Testing your pool or spa water shouldn't feel like a chemistry exam. AquaChek helped pioneer the dip-and-read test strip, giving pool owners fast, accurate answers in seconds — no drops, no messy reagents, no guesswork. AquaChek is made by Hach, a world leader in water analysis since 1933, and is backed by more than 35 years of dedicated water-testing expertise. That pedigree is why AquaChek strips are trusted by homeowners, service technicians, and pool professionals around the world. From 7-way pool strips that read pH, chlorine, alkalinity, hardness, and cyanuric acid in a single dip, to specialty strips for salt pools and spas, AquaChek makes it easy to keep your water balanced, safe, and swim-ready — so you spend less time testing and more time enjoying the water.
