Well it's nearly time to set up the new tank and i was wondering what sized pump i should use as a return. The tank is a 36 Gal with an overflow box, 1" bulkhead and an external durso. Return line would be at approximately 48" of head. I have had problems with getting the water to drain quickly through this type of setup in a previous tank so i was hoping to get some advice from someone with a similar setup.
thanks
