gary3029 Posted August 2, 2008 Report Share Posted August 2, 2008 Hi With testing my pool twice a day and following the advice of the computer programme I use I have been able to get my readings into normal parameters: Tc 4ppm Fc 4ppm Ta 90ppm............. from over 200ppm!! Ph 7.2 Ch 120 Temp 76f cyanuric acid 40 saturation index on last nights test was -0.4. Now I found in my programme I can mess with the key varibles for saturation index and on the readings above if I increased ph to 7.6 I could get the saturation index to 0.0. This was even the case when I increased the TA, taking into acount the rise in PH. My point is given I have got my readings in their normal parameters should I now fine tune each day to get as near to a saturation index of 0.0 as I can or is that going to far?? Thanks Quote Link to comment Share on other sites More sharing options...
Strannik Posted August 2, 2008 Report Share Posted August 2, 2008 As long as it keeps within +- 0.5% it's all good. No need to be extremely accurate. Quote Link to comment Share on other sites More sharing options...
