I am traveling next week to visit my wife's family. Two of them have pools, and I have the urge to bring my TF-100 along to see how well they keep up with their pool. I know both of the owners just dump based on pool store advice.
I think it would be interesting, but on the other hand, I may be horrified at what I find and have second thoughts about the kids getting in. Maybe at a minimum, I can convince them to get a good test kit.
So, do any of you test other's water?
