The problem here is that you may need to have your chlorine more than "maxed out", depending on your stabilizer level. If your CYA really is 150, then your chlorine has to be in the OTO orange range (20 - 40 ppm), which is not shown on your kit.

Also, if you are waiting to get the K2006, when you go to a local store . . . Don't! It's very, very rarely available locally, and they'll often try to sell the K2005 which is NOT the same, and NOT what you need. If you don't want to buy at Amazon, that's fine, but you will need to order online.
