Flow for a 6-8' sps peninsula

[Proteus]

My tank is a shallow peninsula has rw8's on each end plus a mocean 2000. Flow is pretty good but as it grows in I may need to put a few more on the ends. Only issue I have is tank only has 11.5" of water so bigger powerhead were not a option

On my last tank I used directional bulkheads and was able to get really good laminar flow.
