whats the best placement for powerheads in a 55 gal FOWLR tank. I have two Rio 800, is that enough to circulate the water? I also bought a spinner with two duckbill inserts for one of my powerheads. where should i place this?
be careful with Rios, they have a habit of burning up and dumping oil into the tank, killing fish, rock, inverts...you name it.
keep them clean and that should make them more reliable. if one burns up, replace with a Maxi-jet.
