i think that zoa melting is related to water conditons, i heard that zoas grow more successfully in water rich in nutrients and macro elements, my theory is that very clean water with 0 nitrate and 0 phosphate could be harmful for zoas. those elements are helpful for xooxanthellas and cellular growth.
Vitamin c is a source of carbon which is one of the macro elements as Nitrogen and phosphates essentials for coral growth and metabolism. This may explain the amelioration seen after the addition of vitamin C
I started lately to add nitrogen compounds to raise slightly my nitrate level which was zero as i had the problem of melting despite excellent water parameters
