right now i have 4 pumps in my 75 gallon reef but only 3 are on at a time. 1 hydor 1050 2 hydor 750 and another no name 750 i have the hydor 1050 on one side, then a 750 on the opposite and then the other 2 on the back walls. right now i have the 1050 and the 750 pump on the back wall alternating every 5 mins with my RKL do you think this is to much flow? its mainly sps and i see the flow really crashing on all my sps nicely moving polyps all differant directions i just didnt know if i over did it. btw no sand is moved with all the flow in the tank.
