Effortless, reliable water testing for pools and spas

Testing your pool or spa doesn’t have to be a chore. AquaChek Yellow 4-Way strips are designed for clean, simple, no-waste use. The flip-top bottle dispenses one strip at a time, helping you keep the rest dry and protected. Test when you need it—after a sun-drenched afternoon, before a relaxing spa soak, or during routine maintenance—and get quick results that put you in control without the guesswork.

Each strip delivers pro-grade accuracy and is trusted by pool service professionals, commercial facilities, and health departments. This reliability supports careful water balancing, so you can adjust pH, chlorine, alkalinity, or cyanuric acid with confidence, while avoiding costly mistakes.

What you’re getting

  • 50 yellow test strips that measure four key parameters: pH, free chlorine, total alkalinity, and cyanuric acid
  • Manufactured by HACH and made in the USA, reflecting decades of water analysis expertise
