I got the distilled water and used the shot glass method and Cl is 6. Not as high as I expected, but today was sunny and warm, plus the trees are dropping a ton of seeds in the pool. I haven't added any chlorine sine the first day.

I didn't add any borax tonight but will in the am, just to get it up to a measurable amount. I am thinking about 1/4 box at a time? Do I dissolve it first or just broadcast it?

I am excited that the Alk is down to 140. So once the pH comes back up I will repeat the process to get it down further. I am thing in the range of 80-100.
