JED Pool Tools Water Testing Strips - 50 pc.

This test strip pack is great for home pools and spas. Each strip tests for chlorine, bromine, pH, total alkalinity and hardness (the complete 7-way test also includes both free and total chlorine tests, as well as a cyanuric acid test). Easy to use and more convenient than liquid tests, just swipe and read. This 50 pack will last you all summer long and beyond, and come in a air/water-tight plastic tube to seal out moisture and dirt.
