I have a 55 gal and am looking to add some corals (right now I have FOWLR) is two maxi jet 1200's about right? I figure it'll put me at almost 600gph which is just over 10 gal of water movement per hr. per gallon. Is that correct?
I run 2 MJ 1200's in my 40gallon reef. no sump return. it's just about perfect
aim them at each other, angled slightly up towards the surface. this'll give you good surface agitation for gas exchange, and the colliding streams will create a pretty good, semi-shifting current in the tank.
