Looking to hardpipe my sump in Red Sea Reefer 200 xl G2. Can anybody tell me what size pipe is coming off of the bulk heads? Going to add a manifold to the return in hopes of installing a UV light. Everything I have is 3/4. Trying to figure out if that will work coming off the return bulkhead or not. This is my first sump tank so I'm new to this part.
TIA
