We recently had a pool installed in our backyard and the builder stated that we needed to bring a water sample by their office once a week for the first four weeks for (free) analysis. As I had already found this site and purchased a TF100 Test Kit prior to the completion of construction, I was interested in any deltas between their numbers and my own. The builder was using the BioGuard Accu-Scan system, but has recently switched to the newer BioGuard scanning system that does not use any strips.
To make things really interesting, I also had Leslie's Pool Supply test the water as well. All tests came from the same bottle of water.
So does anyone on this site have any info on how the new BioGuard system works? Any accuracy numbers? I'm assuming it is spectrophotometric as the sample spun and all test are performed simultaneously. I would really like to know if my CYA is really 120.

PS Sorry about the table, but I haven't found the code to change the font to fixed width.
