One more thing I forgot to mention. I was messing with my Wavebox about a week ago, and I've now been able to get a solid 3/4" wave from it. I finally got the correct frequency of .70 in my tank. It appears as if the wave box control is designed for standard tank sizes (48", 60", 72", etc...). A 48" tank needs a frequency of .65 seconds. That speed can be dialed in pretty easily on the controller. When trying to adjust the frequency any slower, it wants to jump to .75 seconds. I would go back and forth between .75 and .65 and could not get it to stop at .70. Every now and then I could get a .67 or a .73 and I would get a slightly higher wave.
Timing the frequency is not that easy. I finally decided to just count how many complete waves occur over a minute's time.
40 complete waves = 80 cycles. 60/80 = 0.75.
45 complete waves = 90 cycles. 60/90 = 0.67.
42.5 complete waves = 85 cycles. 60/85 = 0.70.
I finally was just determined to get it to stop at 0.70. After almost an hour of messing with it, I finally got it, and whoala! I now have a solid 3/4" wave. This controller is very very finicky. It almost always stops at either .65 or .75. If you have a custom sized tank, have patience in dialing it in.
According to Roger's wavebox flow calculations, my wavebox is now producing about 5200 GPH of flow.
Add that to the 4500 GPH I get from my two 6080 streams + the 800 from my Iwaki 30RLT return pump, and I now have 10,500 GPH of flow. 10500 / 150 = 70X tank volume.
Right now this BB system is running pretty much flawlessly. I have no undesirable algae growth. My fish are all super healthy, and my water parameters are staying in check. My corals are all growing nicely, and life is good. The only problem is that my rock continues to shed detritus which likes to stay suspended in my water column. I'm hoping this will subside soon. I notice it sheds a little less now, but I'm not sure if that is because of the Prodibio or because the tank is maturing.
