Flow Pump Help

[snackattack1x]

I've had my reef aquarium going for about a year now and flow has always been my biggest concern.
My tank currently has two 750-850 GPH and one 550-600 GPH Hydor Koralia Evolution wave pumps, but I'm thinking I could get better results with something else.
I have a leather, hammer, and alveopora on the shelf. Zoas/Palys on the rock tree and right side of the shelf. Green star in the back right. Birdsnest on top of the rock tree.

Do any of you have recommendations or better options for coral health?

What size is your tank? It looks like a big tank, and those seem like small powerheads to me. I use 2 x 535 gph powerhead in my 15 gallon, just to give you an idea. My 40 breeder has 2 gyres, plus the return flow, plus I added another small powerhead behind the rocks.
With that said, your tank is very open with minimal rockwork and not much coral at this time. You can always add more flow as your situation changes.

I recommend that tanks should have 20x turnover minimum for optimum tank health.... my tanks run at about 40x turnover. If you have a 100 gallon tank for example, then 100 x 20 = 2000 gph to achieve 20x turnover. So if you have a 100 gallon tank and want 40x turnover, then 100 x 40 = 4000 gph.

It is a 75 gallon tank. I also think the flow is too low, but I was too concerned about blasting the corals or fish.
Do you think my tank setup would work better with something like a gyre?
