Anyone seen this before? My leptastrea had been growing well but it’s starting to show some skeleton at the bottom. Just did an ICP test and I’m pretty good on chemistry. Might need to check my nutrients as they tend to be pretty low. I don’t see anything crawling on it but I may dip it anyway. I have a predominately acropora tank and those are all looking good.
