Recording water balance trends will help you anticipate future changes in water chemistry, making it easier to maintain water balance over time. You can use a daily planner, dedicated pool calendar, or enter them into your favorite pool care app. Once you have your test results, keep track of them. Avoid sampling near pool returns or floating chemical dispensers.

Next, gather your water sample around elbow deep, or about 12-18″ below the surface. Test results from stagnant water may not be very accurate. Ensure that your testing supplies haven’t expired, and keep them stored in a dry area at room temperature.Ĭirculate the pool on the pump’s high setting for at least an hour before pulling a water sample for testing. It’s important to remember that certain factors will influence the accuracy of your water test. There are several types of testing supplies available on the market, all varying in price and accuracy.

You can also bring a water sample to your local pool store to gain a full picture of pool water health. But you may need to purchase a more robust kit for monthly testing. Many basic test kits will at least cover your weekly testing needs. Other readings for Calcium Hardness, Total Alkalinity, Cyanuric Acid, Metals, Phosphates, and Total Dissolved Solids, tend to move more slowly and can be tested weekly or even monthly in some cases.

PH and Free Available Chlorine levels should be tested more often, perhaps daily, until you come to a good understanding of how they fluctuate.

If you’re unfamiliar with your pool’s water balance trends, the pool is used frequently, the weather is exceptionally warm, you’re having water clarity issues, or if a storm recently rolled through your yard, you may need to test more frequently – at least 2-3 times per week. Add chemicals if you see an increase/decrease in ideal chemical levels. We recommend testing your pool water at least once per week. However, it definitely involves regularity and consistency on your part. Testing your pool water and maintaining perfect chemical harmony isn’t rocket science. Of course, there are instances when test results might fall slightly outside of these ranges, and that’s usually OK! As long as you’re actively making adjustments to water chemistry and trying to maintain water in the ideal range, you’re on the right track.


However, you should use Equation 16.45 and Equation 16.We have all heard of “testing the waters.” But when it comes to swimming pool care and maintenance, water testing is the best route to ensure you have an easy-to-maintain pool. In this and all subsequent examples, we will ignore \(\) and \(\) due to the autoionization of water when calculating the final concentration.
