I am in the process of setting up a 72 gallon reef tank but I don't know which water pumps to use. I don't have any pumps for the currents inside the tank yet. And I need a stronger pump to pump the water back into the tank from the wet/dry filter.
The sump is a little less than 4 feet below the tank or about 4 feet and I think it is like 1/2" pond tubing for the return. Right now I have a ViaAqua 2600 pump for the return but the current just isn't strong enough with this pump. Do you guys have any recommendations for pumps just for water flow inside the tank?
