A pool water tester is a device that measures the chemical levels of your pool water, such as chlorine, pH, alkalinity, and hardness. Testing your pool water regularly is important to maintain a safe and comfortable swimming environment. There are different types of pool water testers, such as liquid kits, test strips, and digital meters
. Here are some general steps on how to use a pool water tester:
Choose a pool water tester that suits your needs and budget. Liquid kits are more accurate but require more time and skill. Test strips are easy and quick but less precise. Digital meters are convenient and reliable but more expensive.
Collect a water sample from your pool. The best way to do this is to hold a clean container upside down and submerge it about 18 inches below the surface. Then, turn it right side up and bring it out of the water.
Follow the instructions of your pool water tester. Depending on the type, you may need to add drops of reagents, dip a strip, or insert a probe into the water sample. Wait for the color change or the reading to appear.
Compare the results with the ideal ranges for your pool water. The ideal ranges may vary depending on the type of pool and the sanitizer you use, but generally they are:
Free chlorine: 1 to 3 parts per million (ppm)
pH: 7.2 to 7.8
Total alkalinity: 80 to 120 ppm
Calcium hardness: 200 to 400 ppm
Cyanuric acid: 30 to 50 ppm for chlorine pools, 70 to 80 ppm for saltwater pools
Adjust your pool chemicals accordingly. If your pool water is out of balance, you may need to add or reduce certain chemicals, such as chlorine, acid, base, or stabilizer. Follow the manufacturer’s directions and use a pool calculator to determine the correct dosage
