Melting?

[Shep]

So I keep seeing people use this term but I have no idea what it means. Could someone explain what it means?



Thanks!

Best to be left innocent! You'll know it when you see it!

I just mean if you had seen one of your zoas , which had been growing nicely, slow start to diminish to a nub and disappear, you would know.
Be grateful it hasn't happened to one of your corals.
