Red Sea Reefer 250 - Sump options

[WhatCouldGoWrong71]

What Size PVC is needed to plumb this tank? I have a friend that has a e260 and just got a sump for free. But He doesn't know what Size PVC to get to plumb it.

They are metric I think 25M and 32M. There are ways to convert them, I have a 250 that I converted to 1 and 3/4 inch you can google it. You can convert through unions, adapters and couplers. Depends on what you want to accomplish.
