Sprung Stunner problem

toadfarm · Jan 10, 2020

So I found a nice little "Sprung's Stunner" frag the other day. Nice little Chalice. I placed it in the bottom of my tank and within hours I noticed some bleaching. I then placed it in a shadier area. The color is almost completely gone gray/white, except for the polyps. They are still greenish. I'm very surprised that this bleached so quickly. Anybody ever have a frag turn that quickly? I'm running a Reefbreeders V2+ on pretty low percentages.

Honestly, I don't think your tank did that. I've never had a frag bleach that quickly, especially something as hardy as a stunner. And welcome!

The white was purple on Wednesday. The brown is where the green polyps were
All levels are 0 except nitrate at 10ppm

Stunner is generally a very hardy coral, I suspect just a random unexplained death or something with your chemistry is off. I have a huge colony baking under high PAR. I actually had my frag tank accidently drain and half of my stunner frags survived after being out of water for a couple hours. It pretty much is the fastest growing coral I own at that. Your frag looks like a goner but, I've seen this stuff bounce back so don't give up yet.
