Fritz: Maracyn Two

Maracyn Two powder is a broad-spectrum antibiotic developed for use in aquariums which has been shown to be effective against a number of pathogenic bacteria associated with ornamental fish disease. Due to its unique properties, it is absorbed by the fish through the skin. During the prescribed treatment, the concentration of the active ingredient in the fish fluids rises to a therapeutic level and is available to fight systemic infections susceptible to its action. 

Provides relief from bacterial infections such as fin and tail rot, popeye, septicemia, dropsy, internal infections, and other secondary infections, such as wounds from injuries or parasites.
