so i have a 75 gallon with a lone 11" red devil, a rena xp3, and a powerhead that i have an air hose connected to. i want to remove the power head and try a circulation pump instead. give him a bit more current for a little while. but i cannot have an airstone in the tank. he ends up dragging it across the tank or pull the air line out.
my question is, am i getting a enough o2 in the water with just the filter?
