Fish Disease Diagnosis: Anti-bacterial, gram negative bacteria. Used when fish die for no apparent reason, when other medications are not helpful. Works well for Koi affected by Aeromonas (hole in the side) when mixed in feed.
Fish Disease Treatment: 1/4 teaspoonful per 30 gallons, every 3 days with a complete water change before each treatment. Or, 2 teaspoons per pound for Koi food. Feed for 14 – 21 days.
A large water change must be done after 3 days of treatment if used in water.
