Well today's tests are still a bit of a mystery, but a bit more label reading may have suggested something I should have considered. First the test results..
No chlorine (and therefore, I assume, no Free Chlorine??)
PH still very close to 7.5
TA 60
I still get no reading on the CYA Test....
Here is where the reading comes in....my CYA is Poolife Stabilizer and Conditioner, a 4lb container.
To date, I have added about 1.5 lbs and just started another .5 lb in a sock (this is right at one half of the 4lb container).
The container suggests that for a 20K gallon pool, I should add 3.5lbs of CYA to get to 20ppm. If I add the entire bottle, I should be somewhere around 25ppm.
The pool calculator says I need to add 53oz by weight to reach 20ppm.
Assuming 16oz to a pound (by weight), I can see I have not added nearly enough CYA to reach 20ppm.
I have two socks of CYA going right now (one is about to exhaust itself).
Is continuing this two sock approach the right thing to do (giving each sock a squeeze once or twice a day)?
Thanks all for any ideas!
I continue to add about one half of a bottle of bleach each night after sundown.
Pool water still looks good.
The process continues....
