What size tank again? How much GPH is the powerhead? I'm a bad person to ask that question to... I'm a flow nazi. I like pointing powerheads at one another for a chaotic flow and really max out in the GPH game. One MP40 should be enough for a 55 gallon tank...but I have two AND a koralia that I don't recall the GPH on.
