For tropical fish, I always advise sand, not gravel but in a goldfish tank, undergravels are useful as they can quickly trap the amount of muck the fish produce. Poorly maintained UGF will produce lots of ammonia and an external will always be better but the addition of a moving bed can process the ammonia very quickly. Later videos of the moving bed filters have much better designs (less ugly) and I am currently doing a redesigned one for a company to show in Nuremburg in May.

@pondguru Sorry im not trying to bash your video or filter, just trying to figure out why you would use that compared to many other filters that do the same and don't take up room in your tank and are less sore on the eye. And ofcause the UGJ thing i mentioned first, as I see that as the main reason to many ppl have ammonium spikes in the first place. I might misunderstood your video, I thourt u said it was a good option with UGF. Best option for UGF is not to use it IMO.
Cool just bought some of your media and I'm going to ad this easy cheap filter to my already working diy sump filter. Love diy stuff!! Thanks

It can take many months to develop the dark colour so I wouldn't wory about that. The fact that it has some noticeable colour is very good in a month.

I have one of these filters in my 75 gallon quarantine tank that I use for growing on koi , I cannot recommend these enough , my nitrite levels are now a very consistent zero even with fair high fish stocking levels ,
Thankyou .
