AquaChek's 7 Way Test Strips give pool owners an easy, effective way to test the most important factors of system health and safety: total hardness, total chlorine, total bromine, free chlorine, pH level, total alkalinity, and cyanuric acid. Once inserted into water, 7 Way Test Strips produce a quick, accurate reading of these critical levels, helping you to identify and then correct problems in your pool.
- Dip a strip into water and remove immediately.
- Hold strip level for 15 seconds (do not shake excess water from strip).
- Compare Total Hardness, Total Chlorine, Total Bromine, Free Chlorine, pH, Total Alkalinity and Cyanuric Acid pads (in that order) to the color chart on label.
For best results on Cyanuric Acid test, pH should be between 7.0 - 8.4 and Total Alkalinity should be at or below 240 ppm.

Easy to use
Quicker to use than chemical test kits and easy to use. Hach makes great products. I use them at work for chlorinating water mains.
