Mardel Maracyn Bacterial Fish Treatment

Highly effective for common bacterial infections in fish

Mardel Maracyn is a specially compounded, erythromycin-based antibiotic medication which has been shown to be effective against a number of pathogenic bacteria associated with ornamental fish disease. Erythromycin is a broad-spectrum antibiotic and is primarily effective against gram-positive pathogenic organisms. Almost all nitrifying bacteria are gram-negative, so the beneficial biological filter should not be harmed by treatment with Maracyn, and you shouldn't see a spike in ammonia or nitrite. 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 and may indicate a need for immediate treatment.
