Great thread about flow. I'm on page 3. Planning to read the whole thing.
I think I might use dual overflows and put the return section in the middle. I am going to use a Tee and a valve on the main overflow line to control flow out to my refugium. Excess water in that overflow line can go to the skimmer compartment.
I may run some tubing from the skimmer outlet over to the refugium and set it up on a spraybar. Or just dump it in there. That would help oxygenate the water in the refugium. Might be overkill. Thoughts?
