Setting the Stage for Next Pool Season

As temperatures begin to drop, pool season comes to an end in many parts of the country. There are two ways to look at closing time. We can mourn the end of summer or we can look at it as an opportunity to prepare for next pool season.  Taking the time to properly close your pool will help to ensure a smooth opening next season.

Our next few posts will focus on how to properly close your pool. Don’t be sad; next pool season will be here before we know it. Preparation starts with chemistry.


This protects the pool from corrosion or scale buildup. Using a water test kit, adjust the water to the recommended levels of pH, total alkalinity, calcium (hardness) and chlorination.

If you want to add a winterization chemical kit, do it now. These kits put high levels of chlorine and algaecide in the water to prepare it for the winter months ahead. Your pool retailer offers ready-made kits for this purpose; use according to the maker's directions. In the case of larger pools, you may be directed to supplement the kit with additional quantities of some chemicals, too.


Don't add tablets or a floater that contains chlorine or bromine—these can damage the equipment nearest them. If you already have chlorine or bromine tablets in your feeder, let them run out so that none remain. If you're adding winterizing chemicals, pour them into a bucket and then into the pool. Some of these chemicals instruct you to turn on the pool filter while you add the chemicals. Make sure you do, especially if you have a vinyl liner pool—you don't want stains on your liner from un-dissolved granules or damage to your equipment from concentrations of chemicals in the water.
