Looking for clarification. I used "waterbear's" 2008 posted calculations to determine the quantity of Borax and MA needed to adjust my pool to the desired borate level. Just for grins, I hopped over to the pool calculator and ran a comparative. I noticed a 27-29% higher differential with waterbear's data vs. the pool calculator. I also used a couple of other software apps that agreed with the pool calculator.
While not a huge issue, just curious why there would be any differential. Thoughts?
