Just to be clear, I've been checking the chlorine with the OTO kit. It looks like the local WalMart has the HTH kit and I'll pick one up this afternoon after work. The Taylor kit looks nice and I'll see about getting one ordered. I'll check the CYA level and post results tonight.

I tried to fill out the Pool Chart Entry Form but got hung up on my PF User ID. It's required and I can't seem to find it. I don't have access to My Profile yet, presumably because I'm still a Trial Member.

About the shock. The package doesn't list any other ingredients other than the dichlor. It just says 58.2% dichlor and 41.8% Other Ingredients. :-)
