My small half dollar size Mushroom Leather has been getting a brown coating on top of it recently. I just got it about a week ago. Any tips on what I can do, or something I'm missing. I had it up higher in tank, and was told this best location, but didn't know if there is something else I'm missing to do with this coral. It just doesn't seem to be looking that great and now this brown coating on top of it. Any ideas or tips?
