Benefit: When used at the recommended dosage Maracyn maintains a therapeutic level of the drug within the aquarium. Maracyn does not color the water and will not interfere with the biological filter. Maracyn Powder Saltwater contains B complex vitamins to stimulate metabolism and improve the appetite of fish. The powder dissolves rapidly on contact with water, and an active level of antibiotic is distributed within the tank in a matter of minutes.

Use: Maracyn is primarily effective against gram-positive pathogenic microorganisms. 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. Maracyn is recommended for the treatment of Columnaris (Body fungus), Popeye, Gill disease and Fin and Tail rot. All suspected bacterial infections should be treated immediately. Powder should be administered into the tank (not the filter). The powder dissolves rapidly and circulates through the water. Use of a hospital tank is recommended. Use one packet per 20 gallons of water and repeat every 24 hours for 5 days. After treatment Maracyn can be removed by water changes or fresh activated carbon.

Active Ingredients: Each packet contains 400mg Erythromycin activity; 15.00mg Pantothenic acid, 8.60mg Riboflavin, 2.60mg Thiamine mononitrate, 2.60mg Pyridoxine hydrochloride.
