making close loop system

Ya, The overflow drains to the sump, where I will have a mag 1200 pumping into the loop, via the PVC in the back. Sorry if thats not a closed loop???? I was under the impression that the Loop itself, is what they call closed loop, because you allways have a drain and return from the sump???

And on hose clamps, Plastic is the only thing for inside the tank???

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.
