The only reason I tried multiple laminar flows, disrupted by surges, which they call "turbulence" is because my tank was over heating, I suspended lights (T8) that was not the problem. So I found out the power heads when run constantly increase the heat in your tank by several degrees. In my case, it went over 86. So you are looking at reducing the pumps, or buying a chiller. What I found to be true is on a wave maker between 20 second to three minute intervals its goes from 78 to 82; I turn the A/C off at night because I don't like to sleep with it on. If room is 74 to 76 degree’s I’m good.
So basically flow “sucks” in all tanks, it took months to design surges and turbulence:
½ circle ten gallon mini reef:

Wave maker outlets 1 and 2 alternate
[*]
2[sup]nd[/sup] cycle outlet 3 goes on for twice as long

Two spray bars on ½ PVC with a 402 power head on each end (480 GPH on PVC) 1/4 wholes every inch (spray bars are in outlets one and three) less frequent bottom flow because nothing liked laminar flow constant on bottom.
480 GPH bottom back, still, 480 GPH bottom back, 480 GPH middle up over lapping 480 GPH bottom back creating 960 GPH (two directions: bottom flow and surface agitation, repeat)
Then I re-read article on flow so 480, still, 960GPH on two spray bars are disrupted by left and right surface on outlets 1 and 2 same wave maker (maxi jet small power heads 106 GPH)

The mushroom coral live rock is position between bottom and top flow, and left and right, took months to not blow the mushrooms off the life rock, not scare the fish, let the fish sleep (plugged wave maker into light timer), still get heavy flow to grow coralline fast (hours), mushrooms open up, and tank is very, very clean.
