I recently picked up two MP40s that I am using on either side along with 2 WAVs that are mounted in the back towards the bottom. I really want to move all four pumps to the back wall blowing over the top of the rock, hitting the glass, and forming a gyre. Currently some of the SPS is taking some damage being so close to the MP40s on the sides along with the fish getting blown around quite a bit. Does this seem feasible or are these MP40s better off on opposite sides colliding in the middle? Will this type of gyre flow provide enough of a chaotic flow that SPS like? This is the tank when it was first set up about 10 months ago to show the rockwork. I am used to just keeping the pumps on the sides.....then I watched one of the BRS MP40 videos showing how nice they look hidden on the back wall lol.
