I do have the heater and everything in the sump. The only reason that I have the Power head set so high right now is the anemone has not settled yet. When It does I will move the power head back down. I think the wire that you though was going to a heater was to the temp prob. Still not too sure where to put that. I was not sure if I would want that in the sump or not.
Sorry just looked at the pictures again. You might have been looking at the right side of the tank. I have not had the $ to get a second power head yet. I have my old Rena 3X running over there. mostly for extra flow.
thanks for the advice
