An update....I think my CYA measurement is off. Despite doing it twice and reading 40, I have to think it's more like 20. Chlorine is still disappearing fast but only during the day and I'm not showing any CC when I do have chlorine in there. After adding bleach and testing chlorine reading last night, it held the same reading this morning. Then it will be gone by the time I get home this evening.

I know I need to get more CYA in now but with the difficulty in knowing exactly where I'm at now, I'm not sure how much to add. I'm thinking about using pucks for a few days to try to maintain some consistent chlorine during the day while I'm at work and bring CYA up slowly until I see it holding. Thoughts?
