What are pool test strips?

Pool test strips are must-haves for measuring chemical levels in swimming pools or hot tubs. They’re thin pieces of paper or plastic with different chemicals that change color based on water conditions.

These strips let owners quickly and easily check chlorine, pH, alkalinity, and other chemical levels. Just dip them in the pool water for a few seconds and compare to a color chart. The chemicals on the strip will react differently to different levels of chlorine, pH, or alkalinity – giving an accurate reading. Some strips also have indicators for hardness, cyanuric acid, or salt.

Using these strips regularly helps maintain balanced water chemistry, prevent algae growth, and keep pools safe and enjoyable. Make sure to follow manufacturer instructions on storage and expiration dates. Keep them in a cool, dry place away from sunlight. Plus, don’t touch the reactive areas of the strip with bare hands – oil or contaminants can mess up results.
