

I think it's outstanding the way you've made it from scratch. Your right about the drum removing the waste straight away. Are you going to run the drum leading into a moving bed? Or run it from drum into your pro system to increase filtration? Look forward to your next video buddy. 😀

Thanks Jim, the test went better than I imagined. Thank, Terry

Thanks Andrew, I did have one or two headaches but got there in the end. Thanks again, Terry.

Thank you Jon Jon, very much appreciated, Have you seen the new video. Released tonight kzfaq.info/get/bejne/j66BodBl0dmrlXU.html Terry.

Thank you Angela. Very much appreciated. Terry.

Hi Chris and thank you, very much appreciated. I will try to put a small video together as everybody is waiting for one. The thing is, as always I want this filter the best it can be before I release the plans. The mechanics of the rdf are spot on and ready to go. I just want to try an even finer mesh than I'm using now to be sure we've got the best. Trouble is its £75.00 a go lol. Anyway I have ordered finer mesh so as soon as I've given that a go I will release the plans. Thanks again, Terry.

Hi Orfeyo, thank you. I will get the plans out asap but there is quite a lot to do. Thanks again, Terry.

Hi Jack, and thank you for your kind comments. This is quite an old video. I now have a new version of the RDF made using polypropylene for the case. You can see it in this video: kzfaq.info/get/bejne/rdRkhblo3cimaI0.html thanks again, Terry.

Thank you, very much appreciated. Terry.

Hi, and thank you. I do have a newer version of the DIY RDF you'll see in my newer videos and can find on my website diypondfilters.com hope this helps, Terry.

Although I did miss the "happy ponding" at the end 😂

Thank mate, very much appreciated. Glad you like it. sorry I forgot :( Terry.

Hi William, Thank you. It really looks promising, but I have to say "it's really got to go some to beat the Pro filter. Thanks again, Terry.

Hi Mark. Thank you, very much appreciated. Terry.

Your very welcome mate.

Hi RORY01014, That's a good idea. I was messing about yesterday trying to put a T on the inflow to stop the dirt from settling. I haven't tried it as a gravity fed filter, but I see no reason why it wouldn't work. Thanks mate, Terry

I hope it helps! I imagine gravity fed the water would be set so that it is just under the guttering, and the float switch would trigger if the water level drops on the clean side of the drum. Maybe I will be the Guinea pig for it! :) Looking forward to seeing the plans and a rough build cost, hopefully I can then downsize it slightly and give it a go!

Hi mate, I would just have the water level in the filter equal to the water level of the pond and pump from the clean water side. I would have a check valve in the pipe to the filter so you were able to turn the water off if needed. Terry.

Sorry that's what I meant, (the drum's height would be set so the water level (pond level) is under the gutter and you would have the normal slide or ball valve on the inlet and it then feeding a bio chamber of some description and have the pump after that :) Basically it would be a combi drum. The possibilities are endless! Very excited to get started now Thanks Rory

Hi Richard. thanks mate, very much appreciated. Terry.

Thank you. Terry.

Thanks Martyn, glad you like it. Terry.

Hi Simon, This does take a lot more making. You will love the Midi system. I still love my Pro system and if this doesn't give me the water quality I'm use to the Pro will be back. Thanks, Terry. PS. The Midi system will always sell if you decided to.

I do love the midi system! Water is crystal clear, parameters are spot on and maintenance is easy! Cheers!

Hi Mate, would you give your wife my most humble apology. I did the video at 1am this morning so I was a bit tired. thanks for your kind comments. I have the float trigger set pretty low at the moment for testing, but if I lift it slightly and stop stirring my pond up lol, I would think it will go around 3+ hours between cleans. I have it set for the drum to do two revolutions which is 15 seconds. thanks mate, Terry.

Hi Dayan, Thank you. Have you seen the build of my new Polypropylene RDF. This is the first run I had with it: kzfaq.info/get/bejne/rdRkhblo3cimaI0.html thanks, Terry.

Hi Chris L 123cm x W 63cm x H 70cm hope this helps mate. Terry.

Thanks Matthew, very much appreciated. Terry.

Hi mate, I actually built a Mk2 RDF which was made out of 6mm Polly Propylene. Have a look at this video: kzfaq.info/get/bejne/h-CBqbaryOCuoqs.htmlsi=Vsn-y7Fa35C91pGr There are many other videos showing the RDF on my channel. I just used a Triggered Timer Delay switch for the drum cleaning control. Hope this helps. Terry.

Hi. Thanks I have watched many of your vids now. Do you have a direct contact email? I have so many questions. lol.

Thanks mate, it's appreciated, Terry.

Hi Shane, Thank you for your nice comments and input. That's good thinking. I have thought about it, but I don't think you would generate enough power from the jets to move the drum. When the drum is half submerged in water it does take quite a bit of turning. Plus as it turns it has to lift the wet dirt out of the water and round to the top. That's one of the reasons I went for a wiper motor, as they've got quite a lot of torque for a small motor. Thanks again for the input. If you think of anything else give me a shout. I love to listen to ideas. Terry.

Hi Jeff, and thank you 👍👍 You can see my latest RDF I built in this video: kzfaq.info/get/bejne/rayVlKljqp2RpZ8.html thanks again mate, Terry.

Hi Brian, You can find all the info for the RDF on my website in the Shop. diypondfilters.com Terry.

Hi, and thank you. The case is made from 18mm ply, and the mesh was 70 micron. I have a new one since then, I'm in the process of working on at the moment: kzfaq.info/get/bejne/rdRkhblo3cimaI0.html Terry.

Can I buy the plans ? I understand if you want to keep them in your back pocket wrighty. But I'm well impressed.

Hi Alan, thank you, very much appreciated. I must confess I'm no carpenter or painter lol. I just scrape by, ask the wife lol. I think you'd be looking at £3000.00+ for one this size retail, so I have saved a few shillings. Thanks, Terry.

Once I'm happy everything is running as it should and I get the plans drawn up, yes they will be on my website mate. Terry.

Hi Nigel, Thank you. During the build of all these filters I bought a job lot of fittings which I'm trying to use up. Most of the 50mm have been used now but I still have quite a few 40mm left. I am at this moment looking at UV's for the rdf but the price is a bit scary as it's quite a long drum in this one lol. But I will keep looking. Thanks, Terry.

Thanks Tony, that's the good thing about an RDF, you can put what flow you want through it. I have it on my pond now with an 8000 lph inline pump. Workes really well. Terry.

Thank you for your kind comment. Terry.

Hi Imam, I used a 150w water booster pump. you can get them on eBay. Terry.

Hi mate, and thank you. Good to hear you enjoy the videos and thanks for the 👍👍👍. Have you seen the newer version of the RDF I made? It's been running on my pond now for over 2 years, and not been a problem at all. Have a look and see what you think: kzfaq.info/get/bejne/rdRkhblo3cimaI0.html take care mate, Terry.

@@Wrighty cheers Terry I’ll take a look at it 👍🏻 I’ve bought a Burtons Drum recently and I’ve had to show everyone on my Channel it’s faults… should of built my own like you 🤷🏼‍♂️🙄 we live and learn!

Hi Andre, The main part to find would be the drum ends. You can use 450mm drain pipe if you have it there. The rest is washing machine parts and a wiper motor. I bought everything new and it cost me £550.00. This was the next video: kzfaq.info/get/bejne/j66BodBl0dmrlXU.html Terry.

Hi Richard, thank you. you can get the build plans for this RDF and the New PP RDF on my website diypondfilters.com If I can help further just give me a shout. Terry.

Hi Lee, It's competing with the Pro system at the minute so it's got to be good. Thanks, Terry.

Hi Mate, yes I'm going to build another box just for a moving bed. I'm reluctant to take the Pro system apart just for the moving bed. Terry.

Hi Harry and thank you. Yes I will put the plans on my website in time, once I know it's ok. I hope it's not her best jug or I'm in big trouble lol, Thanks, Terry.

Hello mate, thanks for your kind comments. No I'm afraid not. I don't know anything about them. I remember them flying over years ago. very impressive aircraft. Thanks, Terry.

Wrighty ok lol. Just recognised your intro music from the the vulcan hanger tour lol.

Hi Brad, it will be a while as there's a heck of a lot to explain. But once I know it's ok I will get stuck in to the plans. Thanks, Terry.

Thanks for the reply. I already have a set of your barrel plans and should have it up and running on my next off days. I really enjoy your videos.

Hi Rory, The drum filter has been running on my pond for a week and a half now and have to say it's not put a foot wrong. I am in the process of building the plans at the moment and there is a lot to get down plus all the videos. I'm at over 30 pages now but getting there. There are still a couple of things I want to change before I release them, so I'll get them done first. I will post it on my website when I have released them so everybody knows. Thanks, Terry.

Wrighty Thanks for the quick reply, and thanks for the effort you put in! I look forward to videos and the plans Rory

I've only seen these radial filters in videos, and don't have one myself. However, I do know that drip irrigation filters use 200 mesh. I would guess that a pond would use the same or even wider than a filter for "tap water." I would guess something closer to 400 would still be plenty fine

I have a 350m. stainless steel and have to tell you the tap water does not go through if don't pressurize it. And in my case it is gravity system. So I had to reduce to 100. Now, every time I need to clean I am using pressure washer :) Other then that I am very happy. I just put the mesh under angle and let the water go by. Will have to take some time to take a video.

oh wow I must be confused. I was under the impression that the mesh number referred to microns. meaning a higher number is more open and "free flowing"

no, the mesh is like pixels. Number of holes in 1 square inch (if I am not wrong) :D

You need to install a uv light that will stop the biofilm from building up and clogging the screen

Hi Dennis, Thank you. Hope your well mate. This is the time of year for spawning, especially now the pond water has warmed up. spawning mats and mops can be made of many things. You can buy spawning mats and brushes. Your best bet is to have a look here on KZfaq, there's loads of ideas here. The main thing is your water quality, it has to be good for them to spawn. When they start spawning it can be very early morning, maybe still dark. Trouble is once they start spawning, the others will start to eat the eggs and they will eat them there selves if left. So don't be too long in getting the eggs out if you want to keep them. Just make sure whatever you use is fish safe and not been in contact with any chemicals. Hope this helps mate.

yeh i been watching vids on here how to make something out of yarn but was looking on ebay and see the brushes 4 for 30 quid and they big i will probly end up getting them it was aughust when they spawned last year but if i get the brushes now would it be ok to leave them in for 2 /3 months if it comes to it it would be ok init cheres mate

Hi Dennis, I have never used the brushes myself, but I don't see a problem with leaving them in the pond. If they got dirty you could just whip them out and hose them down. Terry.

Hi mate, I have thought about this but the actual spray is quite fine and not powerful enough to move the drum. Thanks, Terry.

Hi Kev, Thanks mate. I used a very expensive 2 pack pond paint. But I must say it seems really good. It is fish safe but due to the cost of it, I only did all on the inside of the filter box. The outside is normal paint. It has got to go some if it's going to be better than the Pro system. But only time will tell. Thanks mate, Terry.

Thanks Terry, glad its running well you hard work has paid off yet again :)

I must admit I do love my Pro system. It's not put a foot wrong in 2 years and always given me fantastic water. But then this filter does look really good and has one or two improvements on the Pro system. There's no cleaning for a start, and also the captured dirt instantly goes out of the filtration system and does not sit in it for days like the Pro. If I don't get the gin clear water like I have with the Pro I will bring the Pro back. Thanks Richard, Terry.

Hi kb698, Yes it can all be adjusted. The time between cleaning and the amount of rotation. Thanks, Terry.

Hi Chris, did you want the size of the filter box or the total length including pumps motors and pipes?

Thank you, There's not room for the two of them in the shed and I want to keep the Pro together as a system as it's a really good filter. so I'm going to build another box for the moving bed. Thanks, Terry.

I'm as we speak doing the plans and cost at the same time. There's quite a lot of video work, but I will get it done as soon as possible mate. I want to be sure everything works as it should. Terry.

Hi Gaz, drop me an email. pondfilters@gmail.com

Hi, I've not yet worked out the cost as I'm still tinkering around with it. but I must admit I am very pleased with it as I expected more teething problems than I got as there's quite a lot of mechanics involved. I don't get much dirt settle in the first chamber now as I have a small aquarium air pump and a couple of air stones both sides to keep the dirt from settling. Thanks for the input. Terry.

Hi Paul, A good manufactured RDF this size would cost around £2000 upwards. They do make different size. I have a newer RDF version out now. You can see it in this video kzfaq.info/get/bejne/sKuTnq-etd3Nn4E.html Terry.

Hi Jack, and thank you. I don't build these RDF's to sell unfortunately mate, But I do have a newer version of the RDF out now you will find here: kzfaq.info/get/bejne/rdRkhblo3cimaI0.html You can get the complete DIY RDF building plans and instructions for it on my website diypondfilters.com This new RDF is built using Polypropylene PVC instead of 3/4 ply as used in the original one. Hope this helps mate, Terry.

Hi David, sorry but I just don't have time mate. The plans to build one are on my website diypondfilters.com thanks, Terry.

Hi Robert, I've got to make a moving bed to suit the drum filter, I really can't break up the Pro system, It's a cracking filter. Anyway, if this doesn't give me gin clear water like the Pro did, the Pro will be coming back lol. The plans will be in feet and inches and metric. Thanks, Terry.

Hi and thank you. couldn't say too much incase it didn't work lol. Terry.

hehe, yes your are right.. I dont think it is the problem about making the setup, but making the axel watertight would be a small puzzle for me to do, sekond, I have no clue about electonic, so that would require help, if I had to build one

Water proofing was not a problem, and if I can do the electrics, anybody can. I've kept them really simple. All will be explained in the plans when I get them released. Terry.

might be true, there isnt much to the filter build, other than being able to messure and cut the stuff in the the right sizes, and that is really not an issue for me.. but at the moment I do not have time to focus on a build like this for the time it take to make one.. maybe one day Ill do on, unless I figure out how to make a more cleaver setup.. yet, I dont think there are many filters that can out perform the drum filter.. - yet, if you want a crystal clear lake, I think adding a papir roll filter after the drum would be an awesome combination..

I'll have my moving bed after the drum as its essential to deal with the ammonia and nitrite.

Hi Bernie, I can't resist a challenge lol. I won't run both, but it has got to be good to replace the Pro system. I am going to give it a try on the pond and see how it goes. I have had to build a moving bed to go with it so were down to 2 tubs lol. I have to say it worked better than I ever imagined and it's the fact that none of the dirt stays in the filter like all other filters and it's self cleaning. I do love my Pro system though so it's going to be a hard decision. Terry.

I understand your dilemma. I thought that maybe it would go before the pro system giving you a double whammy so to speak????

I don't have the room, but the RDF is a filter on it's own and should do what the Pro does if I've got it right. Terry.

Hi Kev, I got it on ebay but it's well expensive. £30 a ltr. www.ebay.co.uk/itm/191089386745?_trksid=p2057872.m2749.l2648&var=490284044508&ssPageName=STRK%3AMEBIDX%3AIT

Thank you Terry much appreciated

Hi David, I used a car window wiper motor. Terry.

@@Wrighty Thanks Terry. Are you prepared to reveal the brand as I find recommendations are best.

Hi mate, I've just had a look for you but there's no name on it, and the eBay link no longer works. I got it on eBay and it was a front screen wiper motor to fit a VW Golf if that helps. Terry.

@@Wrighty Many thanks Terry. That gives me something to work with. Having only recently seen your drum filter, I think it’s superb!

Hi David, I do have a newer version of the RDF out, made using Polypropylene instead of the ply. Here are some of the videos containing the build and first run. Hope this helps mate, Terry.# Work Starts On The New RDF. Building the RDF case. kzfaq.info/get/bejne/a7SJfLCLqs6YhY0.html Good Pond Clean & More On The RDF.

Me and my good lady said the same thing tonight. I told her he had uploaded another video and her first words were "The guy that used to have the jolly music" hehe. Looking forward to how this drum filter performs. Thanks for the video.

Thanks guy's, I will change it as soon as I have time. Promise :) Thanks, Terry.

Hi Lee, I got the mesh on ebay. Terry.

Hi Owen, It's a 2 pack pond paint. Thanks, Terry.

Hi Lee, I'm just building the moving bed so I can take out the Pro and fit the rdf in the shed. Thing is I've got to set the Pro up outside so I can re-pipe for rdf. Plus I leave the paint a week to dry really hard. Terry.

There is always work to be done with pond keeping I am off this week rebuilding mine due to a leak just couldn't find it to repair it. :( . Anyhow might have to pop over and see you again when you all sorted to see it in action as thinking of buying one.

Like I said in the video, this rdf has got to be good to keep up with the Pro system. I do love the way it works and the fact that the dirt doesn't sit in the filter for a week. So I've got to give it a go. I've just been looking at UV's. for the rdf WoW! £300.00+ for a UV is crazy.

Please try in TomTop.com, you will 13 w uv for 10 dollars. You can buy 2 or 3 of them and save money. I have personally ordered that for my future build. I got it now, its too bad for the cost.

unable to edit, i mean, its not too bad. its good. Pardon me, english is not my first language.

Hi Richard, I moved the Pro out of the shed and put it on the patio and set it up to keep the pond filtered while I re-plumbed the shed for the RDF. Got the RDF installed, switched the Pro off and went to start the RDF. Switched on and all was running well. went to look at the pond and you couldn't see the fish, the pond was full of dirt. It was then I remembered I had no one way valve on the Pro and all the dirt it had caught went back into the pond lol. Never see my pond so bad lol. so the RDF had a right job on form the word go. It's been on the pond 2 days now and has it just about got it cleared up. Apart from that mate which was totally my fault, its going really well and I'm really pleased with it. Thanks Terry.

Hi Ken, if it performs as well as I think it will, it will be a great little filter. I will be doing plans of the build and have them on my website once I know all is well with it. thanks, Terry.

HI Angela, Not usually. You could take some pictures and send them to me @ pondfilters@gmail.com I'll help if I can. Terry.

Hi and thank you. Very much appreaciated. You can get them from farming suppiers. I'm still testing the rdf and may change things, so I don't wan't to tell you wrong as I may still change them, and as they cost £10.00 each there not cheap. Also the company I used are UK suppliers only and do not ship abroad. Terry.

Hi Wa, Hello from the UK. You will find the build plans for this RDF on my website diypondfilters.com I have built a new version of an RDF and it's built using PVC. you will find them there as well. My email is pondfilters@gmail.com Terry

Thanks Spencer, very much appreciated. Terry.

whens next update mate.

Will be soon mate. Been a bit busy and want to give it a good run to make sure everything is good and working. thanks, Terry.

Hi Matthew, I can't release anything at the moment as it's not been run on a regular basis and things might get changed if they don't work as expected. I am working on the plans at this very moment. You can get the mesh on eBay if that helps. Terry.

Thank you. Terry.

I did look into it but the cots of just the case would have been £400.00 plus. Terry.

if you contact E I P ENG IND PLASITICS they are in hampshire they are suppliers of poly prop you need max 9mm biege sheet then look on ebay for a plastic hot air welding gun with tacking jet and speed jet E I P will also supply you with welding rod you can make your own tanks and barrels you are clever enough to do it no more than 150 sterling for the plastic to do the lot one of my companies in the UK was H T S ELECTROPLASTIC

Hi Humphrey, I will certainly have a look into it mate. Sounds good. Thanks for the info, very much appreciated, Terry.

Hi Humphrey, I did go to IEP, Ltd for a quote and it came back at £241.00. to make the filter box. I do have a heat gun but most people won't, so if you add that to the cost it soon mounts up mate. I'd also have to add some structure to the outside as it's only 9mm and would need help to stop it bowing. The case I build was less than £100.00. Thanks for the idea though mate, it's good to know. Terry

hi terry that was that a price for a whole tank or just the plastic can you tell the size of the box and i will let you know what you should pay regarding the heat gun i have seen a proper welding kit on ebay for sixty pounds once bought you can make breading tanks etc a eight by four by 9mm pp should cost no more than 80 pounds you could come down to 6mm regards
