Pool Chemistry 101: Testing Swimming Pool Water


Water Testing and Analysis

From SwimmingPool.com

Most inground swimming pool owners have been told by their swimming pool professional that they need to test their pool water on a regular basis.  The fact is, most swimming pool owners don’t bother to test their pool water.  Whether the thought of doing a test is intimidating to them, or they simply don’t know the procedure or the expected results, the water test is the most neglected aspect of swimming pool ownership.  This post from SwimmingPool.com shows that not only is a water test simple, the results can go a long way towards extending the life of the swimming pool, thus making the return on this significant investment much greater.  There is even a handy Saturation Index calculator included in the post, which can be bookmarked for future reference.

Here is an excerpt from the post:

Test the water in your pool two to three times a week to ensure an optimum swim environment and a long life for your pool. For the best sample of water, collect from the deep end of the pool – collecting at least eight ounces of water. You can collect the water in a sample bottle or any clean, plastic container.

Langelier Saturation Index (LSI) Calculator (Scale vs. Corrosion)

The Langelier Saturation Index (LSI) is a way to evaluate your water quality data to determine if your pool or hot tub water has a tendency to form a chemical scale. You need to measure pH, conductivity, total dissolved solids, alkalinity and total hardness to use this index.
