Rock turning white
 

Where my rock was a nice purple it has turned bright white at the highest point of the rock as if it was splashed with bleach.

Any Ideas??

New tank ? ... new lights ? ... new rock ?

yes....yes....no

What do you have for lighting..??

Probably just bleached from the new lights ... what type of lights/bulbs are they ?

coralife 2 X 65w 10k 24"

has your water level dropped in the tank?

ummm....yeah everyday I add about a gallon every 3 days...it has never come close to dropping to the level of the rocks... if thats where your going

Any hermit crabs? Mine always seem to feast on coraline algae. :sad:

IMO its the new lights. I just upgraded my lighting and noticed some coraline loss on some rocks, aswell as some mild bleaching of corals. It should grow back in time. If I was smart I would have reduced my photo period, and over time gradually increased it again rather than subject everything in my tank to such intense lighting all at once. :redface:
