PLEASE HELP!! my zoas are dying

[Papadovak]

Over the past two weeks I've noticed my zoas are starting to die off I've dipped them all one by one and found nothing. First they close then start to turn brown/black then just disintegrate. All the other coral seems fine. I've noticed a reddish colored film on my zoos but idk what to do?!
SG. 1.023
NO3. 0.0
Po4. 0.0
CA. 430
Ph. 8.2
Temp. 79
Any help is greatly appreciated! I don't want to lose them all.

Have u try to dip in hydrogen peroxide? U can find at local pharmacy.
I had a very good rate of em coming back. I used 50/50 with tank water for 3 mins. Let it bubble out, very small bubbles, re dip with just tank water and go back to the tank. Keep it in shades, low flow and check it in 3-5 days....it i see polyp start to open , that's a good sign of recover. ...
Good luck...

Any particular reason you run you salinity at 1.023??? Optimal salinity is at 1.025... Also what is your alk and mag at? Always need to know what the alk, cal and mag are at, those three are the most important parameters that should be checked and kept in check
