Hey Bro, check out my new fx5 config, I took ur suggestions of more ph, but I'm a Baller on a budget, more flow with out the dual outputs, fish already swimming in it. Seems like 1000gph and fx5 should be enough current:
Nice idea. Have you considered swapping the ribbed hoses for clear vinyl? Then you could just use pvc as a return. I have my return go to a pvc spray bar, but it could easily be an elbow dump. Youd probably get some serious flow that way.
