But then how is my free chlorine level at 22 still? Not questioning your judgement but trying to understand this. I have not done the sock method before.
Then that means you little to no CYA in the water and need to add some. So I would grab some granular stabilizer and use the sock pre-soaking method to add about 30 ppm of stabilizer. If you've not done the sock method before let us know.
Without stabilizer, all the chlorine you add to the water gets burned off by the sun extremely fast preventing it from doing it's job.
