Zoa losing color

[SahuaritaMike]

I have an orange skirt zoa and it sits lower in my tank, and I noticed today that some of its skirt and orange centers are fading to a brown color could it be get too much or not enough light. all levels are good. The only thing I can think of is this last weekend I did about a 7 gallon water change and my salinity went from 1.026 to 1.023-4 could that be the problem? Any info would be great thanks.

higher light the better. Are they one ones you got from me? with the longer skirts?
