how to check for phosphates in pool water
We most often think of phosphates as what is used to give our laundry detergent its sudsiness. Phosphates are in cleaning supplies, fertilizers, some beverages, and even in some pool chemicals. You can't see, smell or taste phosphates in your pool water, but it can be tested for, with a Phosphate test kit. Phosphates commonly enter pools through wind blown fertilizer. If you have a lawn care service treating your beautiful yard, or if you fertilize azaleas surrounding the pool, it can be difficult to keep fertilizer from reaching the pool, via wind or water.
