This one has me confused. I've been slowly dimming my radions bi-weekly. They are currently peaking at 75%. This has been my attempt to get the color back into my SPS
, though not all of them are doing it. Only the pink Stylophora and birds nests are white. I'm assuming that my blue bottlebrush's lack of color is also tied into this issue. Ignore the few pieces of birdnest w/ algae on them, they are sacrificial as I would clean it off and the problem would get larger. Radions are 20 inches above the tank and running a bell curve cycle, only at 75% for an hour max.
