i just bought a maxijet 900 powerhead. i have a 75gal tank. are their any smaller power heads out there? also with that powerhead i have about 500 to 600gph input from my sump. is this enough circulation? i was planning on getting one more powerhead.
You should get 2 mini-jet 404's, or two 606's. the 404 is rated 13-108 gph. And the 606 is rated 79-153 gph. Great for getting behind the rocks, mabey place one on each side. Here's what they look like.
