Accuracy of the readings
The PH on the strips come out bright pink (high PH) --no matter what chemicals I put
into the hot tub. Therefore, I don't fully trust what the PH is. The rest of the readings
on the strips seem OK. Actually, the pink always comes out smeared a little (unlike the
other colors that stay in the box.)
Does this mean the PH is thinking "outside of the box?"
