I grew up with a vinyl pool in Northern CA, however I just did whatever my dad told me to do..which most of the time kept the water decent looking but I didn't understand what was going on. Fast forward to adulthood and now I just re located to AZ into a new build (Both house and pool) I've added the pool specs to my signature.
Luckily I found this site, my new pool has been up and running for a few months now without trouble however I wanted to better understand the chemistry so I started lurking here. Luckily I read about the CYA build up that happens with trichlor and was able to just use the pucks until yesterday, when I tested the CYA at 40 and switched to liquid chlorine.
I do still have one question though: My pool came with a quick pure 3 Ozone, I know people on this site are not a fan, however seeing as it is there already I was wondering how this should affect my target chlorine levels? Should I just ignore it and leave any sanitation it performs as a safety net or should I take advantage and run slightly less chlorine?
