Includes OTO, Phenol Red, and a water sample tube for accurate testing of pH and chlorine or bromine. Generally there are two types of test kits for swimming pools: liquid test kits and test strips. Some pool owners prefer test strips, since they provide information on factors such as calcium hardness, total alkalinity and stabilizer. Liquid test kits for pools such as this one are often preferred due to their simplicity and accuracy. Because they test the two most components of pool water (pH and Chlorine), liquid test kits give you the information you need to keep your pool balanced.
