making close loop system

Closed loop is drain and return at same head.

What you have see referred to as a manifold (see picture here).

Yup, a manifold indeed! I'm hoping to build one for my next tank.

No metal, that's right

OK then, I need to change the title LOL

A very nice looking manifold at that. My concern with it is that you might not get the flow you want with a Mag 12 at that head pressure. Did you say that you were thinking of a mag 18? I think it would work better.

Ahh, ok. Was thinking an 18 would have been to much?

It's somewhat surprising what some elbows can do, to drop your flow. Check the calculator out to get an idea with your layout and different pumps.

I was just thinking, would the Mag 18 be too much flow for a 15G sump tank? Was thinking rubble and sand, skimmer at a later date in the sump. 15g is the largest I can fit, and be able to remove it
