ajkochev Posted July 3, 2019 Share Posted July 3, 2019 I bought a large colony of zoas the other day. The colony looked health but the past couple of weeks more and more have refused to open and some are wasting away with what looks like cyano on them. I don't have cyano in the rest of the tank. Worried that a few more weeks I'll loose the colony. Any ideas? Quote Link to comment
mcarroll Posted July 3, 2019 Share Posted July 3, 2019 Pictures, test results for all parameters, as well as a brief history of the tank leading up to this point would all be helpful. 🙂 1 Quote Link to comment
Pjanssen Posted July 3, 2019 Share Posted July 3, 2019 Try an iodine dip, and try to blow the cyan off as often as possible. 1 Quote Link to comment
