I found a source for ph test strips from Gallade chemical, www.galladechem.com.
I got 100 for $20. These test strips test 4.0-7.0. The problem with the pool test stips is the ph doesn't test low enough. I ran a test to see how accurate they are compared to a ph meter. The ph meter ran a tad bit higher. + .2 difference. I think it's close enough. I need to find my buffer tablets, so I can calibrate my meter too.
