I was looking for CYA on Leslie's website to compare prices with the other local stores (they are EXPENSIVE) and I came across this so-called pH Lock. I can't see what chemicals are in it, so I don't know what it is. Has anyone heard of this before? I'm not going to use it, just wondering if anyone can shed some light on this "magical potion." http://www.lesliespool.com/leslies-1...1-qt/14125.htm
According to their website, "pH Lock will instantly lower or raise the pH to the correct range of 7.2 to 7.8"
