Good Afternoon All, First, I have found this site to be a great resource of information and advice. I have lurked for some time while making a decision in what Spa I should purchase. I have a Klondiker LSE and I am trying to figure out the relationship between the Free Bromine, ORP meter reading, and the Salt Level. The Onzen manual states that the ORP meter measures the "sanitizer" level. So, since the Onzen system creates Bromine (a sanitizer) the ORP reading must have something to do with the amount of Bromine in the water - I think. From my experience I have not noticed a relationship between the ORP reading and the Free Bromine level that my test strips measure. Can anyone help me understand the relationship between the salt level, the free bromine level, and the ORP meter reading? Thanks, Doug
