If you pull the coral out of the water and look at it under normal lighting does it look any different?
this is the problem with using the lights that we do in our tanks. ( I am referring to real high K bulbs like radiums ) they make the color look wild when they are on but if you look at the coral under normal sunlight they are brown (talking acro's )
back to the black light it does react more intensely with the phosphorescent pigments in the coral and cause them to Fluoresce more intensely but I don't think it has the intensity needed to physically change the color of the coral.
