Corals loosing Color???

[rgentry]

Over the last month my frogspawn, torch and open brain have lost much of their color. The are somewhat translucent looking. My water parameters have been fairly consistant. My lighting, 440 VHOs, is due to be replaces, almost a year old. Could this be the problem? Any suggestions appreciated.

I would say that it probably is the lighting.

Sounds like bleaching - of course, without knowing anything at all about the tank, its hard to say whi this might be happening.

Eric,

I've have a 75g reef tank with a 15g sump and a 15g fuge. All my water parameters have stayed consistant and within normal range. What would be some reasons that would cause bleaching? I'm going to start to replace by VHOs today. If the problem is lighting, will the frogs, torch and brain regain their color?

Thanks
