I wouldn't run a tank without carbon personally
I've ran carbon for years and have never had any of the issues mentioned. I use ROX 0.8 which is a premium carbon.
25 years and counting and never an issue using carbon. I run small quantities 24/7/365 and change it when I remember.
Do you use "Special" Carbon?
My LFS sells Regular Carbon and also "Reef Carbon"
I use the Freshwater Carbon that comes in Silver Packets from Tetra.
Is that why my Corals are Dying?
Should I use a different type of Carbon?
They most certainly have pests, as all corals can. I'm not aware of any pests that specifically attack only chalices (although they probably exist), however I've seen several predators come in on them before. 'Chalices' should be dipped and QT'd along with all other corals, IMO.I am told Chalices have no Pests.
What Pests do they have?
Chalice eating Nudibranchs?
