Hi everyone I am new to this site and pretty new to saltwater. I got a 240 gallon that I’ll have on the first floor and plan to set up my sump in the basement. The tank came with 2 iwaki md 30rxt pumps. I was wondering if these were powerful enough to be return pumps for a basement sump? The vertical height to pump would probably 12-15 feet. Their are 2 intakes and outputs on the tank. Thank you in advance!
