Aquachek Four In One Test Strips

For Pool & Spas that use Chlorine.  One dip and you'll test for the 4 most important factors:

• Free Chlorine (this is the form of chlorine that is free to do the work of sanitizing and oxidizing)
• pH
• Total Alkalinity
• Cyanuric Acid (Stabilizer).

Just dip an AquaChek Yellow strip in your pool or spa water for one second and remove it immediately. You get test results in seconds!

TIPS:  To keep your pool at its best, test a minimum of twice a week, and test your pool before each use.  If adjustments are needed, do so as soon as possible to avoid potential problems.

Comes with complete instructions, easy-to-read color matching and snap-seal lid. 
50 strips per bottle.
