Marimex Spa 6-in-1 test strips let you easily monitor key water values without complicated equipment. Simply dip a strip briefly into the water, remove it, and after 15 seconds compare the color to the chart on the packaging. This quickly shows whether the water in your hot tub or pool is properly treated and ready to use.
What the strips measure in a single test:
Recommended use: test at least twice a week. Dip the strip into the water and remove it immediately. Hold it horizontally for 15 seconds (do not shake off excess water), then compare the pad colors with the color chart on the label (in order: pH, free chlorine, total alkalinity, stabilizer). When not in use, always tighten the cap firmly and use before the date stated on the cap.
