Chalice Help Please!

[NanaReefer]

Under LED's on the sand bed. Not directly under the lights. All parameters stable and well balanced. Tissue seems to be receding from the outter edges.

Put it in shade. I lost a big chalice for no reason. I have a few chalices that do well and I couldn't figure out why.

ALK swing or low mag would be my first guess. Then I would venture into other things, best thing you can do is put it in low light/flow and cross your fingers.

Just tested my mag, ugh. To low for Chalice from what I've read at 1360. So I just dosed 2ml of Kents Tech-M. Will test again tomorrow. As for a shaded area, only place being is back under my overflow box. Thanks for the suggestions, I'm moving it.
