AquaChek Test Strips are the fastest and easiest way to test your spa or hot tub. You should test at least 2 times per week and after each use. Takes 15 seconds for the most accurate results. Tests for total chlorine, total bromine, free chlorine, total alkalinity, pH and total hardness. Knowing your total chlorine level will help you determine when you need to shock the water. An ideal level of bromine ensures clean, clear water that is safe for bathers. A correct level of total alkalinity prevents sudden pH changes. Maintaining a proper pH level helps prevent scale formation and corrosion, which can lead to costly repairs. Monitor your hardness levels to protect against corrosion, scale formation, cloudy water, or excess foam. Includes 50 test strips.
