MP40 placement for Bare bottom Reefer 350

[aaron186]

I’m restarting my Reefer 350. I plan on going bare bottom with SPS dominant and running a roller mat in the sump. I currently own two MP40s. I want my power heads on the back wall. I see a lot of people placing power heads near the bottom to of bare bottom tanks to keep the detritus suspended. If I put my MP40s towards the bottom on the back does this mean I should add two more MP40s towards the top? I would run them on low. It seems overkill though. Anyone else doing something like this?

id just run the 2 low till you get it full of sticks then adjust flow, alot will depend on your rockwork
