AquaChek Biguanide test strips simplify water testing for pools and spas using biguanide instead of chlorine as a sanitizer. These water test strips measure:

  • Biguanide
  • Total Alkalinity
  • pH

AquaChek Biguanide 3 Way strips use a two-part test to check your pool chemical levels. First, dip the strip to check the Total Alkalinity and pH. Then, re-dip the strip, moving it back and forth underwater for 30 seconds, to test the Biguanide level.

These water test strips come in AquaChek's easy-grip bottle. The ergonomically-designed bottle features a flip-top cap closure. The strip dispenser efficiently dispenses just one strip at a time.
