Connie- Here's an interesting bit of fluid trivia: If you have a water conditioner, additive, or medicine that says "One capful equals 10ml" then you can use that to figure ounces, because 10ml is approximately a third of a fluid ounce. Therefore 3 capsful would be one ounce. Steev P.S. All physicists and chemists are welcome to tell us if this is wrong. --- Connie Carlson <nwconniec@hotmail.com> wrote: > This may be a less-than-intelligent question, and I think it is primarily > directed at Tom so sorry if it is Tom, but is that one ounce of H2O2 per 10 > gallons of actual water or the rating of the tank?
