Hey everyone I’m having troubles deciding on a return pump for my current situation. I recently purchased an eshopps Rs-100 sump got it for a great price. Now the issue I am having is the 4” wide return pump section. My tank is a 48” long 90 gallon tank. I can’t for the life of me find a 4” wide return pump with a high gph rate. I am planning to hard plumb my reactors and chiller all together with my return pump,plus the head loss I will be losing getting to my main display. Does anyone know of a 4” wide pump that kicks butt??
