Chalice turned all green

[Nuocmam]

Anybody ever have a chalice turn all green on them? I've had this piece for over a year turn all green.

I had a couple of purple wm's that morphed mostly green when I switched from MH's to T-5's. They are getting their purple color back after 6 mths.

Mine is a purple watermelon type too. It came from a tank running halides but kept color for a year. It's weird like the rim just took over the whole thing.
