HACH AquaChek 7 Test Strips (100 Count) | 7-in-1 Pool & Spa Water Test
Quick, Accurate Testing for Crystal-Clear Water
Maintaining balanced pool or spa water starts with accurate testing. Without the right readings, it’s impossible to know how much sanitizer, pH adjuster, or water balancer to add. The HACH AquaChek 7 Test Strips (100 Count) make water care simple with 7-in-1 testing in just 15 seconds.
Trusted by homeowners and pool professionals alike, AquaChek 7 test strips deliver fast, reliable results for the seven most important water chemistry factors. With 100 strips per bottle, you’ll have a season-long supply of easy testing at your fingertips.
Why Water Testing Matters
Unbalanced water chemistry leads to problems that cost time, money, and enjoyment:
-
Low chlorine → algae growth, cloudy water, unsafe swimming conditions
-
High or low pH → corrosion, scale buildup, and swimmer irritation
-
High hardness → scaling and cloudy water
-
Low alkalinity → pH bounce and unstable water balance
-
Excessive stabilizer (CYA) → chlorine lock, reduced sanitizer effectiveness
By testing regularly, you can make precise adjustments and avoid expensive water issues. AquaChek 7 strips give you the information you need—fast.
What AquaChek 7 Test Strips Measure
Each strip provides results for the seven most important pool and spa parameters:
-
Total Chlorine – Ensures enough sanitizer to kill bacteria.
-
Free Chlorine – Measures the active sanitizer in the water.
-
pH – Keeps water comfortable and prevents corrosion or scale.
-
Total Alkalinity – Buffers pH to maintain stability.
-
Total Hardness – Monitors calcium levels to prevent scaling or etching.
-
Cyanuric Acid (Stabilizer) – Protects chlorine from sunlight degradation.
-
Total Bromine – For spas or pools using bromine sanitizer instead of chlorine.
With one simple dip, you get a complete snapshot of your water chemistry.
