Okay, what's your source water? RO/DI?
I would reduce your light schedule to 6 hours max. Reverse running your refugium light to that of the display tank. Display lights on, refugium light off. Display light off, refugium light on.
You could be overlighting the chaetomorpa, causing it to pale. Corals, macro algaes need no more than 6-8 hours of light. Dark periods allow tissue and cells to repair themselves.
