I tried to order the Taylor 2006 kit on here to no avail. Says it is out of stock. So, I bought the 2005 Taylor kit instead from my local pool store. I live in Oregon, and we only have like 2 good swim months to enjoy a pool, so I can't wait until the middle of July to order a kit. I am going in there tomorrow to ask for a test tube that goes higher, he asked me yesterday if I wanted one that goes higher than 5, not knowing, I said no. He told me that usually only "commercial" pool people have them. I chucked and took my Taylor 2005. So, If I cannot get a chart that shows the color for cl 15, I will just keep putting bleach in until it is scarlet red I guess. I really want to avoid taking my water in there, but I will if I have to. Thanks for all the help on here.

Also, wondering if you can use the same BBB method on a hotub?
