"It would have twice as many particles, so it should be twice as effective."
20 ppm doesn't automatically mean twice as many particles (as 10 ppm), only twice as much silver. You could have one pebble of silver at the bottom of the container and still have 20 ppm. ppm is a measurement of the total quantity (of silver in this case), and is not relevant to the number of particles. __________________________________________________ Do You Yahoo!?
