Hot tub testing kits and strips can help hot tub and spa owners check chlorine, bromine, or pH levels. Spas should be regularly tested to ensure the water is safe and clean. If you do not test your hot tub and spa water on a regular basis, you run the risk of contaminated water which can be unhealthy for users.
Hot tub testing kits come with testing equipment and charts for analysis. Most require you to take a sample of water from your spa or hot tub, place a specified number of drops in the water sample and then analyze the color of the treated water. There is no room for error with these kits and the person testing the water must ensure that all steps are properly followed so that the results aren't skewed. Follow each step carefully in order to ensure accurate test results.
Testing strips are small sticks that you dip into the water. Spa testing strips often come in bottles with either paper charts or information on the bottle for you to match the test stick with the corresponding color in order to analyze the test results. They are offered in three-in-one, four-in-one or six-in-one variations. For example, a four-in-one or four-way strip will measure four things. Strips are disposable and are praised for being convenient and easy to use, but less precise than kits.
Hard water testing kits measure the amount of calcium and magnesium in your hot tub or spa. Usually about three-quarters of the total hardness of your spa or hot tub is calcium. Too much calcium in the water is undesirable.
Copper testing strips and kits are important for use with ionizers and they can also be used if rust on piping or equipment is suspected. Iron test strips, Total Dissolved Solids (TDS) Test Strips and Total Hardness strips are also available for their specific purpose.
Hot tub spas should be checked regularly to ensure chemical and natural pH levels are correct. Testing kits and strips are ideal for this, although some prefer to take a sample periodically to their hot tub specialist for in depth analysis. Regardless of the method you choose, it is important to test your hot tub and spa water on a regular basis to ensure it is healthy for you and your guests to enjoy.
