A few years ago I opened my first pool, and the forum was a tremendous help.
Four summers later, I have a crystal clear pool, with the use of bleach, borax, and baking soda.
I'm at the next phase, though, in that I have never added CYA, and I think I need some...
It's at zero. And I'm pumping chlorine in...
Four years ago, my then girlfriend and mother were running the pool. Their idea was just too throw chemicals down and big pucks in the pool. Once I found this website and started doing some testing, I found the cya level was over 100. Through a ton of work, advice and patience, I cleared the pool, but now I'm gun shy about cya.
I've done some reading, but I need some direct advice.
What is my best method to start with? Are there good brands over others? Should I use a puck in a sock in the skimmer? Should I use liquid?
I used pool math, but it's a little conflicted... Or I'm out of practice.
Thank you for your help!
