Day One Test results:
FC = 1
TC = 2
pH = 7.2
CH = 590 ppm
TA = 130 ppm
CYA = 100 ppm
The kit mentions using "unstabilized chlorine" for a time to reduce CYA. What is this? The other option listed was partially draining. I drained the pool to about an inch below the skimmer baskets. I added a gallon of unscented bleach, then refilled the pool.
Day Two Test Results:
CYA = 100 ppm
CH = 410 ppm
I can't remember the chlorine level. I drained the pool again, this time to three inches under the skimmer baskets (maybe four). At this point, I'm assuming I must have mis-read the CYA test the first day. I added a gallon and a half of unscented bleach, then refilled the pool and ran the pump all night.
Day Three Test Results:
CYA = 70 ppm
Chlorine = 0
pH = 7.2
At this point, I'm thinking I'm on the right track, but need to drain the same amount as the previous day to remove another 30 ppm. I did. I had NO bleach left, so I added a package of shock (active ingredients listed 99% chlorine, 1% "other"), then refilled the pool and ran the pump all night. The kids wanted to swim, and I had to sanitize.
Day Four Test Results:
CYA = 90 ppm
TC = 1.5
FC = 0
pH = 7.2
CH = 360 ppm
I'm surprised that one package of shock could actually increase the CYA by 20 ppm. Do I have a bad test kit? I bought it at Leslie's and it was a big one which he recommended (PS employee). I'm about out of CYA reagent already. Could our hose-water (fresh) have CYA in it? Why is the chlorine disappearing so quickly while I'm bringing down CYA? I don't have algae.
Thoughts? Thank you.
