They have to be able to drain more water back to the sump then the return pump is returning to the tank. So with that being said. a 1 inch pipe will drain about a 100gph and a 1 1/2 about 1600. so you can do the math on that one. On the PH's you kinda lost me on that one, can you explain what u want to do with them.
