I have added 128 oz. of HD chlorine (11% available chlorine) and will retest in an hour. I brought this pool back from only a few inches of water (had algae & debris) removed as much as possible & refilled. Slammed pool and added about 10 oz. of Cya, I had left over. Waited for testing kit. Tested - 0 CYA at that time. Used pool calculator - added chlorine, massive amount of cya in stocking, calcium and borax, as advised. Chlorine has been added daily. Added nothing for 24-36 hours, after Arthur passed, I tested this a.m......(lot's of uv yesterday, none this a.m.) that's when I got 0 on my chlorine reading. I used the cya test kit to find my reading on it. Thanks Everyone!
I just recalculate and found I overdid the chlorine (panicked) but the UV's are pumping here so perhaps it will burn off....Also, it indicates I need to add more Calcium. As this is a new addition and in powder form, should I wait a few days before actually adding that?
