Ok so I added one four pound box of borax just to see how much pH would rise from 7.2 on my last test and two bottles of bleach (1.42/each) before bed and checked it this morning. I grabbed my cheap Walmart kit rather than my Taylor kit which I'm thinking was a bad idea. It looked like chlorine was 4ppm and I couldn't tell a differnce between free chlorine and combined chlorine and I got what looked like almost 8.0 on pH. I don't see anyway that pH came up that much from one box of borax. I should have used my Taylor kit. I'll test again when I get home in a bit to see what I get.
