Sodium Hexametaphosphate is the original "Calgon" formula plus perfume which was made in the US awhile back. It was reformulated due to the adverse effect the chemical had on the the microscopic flora in streams and rivers but can still be purchased from certain chemical supply houses. I believe it is used by people involved with pool cleaning.
