What's wrong with my Frogspawn?

It started changing color in begining of march i think. i got it from someone elses tank were it was placed the same way up were it is in my tank with the same light fixture, but his bulbs were
front:
PowerGlo 18000K
AquaZ blue pro
Giessman Aquablue Plus
AquaZ blue Pro
PowerGlo 18000K

I use reef crystals for my water and its mixed with RO/DI water.
Params are:
SG: 1.026
PH: 8.2
Alkalinity: 8
Calcium: 440-460
Zero nitrites, nitrates, ammonia, phosphates

i dont test for MG because i dont have a test kit for it.

 

Try putting down lower. Also do you feed mysis shrimp? mine love eating it. I just make sure it floats over towards the FS and they are good and grabbing it with their tentacles

 

If you can speak to he person you got it from, try asking how was his the salinity on his tank, yours seems a little high and could be the problem. Only if you had it for just a week
or 2 from where started to change, then again if it still looks healthy!? might start to look alright after it gets used to all the changes. are those AquaZ blue pro, Giessman Aquablue Plus, lights blue or are they more purple 460nm, or 420's?? since different manufacturers make practically the same spectrums, sorry; maybe I should of specified, name brand don't tell me a whole lot
