Yes, my K+ is right around 350. I dosed 4 ml of KZ potassium tonight, but I assume it is not that low.

Most corals are very happy, but I think something or some pest is after my first coral. It just took a turn for the worse yesterday, but all others are very happy...? Perhaps the new peppermint shrimp I bought last week is eating it?

First pic below is the damaged coral. Other seem fine. I have similar corals to the first that are not showing any damage. Any ideas?
