Each strip tests total hardness, total and free chlorine, total bromine, pH, total alkalinity and cyan acid.

Just dip an AquaChek Silver strip in your spa (hot tub) or pool for one second and remove it immediately. You get test results in seconds. It couldn't be easier! To keep your spa at its best, test the water before each use. Test your pool at least twice a week. It's also a good idea to write down your results each time you test, so you can track changes over time.

100 strips per bottle.
