I just purchased a Seio M620 Pwerhead to replace my Aquaclear 350. I needed more flow in one section of my tank. I am notiicing very lilttle diffrence from this powerhead and my aquaclear. The aquaclear is rated at 350gph and the Seio is rated at: 620gph. The seio is fully open?
Did I get a DUD, and if so, how good is MarineDepot w/ returns?
