My preferred use of Methylene Blue is a bath.
To prepare this bath I use 1 teaspoon 2.303% solution per 5 gallons (double dose) in a bath of aquarium water from the tank the fish you wish to treat came from, I usually use about a ½ gallon of water, however you may use less.
Measurement of the Methylene Blue does not need to be precise as this bath should be used for about 30 minutes (although do not grossly overdose).
