Ok so I am doing a 75 gallon reef tank and have my tank with a overflow in the middle that's about 12inches across and maybe 6 deep. It has 2 predrilled bulkheads for return and outlet to and from the sump. Now I'm generally new to sumps and wanna do this right, I purchased a 29 gallon sump with 3 chambers along with a corallife 65 skimmer. My question is what kind and how powerful of a sump pump do I need to get? Also what kind of plumbing parts should I use? I want to do a refugium and plan on using as much lr as I can afford. Any suggestions on a pump that won't brake the bank and will last? Thanks y'all!
