Corals growth/ happiness

[Robbie_b]

My 90 gal tank has been set up for 2 yrs now and ive just recently added corals about 3 months ago. I added a hammer, torch, bta and a candy cany trumpet. Everything was going good my torch is health as can be, my trumpet has been a roller coaster its good some days bad others, but i just notice my hammer hasnt been as happy and all coral growth slowed. I added a apex controller and wav pumps 2 months ago and since then he hasnt been fully open at all. I thought it was the wavs at first turned them down still nothing. I have 2 mars aqua 120w led lights set to 80% and my tank para are as followed:

Salinity 1.026
Temp 76.4
Alk 8.4
Cal 425
Mag 1500
Nitrate 0.2
Phos 0.015

Any tips or suggests i would greatly appreciate it!!

Have you tried dailing the lighting intensity?
Why is the mag high.
