Maracyn-Two Mardel Laboratories, Inc.

For infections of:  Fin and Tail rot, Popeye, Gill Disease, Dropsy, Septicemia, secondary and internal infections.
*effective even when fish won't eat.
Indications: Maracyn-two is primarily effective against gram-negative bacteria.  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 and treatment with Maracyn-Two would be indicated.

Administration and Dosage: Maracyn-two should be dropped into the tank (not into the filter).  The tablets dissolve rapidly and circulate through the water.  An initital dosage of two tablets per ten gallons (37.85 liters) the first day is recommended so that the disease can be hit hard to start with and then finished off by the remainder of the treatment.  Second day through the fifth day, use one tablet per ten gallons of water.  Use of a hospital tank is recommended.
    It is not necessary to adjust pH, temperature or to make water changes if readings are in ideal range.  Maintain normal filtration and air.  If the activated carbon filter is over 5 days old, it may be left in place.  However, fresh carbon may reduce the activity of medications and should be removed.  Maracyn-Two is not toxic to invertebrates.
    Cloudiness may occur when using Maracyn-Two.  Once the full five day course of treatment is completed, a 25% water change is recommended.  This along iwth the addition of fresh activated carbon clears any remaining cloudiness.
*IMPORTANT: Be sure to treat for the full five days using the dosage recommended, even if the symptoms disappear after a few days.

Precautions:  Any sudden change in aquarium conditions can be hazardous.  Make changes gradually.  In tanks sealed with silicone, some staining may occur.  Do not overdose.  Keep this out of the reach of children.  For aquarium use only.  This product is intended for exclusive use with ornamental fish and/or other ornamental organisms and is not intended for use with fish for human consumption.

Active Ingredients: 10mg Minocycline/tablet

Notes from Mardel on biological filtration:  "Nitrobacter and Nitrosomonas are recognized as the primary beneficial bacteria present in the biological filtration system of any aquarium.  Some drugs which treat fish diseases and parasitic infestations are harmful to these 'good' bacteria.  When the biological filter is upset, there is a buildup of ammonia and nitrite concentrations resulting in fish distress and death.  Mardel products have been tested with known strains of these bacteria with no adverse effects noted.  When used as directed, they do not interfere with the biological filter."
