I recently had a BAD cyano outbreak and began to treat it by doing a 40% water change while sucking out as much of the cyano as possible, blacking out the tank (on day 2 of black out), and using 2.5mg/l of azithromycin. Has anyone used this antibiotic before? I know that erithromycin is the standard antibiotic that is used to treat cyano but i assumed both of these antibiotics are of the same famly. Does anyone have any experience with this in particular medication used for treating cyano?
