chalice turned whitish brownish color

In all honesty Sollie, I have little to no experience with pc's personally. So I have never kept an echino under them. Take other's advice who do have them under pc's, as they have first hand knowledge.

 

ok ill jus see how it goes

 

how is it?

 

still look bad

 

any worse?

 

I had the same chalice, or at least same colored pattern and growth pattern. When I got it, it was a nice blue/green background with bright green polyps. Under my lighting, T5s, it turned to a light brown/green color. I've had it all over my tank, really low light, high light, medium etc., and it never colored back up. It has grown like crazy, but still nothing special to look at. I've had it for about 1.5 years.
