Our 7-in-1 swimming pool test strips enable quick all-around water testing to maintain safe, balanced pool and spa water. Each strip simultaneously detects seven key indicators: total chlorine, free chlorine, pH, total alkalinity, cyanuric acid, hardness and bromine, covering all essential parameters for pool care. Simply submerge the strip in pool water for one second, shake off excess liquid, and compare color blocks with the printed chart to get clear readings in under 60 seconds.

Made of high-absorbent filter paper with stable reactive coating, these strips deliver vivid, non-fading color changes for precise judgment. Compact sealed container locks out moisture to extend shelf life and avoid invalid tests. Ideal for above-ground pools, inground pools, hot tubs and spas. Far cheaper and simpler than liquid test kits, no extra reagents or complicated tools required. Perfect for home pool owners, pool maintenance workers and spa operators. Every batch passes strict quality checks to provide reliable results and help you adjust chemicals properly, preventing cloudy water, skin irritation and equipment corrosion.
