I've been using the Taylor Watergram slide rule circular calculator to determine my saturation index and keep it within range.
However, using your pool calculator which takes into account salt, CYA and Borates which the Taylor calculator does not use, I get large discrepancies. In fact, according to the pool calculator, my csi is not within range, but according to the Taylor calculator, it is.
Can I assume that because the pool calculator is using more information, it is more accurate?
