Water temp is 42 degrees. Water is clear.
CH- 350 (some calcium deposits on some tiles & deposits on rocks in water under waterfall)
Borate test strip shows 15 but I haven't added any.
Should I worry about the CYA in winter when water temp is cold & how will the cold water affect my results?
I just added acid & bleach according to pool math calculator. I do want to add Borax after reading about the positives in the forum. Should I wait till water warms up for borax or is now a good time? I plan on adding salt tomorrow.....Thanks in advance for your responses!
