I don't remember. I know it was very low when I opened it. We have a mesh cover and a sump pump and had a good amount of precipitation so the water was diluted quite a bit. I used dichloride, as I always do, to open it and get my CYA back up. I did use a little too much as I usually keep it at around 40. Can't test my cc because I ran out and am waiting for it to come, but when I tested it 4 days ago, I had no cc, which is why I'm a little confused. The other thing that confuses me is that it was 7 after I add a gallon last night, 3 when I test it around 11am, and then stayed there all day- 85 and sunny. I would have expected it to drop some. I normally would have added bleach by now but I wanted to see what everyone had to say.
