Provides Relief from Bacterial Infections in Fresh and Salt Water Aquariums for: Body Fungus, Gill Disease, and Popeye.

Maracyn is a specially compounded broad-spectrum antibiotic (erythromycin) which has been shown to be effective against a number of pathogenic bacteria associated with ornamental fish disease. It was developed for complete but gradual dissolution in water. It is primarily effective against gram-positive pathogenic organisms. Symptoms of clamped fins, swollen eyes, heavy or rapid breathing, patchy coloration, change in swimming behavior or corner hiding can be signs of possible bacterial infection.

All suspected bacterial infections should be treated immediately.

Maracyn is non-toxic to invertebrates.
