I'd like to just commend you on concealing your filter nicely. So many DIY filters people have them sitting right next to their pond. Sure they work great but they're ugly to look at. Well done.

Hi Gareth Thank's for sharing

You are completely in love with how you can turn the air on and off on both sides. Great looking setup though.

Hi Gareth Thanks for the quick reply! I have four 20 Gallon tanks, first tank is a settling tank as i was unable to install a vortex. The next two tanks will be K1 and the last tank will mostly be Alfagrog & Japmat. The oxygen in your tanks is perfect, just what bacteria needs :) Thanks again!

Hi Gareth how are you don't be shy about talking and describing things :) .

great job. i think youll find that your brushes will clog rather fast. you can turn 1 of your moving into static k1

Nice diy job mate. Well done

@poisonXvenom This is a conversion of an old 3 bay filter. The far left bay still has brushes in, the middle bay now has static K1 with the air feed for cleaning, and the far right bay now has a moving bed of K1. Hope that helps. No this is not an ERIC filter, its a bit like a Nexus filter..

@plodplayer I went to the original maker of the filter box, which I bought back in 1996, called CD Aquatics in the Midlands. They dont make filter boxes any more but he had a few bits left which I bought off him. Not sure if he has any left now though.

subscribed. nice filter. i have a 1000 gallon pond on my channel. I need to build a custom pond filter like yours soon. I dont like cleaning my oase 500o everyweek

Very interesting filtration!

Nice set up 👍

The air ayatem is quite good actually

Looks good I mite give it a go my self

could I ask ..how to make those air rings at the bottom.. or where you purchased them..its exactly what I need for my filter box..great job

Hello, nice video clip - did you use two chambers for k1 or only the last? greetings Roland

@lespauldfx Hi I used a Hailea ACO 9720 30L/m Pump as it was cheap. But it works fine. Hope this helps.

Hi Gareth SUPERB Filter conversion!! May i please ask how many litres of K1 was used in the moving section??

I'm a just a hobbyist...but I don't know what I am looking at...a description of what is going would be extremely helpful...

Hi , I can not remember the exact figures, but I measured the volume of the bay in ltrs then fill exactly half with K1. Hope that helps.

Hi - Thanks for the video - could you describe how each compartment is working? Manu thanks

Hello, I like the video, I have question, Where did you get that sump from?

hi Gareth do you still visit this site? if so can you explain how you constructed the air rings in your filter boxes, i constructed as you have in the photos and I have a 240 LTR per minuet pump only a few bubbles around the t piece came out. what's going wrong please

Hi Gareth where did you purchase the air rings I'm making my own Koi filter many thanks robert

Tip. Buy a Nexus

Nice. Any updates?

How about now sir?

Hello, may I know the ratio of the K1 media? How many K1 media in 1 container? Around 60%?

so is the left side where the static K1 is going? and is this an eric filter?

What size tank are you using or are they 3 separate tanks !!

Where can I get the tank filter that you have?

Hi I bought this pump and am having trouble with it. On te box it said you can hook it up to a 110v so I bought the international plug and put it on the 110 and it does nothing at all pump turns on but has very very little air at Alll. Do.u have urs hooked up to a 220 and do u think I'm not getting enough power?

can you tell me what type of air pump you have and how many ltrs

What is that filter made of, (plastic) ?

Need your help ASAP do u have this pump hooked up to 220 or 110???

sir how many liters of k1 did you use for this?

I know this is an old video, but K1 is only useful in the fluidized/moving bed filtration chamber. The static chamber would be better filled with pumice or ceramic based media, which has much more surface area.

better water ???

Let's get it out there. I'm so very jealous of my neighbor at the moment. He's actually been alone always and forever. Then again he's mind-fucked a swimwear model to tell him she has fallen deeply in love with him in less than a thirty day period. Just how is that thinkable? He smiled and told me he tried the Cupid Love System (Google it!) I wish someone amazing told me they loved me... I cannot remember ever seeing him so cheerful. Kind of makes me feel bad.

great job. i think youll find that your brushes will clog rather fast. you can turn 1 of your moving into static k1
