Help , Chalice receeding (photo)

[Malifluous]

This is my first chalice, well i was told it is a chalice. If this is incorrect please let me know.

Right now i have it on the bottom of myy tank that is 24" away from 4- 39 watt t5's.
It has low flow. Can anyone see what I need to change by looking at these photos, the tank is 82 F Thanks for ur time.

As for temp your getting close to the high side. I usually run my tank at 78-79.

What is your Magnesium at? I found out that if mag is low it affects your chalices. Mag usually good around 1300-1500 ?

What is your ALK, Calcium, and Magnesium?

The chalice has only been in the tank for 4 days, would bad mg levels and alk already cause damage? I will test when i get home.

it just looks really stressed out. just ry and feed it. if it feeds it might be ok. i also heard about mag levels affecting chalices. idk if 4 days i enough tho. when i received my watermelon tyree chalice.. it shoed skeleton on the outside (being tightly closed). its now much better, and it ate last night. so i would say try and feed it. and do a waterchange (which may help with mag levels)
