If you own a backyard swimming pool, you will want to make sure your pool water remains safe for your family and friends to swim in. Pool water requires a number of chemicals to keep it clean and bacteria free. Those chemicals must maintain a delicate balance if they are to do their job correctly. Most pool owners keep a test kit on hand to check their water regularly. This article will cover what you need to test and how often you need to do it to keep your pool as clean and safe as possible.

Choosing a Pool Test Kit

A pool test kit allows you to keep track of the chemical balance in your swimming pool right at home. There are many different types of pool kits to choose from. The best will include testing for pH, chlorine, alkalinity and calcium hardness. Other tests may also need to be performed, depending on the specific water needs of your pool. Some experts recommend using tablets instead of liquid tests, because the tablets tend to provide more accurate results. Never use test kits that are expired, because they might give you an inaccurate reading. It is important to follow the specific directions of your test kit to ensure the tests are done properly.

Although many swimming pool professionals recommend testing your pool water daily, most pool owners can get away with performing a test once a week. However, if your pool is used on a daily basis, more frequent testing is necessary. The most frequent tests to perform are the pH and chlorine tests. Alkalinity, calcium hardness and other testing can be done on a weekly, or even monthly, basis. In addition, pool owners should take a sample into a swimming pool dealer every six to eight weeks for professional testing. Some dealers will offer this service to their customers at no charge, at least for a period of time after purchase.

Using the Kit

To use the kit, begin by rinsing the test cell thoroughly with pool water. Fill the cell to the indicated line and then follow the instructions for introducing the reagent. It is important to follow directions for your specific test kit carefully, since kits can vary somewhat in their processes. It is never a good idea to mix strips, liquids or tablets between kits, since this interchange can skew the test results. When tests are completed, do not return the water to your pool. When test kits are not used, they should be kept in a clean, dry place out of direct sunlight. Kits should also be replaced at the beginning of each pool season, since the kit from last season may not provide accurate results.

While testing your pool water regularly may seem like a hassle, it is imperative to keep with this schedule to ensure your pool remains safe and clean for swimming. The tests typically do not take much time to complete and the peace of mind you get in knowing your pool water is safe for your family is well worth the effort.
