bleaching

Hey all, My coraline algae that was once purpleish, is now bleaching white or a faded grey. I'm assuming it's my lighting because parts that have less light are still purple. Behind my anemone when it shrinks up, the coraline is still purple behind it. It started with white spots taking...

Over the past few weeks my clam has slowly been bleaching. The original spot was very very small but now covers two ruffles of the mantle. Also the parts that are bleached are pulled in. After reading a bunch there was only one article that seemed to have an answer, the cause being an infection...

I need some help. I have a mixed reef tank and a few weeks ago I noticed one of my SPS corals, seasons greetings montipora, turning white. He was a recent addition and I thought it was a one off. So I moved him, thinking lighting or flow. He kept getting worse. Around the same time I thought I...

Got some sps corals last night and placed them in the tank with some reef glue and one of them was already a little white at the base but this morning they all looked alot whiter, not sure what it could be because i have a other sps next to it like raptors claw and birdsnest and they look...

Just looking for input on a couple of cheap Acros I picked up from the LFS awhile back. It's a little hard to see from the picture, but the side facing the light fixture is almost completely devoid of polyps. They've been in the tank for about 4 months. Is this bleaching? Some sort of...

Hey everyone, I'm new to the forum. I purchased 2x SunSpect 165W LED fixtures with 90 degree optics probably around 6 months ago now. The fixtures are hung about 5-6 inches from the water's surface. I'm having some trouble dialing these suckers in and would prefer to avoid dishing out 100+...

Hi, Yesterday I noticed my trachyphyllia wasn't doing to well, everything seemed to be okay until yesterday I noticed it was either bleaching or showing skeleton. I moved it too a lower light and lower flow area of the tank so see if this helped as it had been sat in my sand below an MP10. Today...
