I was thinking of doing a white bare bottom but I don't see much about it everyone uses black does anyone use White bare bottom please your comments will be appreciated
White will reflect up a lot of light thus taking away from corals.... That's also a reason why a lot of people are not using a generally light background
I had white SB on a previous 180 and for the 405 decided to go in black. While I agree that over time Coraline will encrust much of it, the black helps the coral color to pop while I always felt that the white made my tank look more washed out.
