I've come to the conclusion that I'm having a hard time reading "red". Can't figure out my pH reading for the life of me. I have to ask about 4 people before I write down my pH results, so I think it's time to go with a pH meter here. Has anyone used this before? If so, how does it work for you? I can calibrate it..no problem. I just need to find a way to test for pH without the hassle of trying to read "red". My eyes can't make out colors the way they used to.
