65 gallon powerheads

[cklop09]

I'm having a hard time getting the flow figured out in my 65 gallon tank.
Dimensions are 36x18x24
Im trying to have a mixed reef, soft/lps and maybe a few easy SPS.
I believe I need to be around 35 gph for this to be feasible.
If this is true, 65 x 35 = 2275
HOB skimmer = 240
Canister Filter = 200
Powerhead A = 800
Powerhead B = 800
That leaves me being 235gph short & those 800s seem awfully strong for the 3ft wide tank I don't want to go any larger

You could buy powerheads that are adjustable, so if it turns out to be too high you can dial it back.
