Getting into untested water is a gamble — one that's over in 15 seconds if you skip it. Test your hot tub water in seconds with ClearWater® 4-in-1 Dip Test Strips, made by the original pioneers of dip testing and trusted for the most accurate at-home readings on the market. This 150-pack means you're covered for a full season of regular testing without running out partway through.
Each strip reads chlorine, bromine, pH and total alkalinity in one dip, with results ready in just 15 seconds and a simple colour-match scale that takes the guesswork out of interpreting them. Untested water can quickly become unbalanced, leading to bacteria growth, cloudy water, and even damage to your hot tub over time — regular testing with ClearWater strips keeps your spa safe, clear and comfortable every time you use it. These strips are also available in smaller 25 and 50 strip packs, but the 150-pack is the practical choice if you're testing regularly through the season.
Ideal for hot tub owners testing before every use, and perfect for anyone who wants a season's supply of test strips without reordering constantly, this pack keeps you a dip and 15 seconds away from knowing your water is ready.
