This is my second season in "the program". After regular water adjustment and sanitation has become like a second nature, I decided this season to have top quality water by adding borates and salt, trusting positive reports from other users regarding these two chemicals in their proper dosage. I did a bucket test and couldn't taste salt at 3000 ppm.
I added borates to 50 ppm using the dosage calculated by Jason and chem geek (93 w% Boric Acid and 7 w% Borax.) I checked the level with LaMotte insta - test strips and I got it right.
I checked my pre-existing salt level with Aquacheck's salt test strips. I got 500 ppm. According to the pool calculator, adding 400 Lbs of salt should raise the level to 2634. However, after adding 400 Lbs I got 3820 ppm and I can certainly taste some salt. What happened?
