Mushrooms???????? Help

[pilot_bell777]

My mushrooms have started shriveling up and are not opening in full bloom anymore......any ideas?

Water quality is great.

I added new lights 260W PCs but there were doing great after that, bigger than every.

I started using Calcium suplements, you think maybe too much calc in the water????? I got a Calc test kit today to test.....

I also moved them to a more shaded are of my tank but still the same...

All my other corals are doing great......

Mine did the same thing when I increased the light, they got big for a few days and then shrank. After about a week, they started getting used to the new light and came back. It is hard to tell though what exactly is wrong. I am not sur eif too much calcium would do that or not, but might be worth the check anyway.
