Welcome to our forum.
450 gallons and I added 6 cups of salt. Plus they added salt when we filled the tub. I'm going to call the dealer Monday.
The salt level is around 1000 ppm. When they filled the tub, the water went through a large blue canister that they added salt to. I have since added 6 cups of salt. How do I check for phosphates?
I'm now at 2000 ppm after adding a total of 9 cups of salt. I'm currently in the bottom 10% of the green band.
