I have one on my 48 gallon. It's paninsula style without being positioned in a paninsula. I actually sold my mp10s for the maxpect. Flow is excellent. It moves water very well. Some people have had bad experiences with small snails getting caught in the propellers, but it hasn't happened to me. ..yet. It is a bit loud at 75% power. Easy to program. I'm happy with it. I might get another one later on but my corals seem fine with just one. I just leave it on long pulse, which is about 6 seconds on, then briefly off.
