Small tank? Seriously? The freaking thing is 240gal and I have 2 fx5's running, full of media. And to everyone else, about the waste: I'm getting in the habit of cleaning the gravel once a week, resulting in about a 30%ish+ water removal. I recently found I have high nitrates in my refill water(40ppm), so I don't want to do too much change at once. My only problem is nitrates, but I was doing water changes so much, I think I was making my own problem. Got my 2nd fluval and filled it w/ biomedia. So far, my hunch was right and my tank nitrates have gone down w/o my almost daily water changes. So I'm working on perfect water perameters. Everything else is good though, ph, ammnoia, and all that
