Thanks @bradleym for the info. I usually don’t test at night so that’s the reason I believe my alk is low. My dosing starts early in the morning. I ll check again tomorrow midday. I will add carbon asap and perform a water change. I am not sure I could get a fluconazole since most of the pet shops are closed due to Easter holidays but I will check tomorrow. What I got myself before was human grade ciprofloxacin which I don’t if I can use…can the treatment be effected in the display tank too?From what I see, there are three potential issues.
1. Your alkalinity is far too low, it should be at least 8. Please work on raising that slowly, it should take at least 24 hours to get up above 8 safely.
2. Your anemones could be fighting each other with chemicals. You should add a large amount of carbon as soon as possible to start absorbing those chemicals.
3. Your anemone may have an infection, would require treatment with fluconazole or similar. This usually best done in a quarantine tank if you have already established.
