@CuzzA my maxijet pumps max out at about 295gph aonI dont think that will be strong enough given the distance i have to travel. I have a mag 9.5 which is about 950 gph so that woukd work if i use a valve to reduce the dlow but its too big to deop in the tank. This is where Im stuck now unless im misunderstanding something but it seems any powerhead w enough flow woukd be too big to drop in the tank. I want to get this in the tank tomrrow though so i can keep this from getti getting worse.
