I will be using a 29g tank for the refugium on a 90g reef.
The refugium is 30 long x 12 wide x 18 tall. I'm not sure how to lay it all out.
LOTS of questions:
Do you want the skimmer and refugium on opposite ends with a center return? If using this method, can you simply run 2 overflows and drain each into opposite ends of the tank? Do you WANT to do that? Do you want to drain unskimmed water into your refugium?
Do you want the refugium first and then the skimmer and then the return section?
Do you want the skimmer in the first compartment and then the refugium with the return section on the end?
So many options.
