Dietitian Posted February 21, 2010 Report Share Posted February 21, 2010 The point of pool water maintenance is to disinfect/protect from pathogens, but also to protect our spas from corrosion and calcium deposits. With this in mind, Evian Water, when measured with a Taylor kit, indicates the following: TA: 340 CH: 240 FC: 0 CC: 0 PH: 7.2 (Actual listed on bottle: 7.18) This yields a CSI of 0.08, which may be close to 0.00 with 7.18 PH. City water has the following stats: PH 8.6+ TA: 90 CH: 90 FC: 1 CC: 1 CSI: 0.60 Would this indicate that my hot tub water is not only safe to drink, but is less corrosive / calcifying for my teeth than city water?
