Ok...the stuff came early in the week. Last night I added the polyquat and will do so again tomorrow. Got the ph down to 7.0-7.2 and the chlorine to 0.4 so decided tonight it was time. Used just about 3 pounds of ascorbic acid. Simply amazing. What I thought was minimal staining turned out to be more pronounced as we could see the streaks of clear pool appear on the walls and floor. In 45 min it was clear! Added the Pink Stuff and stuck the 4.0 ppm culator in the skimmer sock lining the skimmer basket. Hopeful it will continue to look this good. Going to add a little pink stuff whenever I add water. May keep the pack in the skimmer full time and replace every 30 days.

Tomorrow night will raise ph a little with borax and then if it's good on Monday add bleach. I assume I want to add enough to get chlorine to 3-6 ppm ( current cya 40-50) but it likely won't be enough when I retest next day because of vit c? Thanks for your help.
