Help with dying colonies

[Wrench]

Update:

My problems seem to be subsiding. On Saturday I performed a FW dip with Seachem Coral Dip. I also setup a carbon reactor and adjusted my Mg levels to the higher end of the recommended range. As of tonight, my infected colonies are showing 80% or better recovery. Things are looking up ! I think the Carbon is what did it. Not sure what the problem was, but hopefully it's gone.

Thanks for the suggestions and help everyone

I run carbon 24/7 and my zoas look great. How often do you guys change out the carbon???

My tank has never seen carbon and i have had similar issues with zoas. I wonder if there is a connection there? I have considered using it because i have leathers in with sps but i never thought about the zoos.

How are your SPS doing with the Leathers??? I would run carbon just to be safe.

I have leathers, SPS, LPS & softies & run Purigen. Anyone having luck with dosing Vit C yet?
