My green button polyps stopped expanding and lost their color in December.

It does not look like they are coming back. What do I do? Do I take these colonies out of the water, since I am starting to have some algae growth. I think they are dying.

I read something about this situation in Borneman book, but he siad they may come back.

I just happend. I do not know if it was the IO salt or not.

What do you think I should do? At the same time, my mushroooms started to die. Something is definitley wrong.

Need Help!

Thanks,
