AquaChek Yellow Free Chlorine Test Strips | 511242A

Directions:
1. Dip a strip into water and remove immediately.

2. Hold strip level for 15 seconds (do not shake excess water
from strip.)

3. Compare pH, Free Chlorine, Total Alkalinity and Stabilizer pads (in that order) to color chart on label. For best results on Stabilizer (Cyanuric Acid) test, pH should be between 7.0-8.4 and Total Alkalinity should be at or below 240 ppm. Important: Keep cap closed tight between uses. Store at room temperature. Use by expiration date on cap.

Just dip an AquaChek Yellow strip in your pool or spa water for one second, and remove it immediately. You get test results in seconds! To keep your pool at its best, test at each end at least twice a week, and test your spa before each use. It’s also a good idea to write down your results each time you test, so you can track changes.
