Need help chalice coral tissue receding

[Pipo5]

So i went away for a weekend when i came back found my purple chalice under my raja rampage chalice. They both were stinging each other but my raja rampage had skeleton showing but in a week it bounced back like nothing happened. Now my purple chalice at first had almost no skeleton showing at all and now over time its ben loosing its tissue. Don't know if just cutting the dead stuff off will be enough or should i also dip it i just don't won't to lose the hole coral?

Dead skeleton is harmless- don't cut it off. That's a lot of handling and potential trauma to remove something that's essentially rock.

Dipping the coral is probably a good idea. A pic under white lights might also be good, in case there's something going on that we can spot.

I notice that the damaged side is facing towards some other corals. It might be smart to move it a couple inches towards the glass, in case those corals are attacking it. Alternately, spin it slightly, and see if the damage starts up in a new spot.

Man, that’s tuff.
I’m also a chalice lover.
I have had luck dipping them in an iodine based coral dips, I think I have seachems brand.

This is tissue loss also referred to as necrosis and can be caused by a variety of things to check below and can be as simple as flow or light and things overlooked.
Some possible triggers of infection are:
- Alkalinity spike
- Temperature spike
- Salinity spike
- Low dissolved oxygen
- Poor water quality related with phosphate levels up to 5 ppm
- Change in water flow
- Additions of sand
- Changes in brand of salt
- Bad test kits giving faulty results
- Levels of minor elements such as Iodine, Potassium, Strontium
- Light intensity
- Addition of new corals

It's been in the same spot growing fine. Actually, one of my faster growing chalice until it touched the raja rampage. I just moved it this it under white light

I have typically used seachem coral disinfectant. If all you have readily available is revive, I would try that and monitor for a few days. I wouldn’t be afraid of using revive.
I would also check LFS in your area and see what iodine based dips they have.

Consider using Restor, it tends to do a lot of good for LPS when losing tissue. I've had a lot of success with it helping everything from Euphyllia to chalices. Also, a vendor a while ago told me for STN they recommend tea tree oil; I've used it since a few times and it seemed to stop the progression of the disease without it being too harsh. Beautiful coral, crossing fingers that it makes it!
