When I built my pool 1 yr ago, I was taught to use Chlorine pucks. I then found TFP and then use liquid chlorine ever since.
My question is my current CYA is 30ppm and I want to raise it to at least 40ppm. I have heard that the pucks increase CYA as well as sanitize. Would it be ok for me to use the pucks? I figure the bucket of pucks is just taking up room in my garage so why not kill two birds with one stone?
