mp40w on a 90gallon
I have a 90gallon sps dominated tank. Would a single mp40w be enough water flow for the tank?

If you have a sump, put a sea swirl on your return line to give the tank random flow.
You'll love it! ...oh yeah, IMO will a little extra return flow, it should be fine if your not overstocked or don't have like.. 200 lbs of LR.

I have a 90 with 2 mp40's. I ran it with one for a while but wasn't getting the flow that I wanted. It can work but to get enough flow on the opposite side, you really have to crank it. But that means the near side gets blasted.

2 would be more better, I have two on my 75g and find it to be perfect.
