Sorry, the maxi jet wasnt blowing on it. I have that as the return pump from the rear chambers. I had a rio 180 blowing on it that is rated at 120 GPH only. Thats a real bummer. I hope the rest of it will be ok. The problem is that with that extra powerhead in the tank there is nowhere to aim it that doesnt cause my sand a soft corals to get tossed around. Plus it looks junky in there. Do I need more flow than the single maxi jet to keep the SPS happy?
