Thank You for replying. The remaining fish are not scratching anything.
The spots do not move at all.
I just had two more deaths. My lavander tang and my purple filamenta (sp).
The chromis mouth is closed. The clown fish still look awful and my sailfin looks the same.
I have done 40 gallons of water changes.
My water parm is:
Sal 1.025
nitrates <10
nitrites 0
amn 0
cal 390
phos 0
ph 8.3
alk 8
I put a ground probe on the tank.
