my pool chemical levels are
i did a stain treatment on my pool last sunday.. everythings going good besides the chlor. ive been using pool calculator all week to raise my Chlor. 1ppm at a time. when i add the chlor. i will wait 1-2 hours and test agian and it still says 0. i finally dumped 2 gallons of 6% bleach in a couple days ago and it raised the chlor level to around 2-3 but yesturday it was back to 0. how long does iot take for absorbic acid to leave your pool? am i not keeping up with the amount of chlor. my pool takes?
