As you can see in my post, my pool was filled 2 days ago. My teenager girls were swimming in it as it filled. I do not have leaves anywhere near my pool, and it is in full sun a lot of the day. I will be ordering a better test kit asap, but in the meanwhile all the local stores had at this time of the season is the htp test strips. I also have an old KH test from my fish tanks from a few years ago, but not sure that would still be valid results. Put 2 gallons of walmart 8.25% bleach in this morning. Came home this afternoon, FC still read 0. Added 1 more gallon, as per pool math site. Waited 30 min. At this point test strips are reading: FC 5 PH 7.5 TH 100 TA somewhere between 120 and 180. CYA 30 - 50. Waited another 30 min to 1 hour. Results were totally different. FC was down to 1. PH up to 8.4, and CYA 0. Added 2 more gallons of bleach. After another 30 min + FC 10+ PH 8.4, TA 180 TH100 CYA somewhere between the 30- 50 reading and the 100 reading. I know bleach is not supposed to raise CYA, but it is the only thing I have added to the pool? Also color went from completely clear before bleach added to a slightly yellow color, I assume because of the bleach color? So do I still need to get CYA? and is there another form of acid that would be readily available at this time of year in a small town?
