Been far to busy to spend much time on this project lately, DAMMIT.
But lotsa shopping online

things are coming together for when I actually get some water flowing.
A few goodies:
From Concept Aquariums:
From BWA:
Set sump in place so I can get plumbing on the go.
Making 2 return lines , one with manifold for reactor lines and one direct return.
Direct Line
Manifold
I am still not sure about the overflow, but will fill with water and run it for a bit and see if the Durso works for me. Might have to drill a few more holes.

Looks like the pumps I have are big enough, but I think I am going to pick up a DC pump and try it out.
