The pool store today said this:
This is what I got. I'm a newbie and am learning a lot but I think I have the testing down pat now.
CA 160 (turns purple at 120, turns blue at 160)
How can the TA be so different?
They told me my saturation index is -1.20 and the acceptable range is -.3 to +.3.
Is there anything I should be doing to "fix" the saturation index, or anything else? The water is clear, not quite sparkling, but not far off.
Thanks so much. We've totally enjoyed our new pool this first summer. My kids are having a ball!
