Hey folks! I offered to test a friend's pool water and it's so bad I'm not sure what to tell him. His CYA is 100 and only had 1.5 of free chlorine! I know how to help with that part, but he had 0 alkalinity and 0 pH. I've never seen that before! I use the Taylor 2006 and have for a while, so I'm confident in my testing. At least for my pool! LOL I just don't know if I should tell him to add baking soda first or borax? Pool math recommended 1096 lbs of borax and 7.13 lbs of baking soda. That's a lot of borax. And should he slam it first or get the pH up? I've never tested water with the numbers so off, so I'm confused. Any help is very much appreciated!
