Hello BRS. Im just curious if/whats the significance to painting the backof my tank (if any), and what color would be most advised? I have a regular 10 gallon with x2 24W T5HO. I plan on restocking with corals soon (had a real bad crash where EVERYTHING failed) and im curious if it would be smart to spray on a brighter color paint to help reflect light. Maybe something like an aqua blue or a similar color?
