75 Gallon Powerheads

I have a standard 75 gallon tank. On the back right i have 2 Hydor Koralia Nano Stream Powerheads 240 GPH Each. On the left side i have 1 Hydor Koralia Nano Stream Powerhead 565 GPH . That should give me 1045 gallons per hour not counting the return pump. My question is this. My corals especially my kenya tree is not happy and some of the other corals dont seem to be growing. My water is great as far as parameters go. I am running black box lights. Can the problem be i just dont have enough flow or maybe because these pumps are Nano Streams not a wide enough flow. Any suggestions would help. Possible changing out the 2 heads for a bigger one and leave the 565 on the opposite side? Thanks.
