These strips work well for testing my spa/hot tub chemical levels. I only wish the print was larger on the bottle. I need to use a magnifying glass in order to read the label.

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?"

This does it all for the new spa owner. what most others lack is testing calcium hardness which is essential to managing good water in a spa....so different than managing a pool! Thanks for this super "aide"!
