I just bought a 72g bowfront from a guy. I was setting it up today and found that the sump powerhead is dead. What powerhead should I get? The rise is from the floor to the top of the tank - 4.5ish ft.
I'd get a pump instead of a powerhead for a return. With the head loss you'll be better off. I'd recommend an Eheim because I love mine. There are other ones though, some more and some less.
