Test strips for quick and easy measurement of pH, chlorine and alkalinity in water. The naked eye cannot judge the exact quality of the water, so it’s worth checking pH and chlorine levels twice a week to ensure that the water in your hot tub is in the best possible condition.

Instructions for use:

• Dip one test strip into the hot tub and compare the colours of the strip against the chart on the side of the pack.
• Add the necessary chemicals to the pool when the test result is ready.
