Looking for some help getting my flow the way I want it. I've got a Red Sea Reefer 250 and 2 EcoTech MP40s and 2 MP10s. I have the 40s on either side of the tank and the 10s in the back. During their break-in period as I ramped up the speed I noticed my sand (CaribSea special grade) being blown around. Particularly it's disappearing from the center of the tank and piling up at the sides. On the left it's pretty much right below the powerhead. On the right it's further back in the tank than the powerhead. I attempted to crank all the heads down to 5%, which did stop the sand from blowing around; but I noticed I had virtually no surface agitation.
The MP40s are both about 8" below the water's surface, which puts them almost 10" above the sand bed. The left one is about 7" from the front glass, and the right is about 4" from the front glass.
The left MP10s is about 10" below the water line, and 8" above the sand bed. The right is about 14" below the water line, and 3" above the sand bed.
The powerheads are placed in those locations because of the aquascape (to ensure they're not directly blasting the rocks). The pictures are of when the tank was first setup, so it doesn't show the sand disturbance. The red circles indicate where the MP10s are on the back glass.
My goal is to have no dead spots (hence why I put the MP10s on the back), good surface agitation, and no sand bed disturbance.
Suggestions?
EDIT - Note - I'm likely going to remove the MP10s because they have trouble sticking anyway. Glass is too thick.
