I bought a 125g (long) none drilled tank. I plan on drilling it myself(handy guy)
im going to have a 40g sump.......intake(with skimmer>>return>>refugium.... wll be my lay out.

-ll be drilling two holes in both upper corners of my tank for draining.
-myreturn will be up and over with pvc
- going to be using power heads for movement in the tank(3 mj w/1600gph mod)

my questions are:
-how much flow do i need ciculating in my display tank
-how do i calculate sump flow
-how do i know what size pump i need in the return section of my sump.
-what size plumbing pipe do i need for the drains and the return up and over pipe.

I can't help you lol I'm a total doofus noob. I'm still trying to wrap my mind around drilling holes into something that's supposed to hold water!
