Acro went from bleached to brown

[tencwhiskey]

My acropora bleached suddenly about two months ago or so and I just left in the tank moved it lower, thinking maybe I had too much light.
It's been slowly browning and now is dark brown. Any ideas as what is going on?

Well as long as it's tissue is turning brown and it isn't algae it has taken up the symbosis algae and is on its way to recovery. Do you have a pic of it?

 

[tencwhiskey]

Can't get a great picture with this phone

Usually means it's recovering. Will probably turn green next.

What are your parameters like?

 

[rajkovich207]

Yea it's hard to tell if it's glass but my money is on its recovery

Look up--"zooxanthellae"

A bleached coral is not dead, but will die if it's life line zooxanthellae algae doesn't return to its skeleton when proper params are restored.

Did you by any chance just use a product in your tank claiming to brighten corals? This could be the culprit as most of those products are just boosting your zooxanthellae population (which can be devastating if population is too high)

A lot of the Red Sea test kits have interesting facts in the booklets about this symbiotic relationship between the coral and zooxanthellae, and how your parameter levels effect the color and overall vitality of your coral.
