Testing your pool or spa water is easily one of the most important things you can do for your pool. By obtaining an accurate reading of your water chemistry, you can understand exactly how much product to put in your pool. This not only saves you money by preventing the possibility of over-treating your water, but also keeps your pool healthy all year long. Wilkes Pools-N-Spas recommends that you bring in your water to be tested at least every two weeks during the summer and our FREE state-of-the-art computerized water test gives you the most accurate water chemistry reading available.
