Why is my zoa fading?

[Just John]

I have had a very dark blue zoa for a couple of months now and it has started to lose color over they last few days, turning into a lighter grey. It opens, it's just the color. All my parameters are the same and all other zoas have kept their color. Any idea why? Thanks

We maybe need some pictures and a full set of water parameters to see if we can help you out

Zoas can gain or lose color depending on the amount and kind of light

The LED light is not really bright with the AIO I have, but the colors have been fine for a couple of months and the past week or so some of them have started fading. Both of the ones in the picture are examples. The blue ones used to be dark blue. I used Chemiclean 3 days ago, but have changed some water since then. I have not heard of this side effect before and the blue ones started to lose color before then.

Ammonia - 0
pH - 8.1
