John,
It isn't the ppm that is so important (although 5 - 10ppm has shown to be
ideal in most cases), it is particle size. The smaller the better... and the
stronger the solution.

Hello
If weaker CS is better than a stronger CS could somebody please tell us
how a 5ppm is more effective than a 10ppm? Thank you. John.
