chemiclean coral response

[Baldy]

I just got finished treating my tank with chemiclean to get rid of a cyano issue. Well it worked like a charm!

But I do have a question for those that have used it. My paly colony pulled its tentacles(?) in and left the mouth exposed after the first day as well as my hammer retracting a bit, and other slightchanges. second day after turning the skimmer and carbon back on The plays were back to normal along with most of the other coral. The only thing that's left is the hammer. Its retracted a bit more than usual. Its been 3 days since I dosed, and I did the 20% water change yesterday.

I'm not panicking yet, just wondering if any one else noticed changes like this using chemiclean.
