Testing your pool 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. Leslie's recommends that you bring in your water to be tested at least every two weeks during the summer and our FREE 9-point water test gives you the most accurate water chemistry reading.

What We Test For:
If your chlorine level is too low you may get algae and bacteria growth. However, if it's too high you may get staining. Plus, you will be spending more money than necessary on chlorine.
When your pH is low it means your pool water is too acidic, which can cause burning eyes and skin irritation. Also, low pH is corrosive to your pool finish and equipment. This could lead to costly repairs or refinishing costs. pH that is too high means your pool water is too basic. This also causes skin and eye irritation, as well as causes your chlorine and bromine less effective. When this happens you can get scale build-up. Your pH should be between 7.4 and 7.6.
Your Total Alkalinity should be above 100 ppm. Low alkalinity can cause rapid deterioration of some types of pool surfaces and fittings. It can also lead to metal stains. High alkalinity can cause stains as well. It may also cause scale build-up, which can impact the efficiency of your pool equipment. High alkalinity can also prevent the pH from being balanced, which will lead to the issues detailed above.
When the calcium hardness is too low the water becomes corrosive, which may lead to staining and etching of your pool’s finish. It will also wear down and damage your equipment and metal fittings. When the calcium hardness is too high, scale starts to build up and staining can occur. This may cause your pool equipment to run inefficiently. The only way to reduce calcium hardness is by adding fresh water. Calcium hardness should be between 200 and 400 ppm.
Low stabilizer levels will cause your pool to use more chlorine than necessary, and that costs you money. High stabilizer levels can lead to stains or spot etching of your pool’s finish. Your stabilizer should be between 40 and 100 ppm.
Total Dissolved Solids (TDS)
The TDS in your pool should be below 3,000 PPM. High TDS levels make it difficult for your pool chemicals to dissolve and do their job. This can lead to persistent issues with algae, cloudiness, and staining. Also, pool water with a high TDS level can taste salty. The only way to lower TDS is to dilute the pool with fresh water.
