Bubble Coral, Help!

[amylora]

I have a bubble coral, I believe it is "Plerogyra Sinuosa", which has not been happy lately. I have had it for about 3 months, and the last 3 weeks it hasn't been doing so well.

At first, I just noticed each day bubble would come out less and less, and now I am seeing a yellow-green film growing on the skeleton of the bubbles. The skeleton also seems very fragile and week.

I do not have a reef test kit yet, so I do not know my exact levels. All my other corals are doing just fine.

One thing I particularily noticed, my bubbles began to be unhappy just a day or so after I added an anemone to my tank. (I decided to get rid of this anemone and took it back to the fish store.)

Please help me if you have any advice, I could sure use it. Thanks!!!

Need more info than that. One thing for sure is that most bubble corals nowadays do not like strong light. So if you got yours under halides move them further down or to the side. But this might stress them out even more.
