I never had issues with figuring out our pH using the basic OTO test kit for pH and chlorine. Well, today, I am having a major issue determining what our pH is as I have never seen this color before. Yesterday, our pH was fine and is usually somewhere around 7.6 or so, but today, it is a more red color, and I can't tell if it is darker than 7.8, or lighter than 7.8 and somewhere in between 7.5 and 7.8. Anyone run into this before? Tried taking pics to show you guys but the pics do not come out good enough as to where you can tell the exact color.
What would a reddish color indicate? I'm assuming it goes from that brownish-pinkish tone at 7.5 to a more reddish color (between 7.5 and 7.8) and then to the purplish color at 7.8 and beyond, is that correct?
