I tried almost every thing, the guppies just kept breeding like crazy :) My problem was that I never kept a setup for very long before I changed it to something else !
I really miss the early days , it's good to see you still here. Maybe a small tank sometime in the future ,something small enough that the carpet can soak up before it goes downstairs. I had 4 Fluval fx5's on my last 2 tanks and when I started having leak issues on one it set in the fear factor...
