120 gallon powerhead question.
I currently have 2 mp40 on each end of tank. I am running a bare bottom tank. Should I put 2 mp10 on back wall down low to help clean bottom or 2 more mp40?

I have a 120 BB with (4) MP40's. (2) on one end mid height, (2) on the back toward the top.
The end pumps run @ 100% 8am-8pm, back 40% in NTM, then 8pm-8am end 80% back 30% in Reef Crest. The bottom stays clean. I would go with 2 more 40's. You can turn them way down if need be for less flow, but if you need more the 10's might not be enough.

My 120 was not barebottom, but I ran 3 MP40s. One on each end, on on the back. I probably ran them at around 75%, but it's been a while and I don't really remember.
