No, they used a test strip with a bunch of dots on it and fed it into a small machine (probably a color analyzer). I used the black dot test with the kit I got from WalMart which tells me I need to add some stabilizer; that should help me get some more life out of my chlorine.

Once the trichlor tablets run out of the current frog cartridge, that thing is gone. Copper aside, I hate not knowing what is in my pool. I don't like the fact that it's "supposed to" keep FC between 0 and .5. That just doesn't sound right to me; and borderline unsanitary.

I have the Taylor K2006 kit on the way; should be here on Friday. I'll be going to liquid chlorine as soon as I get it re-piped. Thanks again for all your help, and for this wonderful forum/website. There's a lot of great information here!
