Hi Gaston, It it extremely improbable that the swimming pool chemistry will work with CS. The color formed depends on reagents reacting with specific elements or compounds. No routine swimming pool chemistry tests for silver.
Your meter is probably closer to the truth. James Osbourne Holmes FTNWO -----Original Message----- From: G.
