To aid in general disease prevention, detoxification of fishes suffering from nitrite or cyanide poisoning and for use as a prophylaxis against fungus infections of fish spawns (eggs), add 10 drops per gallon (3.78 liters) or 1 teaspoon per 10 gallons (37.8 liters) of water (this produces 3 ppm methylene blue).
Remove carbon from filters but keep all filtration running. Replace carbon after completion of the treatment. Can be combined with Kordon's NovAqua Plus when used as a preventive, especially newly hatched fry.
For use as a dip, prepare a separate tank, add 5 teaspoon per 3 gallons of water (this produces 50 ppm methylene blue). Dip fish for no more than 10 seconds.
Methylene blue is toxic to plants and is harmful to biological filtration, preventing nitrification and resulting in a rapid rise in ammonia and/or nitrite levels. Treatment should be carried out in a separate hospital tank or other suitable container. Methylene blue can permanently color the silicone sealant in aquariums.
