Kordon #37344 Methylene Blue-General Disease Prevention Tre

Q: Has anyone used this for fin rot and does it work well?

Use a few drops of this with a tsp of Epson salt per gallon and your fishy will heal. The methylene blue will stick to wound to provide oxygen to promote healing. Change 1/3 of the water per week.

Q: Can someone tell me if there are any additional ingredients ( preservatives,food colorings,additives,etc.) in this product?

label does not list any addl ingredients. Does state for aquarium fish use only. Not for human or food fish use.

Q: How much do you use per gal?

Please aquarium use, please follow the directions on the bottle, which says 1 tsp in 10 gallons produces a 3ppm solution. For 1 gallon, one tenth of a teaspoon is 0.5 mL, or about 10 drops. For other uses, please be aware that this is not a 1% solution. The manufacturer states that this is a 2.303% solution. This means that each drop contains 1.15mg (not 0.5mg).
