It depends what kind of corals your gonna want to keep. For some corals a PH pointing right at them is too much flow. I have 3 PHs in my 29 gallon. One maxijet 900 pointing behing my LR to keep it clean back there. I have 2 maxijet 1200s, one in each corner pointing towards the middle front. The flows colide there and then go over my LR etc.
