coral chalice health

So my coral is not doing too hot, been on a downfall for past 3 months...it was on bottom of tank in bottom right corner and last night moved up to top of tank. lights are ai sol whites. parameters

mag-1300
calc-520
ph-8.0
alk-7.0
phosphate-minimal
salinity 1.025

know my calc is a little high, maybe can't process the calcium, maybe it's just time for this coral to go...

lost my protein skimmer about 2mo ago as waiting for replacement, but have been doing water changes every week, been running carbon and gfo for about 7 months...tank been up for about 3 years, coral probably a yr old at least.

also wanted to show my anemone off, thanks

thoughts?

 

Maybe get the mushrooms away from it. Chalices also like higher mag. Salinity should be higher as well.

 

There were no mushrooms by it on the bottom, mushrooms just came by it yesterday as I put it higher up, was on bottom right corner on Sandbed with really nothing around it

 

OK, then, alk is too low, salinity should be higher and chalices thrive in higher magnesium. Also seems odd that calcium is so high at 1.025.
