Oxolinic acid is a hard to find antibacterial medication. It is known as a last chance treatment as it often provides results when other, more common treatments have failed.
Effective Against: Known to be highly effective against resistant aerosomas and bacterial hemorraghic septecemia which both tend to be deadly if not treated early. Also, effective against tail & fin rot and some columnaris strains.
Treatment: Can be dosed in the water for external diseases or used with food.
Water Treatment: Dose 1/4 teaspoon per 30 gallons water. Closely monitor fish while in treatment for signs of undue stress. 72 hours after dosing a complete water change is required as the medication will quickly decompose and water can become toxic if exposed longer. A complete water change cannot be overlooked. For this reason it is recommended to treat in a QT and not in a display tank.
Food Treatment: Mix 2 teaspoons Oxolinic Acid per pound of food. Feed for 14-21 days
