Defend Treatment for disease of aquarium fish caused by fungi, protozoans, bacterial and more. Use MICROBE-LIFT/Defend to control, prevent and treat disease of aquarium and ornamental pond fish caused by fungi, protozoans, flukes and bacteria. MICROBE-LIFT/Defend is a salt-free formulation. Ingredients Water and Formaldehyde (<3%) and Methanol. Warning: Do not use MICROBE-LIFT/Defend with any other medications or treatments. Purpose To treat and prevent disease of fish caused by fungus infections (typically, whitish, cottony patches on fish skin and/or fins), and by other external diseases caused by bacteria (mouth "fungus" and fin-and-tail-rot) or protozoans ("ich"). Directions Dose at the rate of one teaspoon (5 mL) for each 10 gallons (38 L) of water, or 1 fl.oz. per 60 gallons (227 L). Prior to the initial use of MICROBE-LIFT/Defend a partial water change, of 25% or more should be made. Carbon filtration must be removed during treatment (CAUTION: Do not stop other filtration!). Dosage may be repeated, following the recommended water change, every 24 hours. MICROBE-LIFT/Defend is best used in a separate quarantine/ treatment (Q/T) tank. If after three treatments, signs of the disease being treated persist, perform a large water change, replace the carbon filtration, and consider using an alternative treatment. Cautions & Contraindications Do not use with permanganate-based treatments. Observe fish closely during the course of the treatment and perform massive water changes, as needed, if signs of severe stress (e.g. rapid respiration, "piping" at the surface) are noted.
