Your pool water should be tested two to three times a week. Keeping track of your water balance will create an optimum swim environment for you and your guests and ensure a long life for your pool.
Roll up your sleeves and reach down to elbow length for the best water sample – around 18 inches. A usable sample should include 8 ounces of water – trapped in a sample bottle or any clean, plastic container. When conducting your own two-to-three-times weekly water analysis, remember that there are specific ranges for each test.
The most important factor to your water balance is the pH. The pH sets the tone for your water and keeps things safe and inviting to your family and friends.
Total Alkalinity, or TA, refers to the alkaline materials dissolved in the pool water. Your water’s ability to resist pH changes depends on the alkaline material. Low TA can cause the pH to “bounce” in and out of range. High TA makes it difficult to adjust the pH as needed.
Calcium Hardness denotes the amount of dissolved minerals (mostly calcium carbonate) in your water. Low Calcium Hardness can corrode equipment or cause etching in the plaster finish. High levels can lead to cloudy water or scaling.
Deliver a water sample to your pool care professional once a month, or whenever you have questions about water levels. They will analyze the water and provide you with the necessary instruction to ensure proper water balance and chlorination levels in your pool..
