Thank you all. I DO understand that you can only give me your advice and can't read my total chlorine without the K2006. I never asked you to find a way around it or guess. What I just didn't appreciate was a moderator coming down hard on me (or changing the name of the thread). This pool has been a good intro to the whole process. I especially never knew that places like Leslie's were like when I'd take my car to Jiffy Lube for an oil change and they'd try to flush my radiator for $300.
