Yes, I think the OP should reduce his flow a lot.
I've unplugged one of the powerheads and I'll be going back to check on it today. So I'm at a bout 540gph with the current set-up. I suppose that's closer to the goal of 30-50 times turnover. I can also restrict the flow of the filter to 0 if I want, maybe I'll plug in the other powerhead and slow down the HOB
. I understand this may be a fine tuning issue. And yes the Damsels are plenty fast to catch the food in the tank, but... point taken.
