I've been battling a hair algae outbreak for the last few months. When the algae growth exploded, I had a caulerpa crash in my refugium and noticed all my turbos and astrea snails dieing off. Water parameters look good. Other types of snails, urchins, shrimp, and crabs are all fine. I have been doinf water changes, dripping kalk, and maitaining good alk and pH. So......I decided to add another handfull of turbos and a few astrea. Acclimated them for two hours, but the same thing. By the next am they were either dead or close to death. One did last almost a week. I can't figure this out. Are these two types of snails more sensitive to PO4 than others?
