Pool Water Test Strips - 6-way Test Strips

These HTH six-way water test strips check your pool for levels of six chemical factors including free available chlorine, total chlorine, cyanuric acid, bromine, alkalinity and total hardness of the water. The pool test strips are designed to keep your pool water safe and chemically-balanced, protecting against the formation of bacteria and algae and preventing over-chlorination that can lead to skin irritation.
