I'm already finding that food goes right through my five 2" Cichla. They're going in my 125 soon and want to make it as easy to clean as possible. If I stick my 325 gph powerhead on the right wall, it should push debris down to the left, correct? I'm not saying I won't have to gravel vac the right side, but most of the fish waste should accumulate on one side, right? Anybody have any experience with this technique?
