Hi all,
I opened my 16,000 gal pool the other day. first I dumped in 5 gal of 8.25% clorox, tested the CL level, got zero. put in three more gallons, tested CL, got zero. THe bleach smelled pretty strong when I was pouring so i would assume its fresh, and I just bought it at giant. I thought maybe my test kit went bad so I hauled a sample to the LPS and they read zero as well. PH read 7.7, CYA 4, TH 207, TA120, where did my chlorine go? My pool has an auto cover so it gets very little sunlight.
I then added 3 lbs of cal hypo, waited and hour, tested CL and got 0ppm! Next day (today) I added 3 lbs more cal hypo, waited an hour, tested and CL was 10 ppm. where did all that chlorine go? ???
