I have has this coral for 2 years. But today I noticed it's not looking good. Turning brown. I have excellent flow. Don't have any tests cause there expired. Will go out and get mag calcium and alk test tomorrow.

I can't tell with the blue lights but is it just shedding? Leathers can go through some nasty stages when shedding
