But with a burrowing animal RUGF's are kind of sketchy IMO. This ain't first hand experience, just an intuition.
I just ordered a #3 Koralia powerhead from Hydor, designed for water movement...I'll post the effectiveness when I find out how well it works for that very thing...fenton06;2715805; said:ok, so if the rugf filter is a bad idea, is there any way to keep stuff from settling on the sand? Would a powerhead near the surface of the substrate creating currents on teh bottom work?

stealthy is cool, but you can't have everything...."just the fish" is going to include either daily maintenance or visible poop...fenton06;2716015; said:I'd like to keep it pretty stealthy if possible
i don't want to be able to see the filtration... just the fish!
