- Treats bacterial infections
- Safe for aquarium plants
- Safe for shrimp, snails, and other invertebrates
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.
The savings come in the 24-count package or larger over the traditional API Erythromycin. Each packet treats 10 gallons. The 60-gram bulk container treats 1,000 gallons. We recommend using an air stone in the aquarium when treating with Maracyn.
After failing aquarium salts and Pimafix/Melafix, I resorted to antibiotics. The fish survived and thrived.
