Test Strips - Chlorine
Chlorine Test Strips will provide accurate testing of your hot tub water to maintain clean and clear water. Each pack contains 50 strips.
For best results make sure your spa is within the following ranges:
• Total Alkalinity (ppm) 80 to 120
• pH 7.2 – 7.8
• Calcium Hardness (ppm) 150 to 400
To keep your pool in prime condition, test at each end of your Cal Spa a minimum of twice a week and before each use.
