AquaChek Spa is a six-in-one test strip developed specifically for hot tubs. The 15-second, dip-and-read strip includes tests for six parameters: total chlorine, total bromine, free chlorine, total alkalinity, pH and total hardness. To use, dip the test strip into the spa or hot tub, compare using the color chart and adjust chemical levels as needed.
