Why do my grandis palys look like this?

The ones at top are like folding in on four corners. The ones at bottom look better but still not perfect. Why is the color fading? I have a razor X 100 and blues are at 77 whites 57 is this ok? I've had these palys for years and always looked brown and decent. My main tank was torn down and I moved them to a standby tank for seven months. They changed color and folded eventually with This light. Six months ago, I moved them back to a new tank with a fresh cycle. They never looked great since. It completed the cycle several months ago. Nitrates at 20 and no nitrites or ammonia. I am using phoenix tap water but was before too.

Other than not super great colour, I don't see anything wrong. Do you have a picture of when they were what you think they should be? I know with mine, they react very poorly to being moved and take months to bounce back. They also don't love blasting light, and do better in the shadow of something else.
