Hollywood Stunner Bleaching Rapidly?

[MoonRay]

Hey guys so kinda new to corals and I have this stunner who seems to be bleaching very rapidly.

Water Paramaters are:
Temp: 76
Salinity: 35
pH: 8.05
NH4: .25
NO2: 0
NO3: 0
PO4: 0
KH: 8
Calcium: 300 (even after dosing yesterday)
Mg: 1110 (I know it’s low)

Any suggestions or other thoughts what is going on?

One photo is yesterday, other is today.

What lighting type?
Have you tried a significant water change to bring values up?
How long have you had the piece?

Calcium and Mag quite low. My suggestion:

GRADUALLY. . . . Gradually, , , , , Gradually bring CA to 400, Mag to 1300, raise temp to 77-78, Lower those whites to 20% and blues to 75% and add a little Potassium and Aminos > > > > > > Gradually

There shouldn’t be any ammonia, that’s very concerning. But also you need detectable nitrate and phosphate, as well as higher cal and mag like Vetteguy said. Also less whites like they said too.

Just did a 25% with RO to help get rid of the ammonia and added some turbo calcium and magnesium.

I’ll see what’s can do on the lights. Thanks guys!

Need some nitrate and phosphate in that tank.

Let me guess, API ammonia test? How long has your tank been up?

Lots of parameters to correct as the guys have pointed out. I'm also guessing @Cell is right and that's an API ammonia reading. If so it's likely incorrect. Never the less, the water change is a good idea. Get Mg up, calcium up first then work on the NO3 and PO4 .
