AquaChek® Biguanide
Tests for Biguanide, Total Alkalinity and pH
 

 
Biguanide is a chlorine-free sanitizer such as Baquacil® Chlorine-Free Swimming Pool Sanitizer and Algistat, BaquaSpa™ Sanitizer, SoftSwim™ Bactericide, PolyClear® MaxiPolish Swimming Pool Sanitizer and Algistat, or Revacil® Swimming Pool Sanitizer.*

AquaChek™ Blue uses a two-part test. First you dip the strip and check the Total Alkalinity and pH. Then you re-dip the strip, moving it back and forth underwater for 30 seconds, to test the Biguanide level.

To keep your pool or spa water at its best, test a minimum of once a week! It’s also a good idea to write down your results each time you test.

Comes with complete instructions. 25 strips per bottle.
