Is this too much flow or no?

Hey guys I just found another power-head in my storage that I completely forgot about.

So far I have:

Hydor Evo 1050gph (One side of tank)
Hydor Evo 1400gph (Other side of tank)
Return pump from sump at about 900gph (Quiet One 4000)

and I added another powerhead at 600ghp in middle of tank with a slight curve to the right.

Total of 3950gph turn over rate in a 90 gallon tank

Is this ok or ? Are positions of powerhead ok ?

 

43x turnover is fine, just make sure to keep softies like mushrooms and such out of direct flow. The positions of the power heads is fine also

 

Sounds good, I have the same flow in my 75 so you could probably boost it if you wanted.

 

Ok thanks guys.
