I'm trying to make sure I have decent readings and I got a sample in a plastic bottle with a known pH value. Like an idiot, I didn't test it when I first got it and when I did (almost three weeks later), I got a slightly lower value than I was supposed to. Would sitting in the plastic bottle too long do that?
Also, does anyone have any suggestions on where to buy waters with known concentrations (ph, cya, alkalinty, whatever) for this purpose?
