Thanks for the input HMA. But if I have low flowgoing into the refugium and low flow out. And used powerheads just to add turbulence, wouldnt that be ok. I know that you want to have long contact time with the algea, but the flow through the tank would be low. Also the frags and eggcrate would cut down the light that reaches the Chaeto. I just thinking right now.~Michael
