Blue Planet Fungus Cure is an effective treatment for fungal diseases in freshwater and tropical freshwater aquarium fish and will not affect aquarium plants and fish when used at the recommended dose rate. Fungal diseases are common in freshwater fish and are recognised by white or grey threads on the skin or fins which may thicken until they resemble tufts of cotton wool (pin head size) on the fish's body and fins. Unless prompt action is taken fatalities will occur. HOW TO USE: Shake bottle vigorously before each application. Use at a rate of 5mL per 20 litres of aquarium water. For Tetra species, baby fish and scaleless fish (loaches etc.) use at the reduced rate of 5mL per 40 litres of aquarium water. Treatment should be repeated after 3 days. Contains: 2.00mg/mL Acriflavine, 0.40mg/mL Malachite Green.
