Pool Water Testing

Testing your pool water regularly is essential to maintaining a balanced swimming pool or spa, helping ensure the water is healthy and clear. At Leslie’s, we offer the best pool water testing products including water test kits, water test stips, and digital water testers. These methods of water testing allow you to monitor the most important aspects of your pool or spa water chemistry. We have water testing kits and test strips that provide tests for Total Available Chlorine, Free Available Chlorine, Bromine, pH, Total Alkalinity, Cyanuric Acid, Calcium Hardness, Salt and more! Pool water testing is one of the most important steps to keep your water clean and safe for swimmers.

Pool Test Kits

Pool Test Kits are some of the most commonly used methods for testing pool water. Pool water test kits include a comparator water testing block with water test reagents along with easy to follow usage instructions. Pool test kits provide highly accurate results for many different aspects of your pool water chemistry. There are basic water test kits which test only for chlorine and pH as well as comprehensive water test kits testing for alkalinity, total and free chlorine, cyanuric acid, pH, and calcium hardness.

Pool Test Strips

Pool Test Strips are a quick and easy way to test multiple water chemistry levels in pool and spa water at once. Dip the test strip into the water, and then compare the different test pads on the test strip to the color chart on the label of the water test strip bottle. You can then see what the chlorine, pH, total alkalinity, calcium hardness, and other levels are in your pool or spa in a flash!

Digital Pool Water Testers

Digital Pool Water Testers help make testing pool and spa water even easier, without having to do any color comparison guesswork. Digital water testers allow you to get accurate water test results quickly and some digital testers even have the ability to save the history of prior water test results to keep track of water chemistry level changes.

Pool Test Kit Reagents

Pool Test Kit Reagents are an essential component for many water testing kits. Leslie’s offers replacement reagents and refills to help measure water chemistry levels such as total and free chlorine or pH. Orthotolidine, OTO pool test kits require orthotolidine dropper bottles (OTO) to test for total available chlorine. Diethyl-p-phenylenediamine, DPD pool test kits need reagent replacements including DPD powder or FAS-DPD liquid reagents which help test for free available chlorine.
