  • Easy to read
Style: Pool Spa Water Treatment
I've been using HTH testing strips for my hot tub maintenance, and they've been an absolute game-changer. Not only are they incredibly easy to use, but the results are also very easy to read, making it a breeze to keep my hot tubs chemistry in check. I've tried other testing methods in the past, but none have offered the simplicity and accuracy that these strips provide. Whether you're a seasoned owner or new to maintenance, these strips take the guesswork out of balancing your water. The clear, color-coded results help me make quick adjustments, ensuring my hot tub is always safe and ready for a swim. For their price and reliability, I couldn't ask for a better product. ... show more
