Rigging my factory blackman tank. Water comes in straight up from the bottom. Custom made a diverter to flow water in a counterclockwise direction. Now ready for the pump. Been looking at the rule pumps is the 1600gph to much pump? What size is everyone using. Looking for a low amp draw pump. Think stock tank is 60gal? Was going to go with a shureflow 1100 but after reading posts don't think it's a real good pump.
