Aquachek Red 4-in-1 Bromine Test Strip tests for 4 important chemicals in seconds: Total Bromine, pH, Total Alkalinity and Total Hardness. Our bromine strips include a test for total hardness since warmer water temperatures increase the potential for scale build-up making it particularly important for spa owners to maintain proper hardness levels.
