## Questions & Answers

**Q: Has anyone used this for fin rot and does it work well?**
A: 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: Is this solution good for microscope labs?**
A: heck yeah!

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