I had an algea problem so cut my fowlr lights back from 12 hrs to 7-8 hours. Also I changed out the crappy bulbs to ati bulbs. (4 bulb t5) well I recently noticed my coraline on the glass and all over my rocks, pump, everything is turning white. Just curious if this is bad or jut because the lack of light. I will be picking up my first corals at the FFM so my light cycle will go back up to 12. Just curious if this coraline color change is a problem. Thanks everyone
