Hello everyone, it’s me again, and I’m having an issue with my favia. It’s receding for some reason and I lost a chalice bc of the same reason. I thought that it could’ve just been a fluke, but not anymore. It’s slowly losing skin, I don’t know what to do. Could I have low calcium? I can’t test for calcium right now bc my old test kit was way past it’s experation date. I’m getting a new one. Could anyone tell me what could be happening tho?
