Provides relief from bacterial infections such as body fungus, gill disease, and popeye in fresh and saltwater aquariums.
Fritz Mardel 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.
Fritz Mardel Maracyn® is non-toxic to invertebrates. Follow dosage directions as detailed on the product packaging.
Directions & Dosage
