To quote Ted: "When you do buy methylene blue, the concentration may sometimes be sold as 1%, in which case you may need to dilute this to 0.1% concentration. So if a 100 cc of 1% methylene blue is bought from a local aquarium shops, I may have to add 900 cc of water (which totals) 1000 cc or 1 liter at 0.1% concentration." - end of quotation
So if you had a 2.303% solution you would use just under 50cc of 2.303% methylene blue and 900cc of water. Does that sound right?
