I think your damsel will be fine. They can survive almost everything. I normally say they survive everything but you found something they can's survive in. Also keep us updated on what you find out about the product. I and i am sure others would like to know what you used that was saltwater safe, but turned to be a deadly substance. As for your snails, my guess is the hermits killed them. Hermits can't make their own shells, they steal them from other animals that do. If you don't have extra shells in the tank for the hermits picking they tend to kill the snails for theres. I also feed my cuc sometimes....I sometimes wonder how much there is actually to clean up in a tank and i like you don't want them to starve.
