Insta-TEST Biguanide, Alkalinity, pH, Total Hardness Test Strips

Insta-Test Big/Alk/pH/Th Test Strips

Insta-Test Biguanide, Alkalinity, pH, and Total Hardness Test Strips are essential for maintaining biguanide-based pool and spa systems like Aquaspa. These easy-to-use strips deliver quick, accurate results with a clear colour chart—simply dip, shake, and read within 10 seconds. Each strip tests four critical parameters: Biguanide (0–80ppm), Alkalinity (0–240ppm), pH (6.2–9.0), and Total Hardness (0–800ppm). The protective desiccant-lined bottle keeps strips dry and effective, shielded from moisture and UV damage. Testing is straightforward: immerse to elbow depth for 2 seconds, remove with pads facing up, shake gently, wait 10 seconds, and compare to the colour chart from top to bottom. For spas, turn off jets before testing. Store strips indoors away from heat and sunlight. Test twice weekly for optimal water balance. Open the cap by pushing the tab upward with your thumb, and close firmly until it snaps. Avoid wet fingers inside the bottle. Bottle contains 25 test strips.
