Carl made a little typo. We recommend the Taylor K-2006, not the K-2005.
I also do things just a little differently than he does. I don't check my CYA weekly. After I get my CYA where I want it early in the swim season, I don't test it anymore that summer. I can do that since I don't use any forms of stabilized chlorine like trichlor pucks or dichlor powder. I only use bleach.
