Under gravel filters
Most definitly we use powerheads on the 55 and the 29. Bubblers on the 10’s and yes we deeply siphon moving the gravel(side to side) to get better suction from under. I was disciminating some info I didn’t think made sense. We also have filters on the back of the tanks. With the powerheads we get very little from siphoning. Bubblers just don’t have the pull, Get quite a bit from the 10’s. Biggest problem is over feeding ( our daughters ) They get distracted by the fish and forget to pay attention to the amount of food they are feeding.
