Fla. rics bleaching??

[koletangz]

Is there anything that would cause my florida rics to bleach besides lighting? The are under pc lighting 130w over a 29g, they have done fine for about a year, but now two of the colonies have become bleached. Thanks for any help you can give me.

Did you changed the lighting recently? My two year old orange ricordeas melted when I switched to 2x250 watt metal halides.

no the lights were not changed

I would check your ca, alk, and salinity levels. Those all could cause bleaching.
