In order
to calculate chemical treatment cost you need to know
the ppm* of the product used to treat your system. This
number is not the tracer that you test for, i.e. phosphate
(PO4) or Molybdate (Mo) ppm* but the entire chemical
product dosage. An example would be a tracer of PO4
ranging from 10-20 ppm* with a chemical product dosage
of 200-400 ppm*. Use 200 ppm* for a low cost calculation
and 400 ppm* for a high cost calculation.
