Need help with space invader chalice loosing skin

[Andersvendrup]

Hi guys.

just got my first chalice and ealier this day it looked fine, and then i looked again this evening, and i can see that it has lost some of its skin.

i can't seem to find if it gets too much light, or why it is loosing the skin.

just tested my params, and everything looks fine, only the ALK is a bit too high at 14, but none of the other corals are bothered by it.

has anyone else tryed this before and know how to fix it?

Thanks

Your other corals would be used to the alk of 14, but If this coral came from a tank with lower alk (my alk is 8.6 for example), then going to your tank of high alk might have caused this.

It could possible be a light issue

Would need more details on your tank to provide more guesses.

i run a maxspect razor 420R at 80% white, and 100% bllue.

The chalice is 5inches above the bottom of the tank.
is there anything else you need to know?

i have hammers placed higher in the tank with stronger light on em, and they thrive
