I've been using the Taylor wheel nomogram that comes with their professional FAS-DPD kit for calculating CSI, and using this to keep it between -0.3 and +0.3. Just by chance, I thought I would try the Pool Math spreadsheet, expecting the same results. Imagine my surprise at seeing some pretty significant differences.
The Talyor wheel uses CH, TA, pH and temperature (no CYA).
Pool math uses CH, TA, pH and CYA (no temperature).
Which do the experts consider the better measure?
