Directions & Dosage
The use of a hospital tank is recommended. It is always wise to check your water quality levels to ensure they are within their acceptable ranges before administering any water treatment. No water changes, pH or temperature adjustments necessary if readings are in ideal range. Maintain normal filtration and air.

Use 1/2 capful (2.5 mL) per 10 gallons of water. Repeat as needed for not more than 5 days. It is suggested to always increase tank aeration during treatment to ensure an adequate oxygen supply for sick fish. Switch off UV sterilizers during treatment. Should fish exhibit signs of distress neutralize the medication by using an aquarium dechlorinator, such as FritzGuard, Fritz A.C.C.R. or Fritz Complete. Follow the manufacturer’s directions for dosing.
