SPS polys are disappearing from the base

[chauda5]

Hi Reefers,

I have a RS reefer 425XL. I am running Aquaforest balling and Fauna Marin Color Elements. I am also dosing Fauna Marin amnino,UltraS and Ultra organic.
I have Vertex Zeovit Raactor, Vertex Omega 200i skimmer, JBJ Chiller.

The colors and health of my corals are fine except for 2 corals, the polyps on the base are disappearing. My tanks parameters are:
ALK-7.8
CA = 400
MG=1200

I do 10% weekly water change using FM professional sea salt.

I have started to dose KZ flatworm stop and coral booster 2 days ago.

Any feedback is much appreciated.

Thanks.



Thanks for the feedback

Have you already checked if the coral is affected with tissue eating flatworms ? From my experience this kind is really often affected.
