Last week I started to notice the odor of bleach or high cc. I have always had 0-.05 testing results. I will mention my water is super clear. It did get very slightly hazy a month ago but numbers were in range. I brought the chlorine level up and it went away the next day. I am on my 4th day of a slam and my free chlorine levels are not going down over night at all.
I am still getting readings of 1.5-3 cc. I have a 7 month old TF 100 test kit. I am beginning to wonder if one of the regents are bad. I did replace the 0870 powder as it was getting gray. My latest test results this morning were
ph 7.5 before slam
I would also mention my CYA had dropped from about 75 to about 20 over the winter. We have had near record rainfall in Southern Florida this winter. I have also been leaving the solar cover off during the day and putting on at night. Thanks, Jim
