Fritz Maracyn Two 24 pack
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. Maracyn® Two is primarily effective against gram-negative pathogenic organisms. Internal diseases are more difficult to detect than external ones as early detection is almost impossible. It is also potentially effective against some gram-positive and fungal infections, making it our most broad-spectrum treatment, and a great first choice of medication when the cause of disease is unknown.
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. Symptoms of possible bacterial infection can include clamped fins, general listlessness, degradation of tissue on fins, suppressed appetite or other unusual behavior can be caused by internal infections. All suspected bacterial infections should be treated immediately. Consult a veterinarian or fish expert for assistance in diagnosis of disease causing organisms and treatment options.
