The AquaChek Red 4-in-1 test strips provide a fast, easy and accurate way for testing pool water. The Aquachek test strips are the world's most commonly used test strips for pools and spas. They can be used to measure pH, bromine, alkalinity and total hardness, all in one go. After 15 seconds, you can compare the colours on the test strip with those on the packaging.
It is very important to measure these values. A correct pH value makes for pleasant swimming and ensures that other maintenance products do their work effectively. If the pH value is more than 7.6 or less than 7.2, you should add the appropriate pH product.
Bromine disinfects your pool and results in bright water, so a correct bromine value is essential.
Alkalinity and total hardness are secondary parameters; more information can be found on the packaging.
Make sure you read the packaging before using these test strips.
