Fritz Maracyn® Two powder is a broad-spectrum
antibiotic (minocycline) developed for use in
aquariums. Due to its unique properties, it is absorbed
by the fish through the skin. During the prescribed
treatment, the concentration of minocycline in the fish
fluids rises to a therapeutic level and is available to
fight systemic infections susceptible to its action. It is
primarily effective against gram-negative pathogenic
organisms. Internal diseases are more difficult to
detect than external ones and early detection is almost
impossible. Symptoms of clamped fins, general
listlessness, not eating or other unusual behavior can
be caused by internal infections. All suspected
bacterial infections should be treated immediately.

Fritz Maracyn® Two is non-toxic to invertebrates.

in protein skimmers. Stop use of skimmer during
