Hth Pool Care 6-way Test Strips (30-count)

6-way test strips. Test for free available chlorine, bromine, pH, alkalinity, calcium hardness, and CYA (cyanuric acid) levels. If left untreated, unbalanced swimming pool water can irritate swimmers skin and eyes, cause sanitizers to work less effectively, and even damage pool surfaces, structures or equipment. The good news is that you do not need to be a scientist to quickly and easily test your indoor and outdoor swimming pool water. These test strips are great for all swimming pool types including chlorine, bromine, and salt water systems.
