| Re: The perfect flow for a mixed reef tank I think as the surge is leaving the holding tank, the pump is big enough to start pumping the water back into the surge tank to prevent the overflows from overflowing. Also when the surge tanks are full, there should still be enough water in the DT to allow the overflows to work properly. I think its got to do with having the timiing just right??? I'm not experienced in this type of flow at all. Might be one of those reasons why I don't even consider this style for flow in my tanks. |
