Hello TFP Forum! I've been following the forum for about a year, and this is my first post.
We opened the pool two days ago to cloudy water, and testing with TFT-100 produced the following:
free chlorine: 0
combined chlorine: 0
Saturday I added 6 lb of stabilizer followed by 3 lb cal-hypo. Tested for chlorine a few hours later, and no free or combined chlorine was detected.
Yesterday I added 4 gal of 12.5% liquid chlorine and tested 2 hrs later - free chlorine: 1ppm; combined chlorine: 7 ppm.
I tested again early this morning, and all free and combined chlorine was gone,
I then added 4 more gal of 12.5% chlorine and tested 2 hr later - free c: <1; combined c: 7ppm.
should I continue this pattern or change my approach?
