There are many good reasons to go through a formal pool cleaning process every season. Winterizing your pool correctly protects it from damage, gets the water in good condition for the months it is shut down, and will make it much easier and less expensive to re-open the following summer. Assuming you live in a climate where it is important to winterize your pool, here’s some guidelines to help you decide when to close your pool.
Cyanuric acid stabilizes free chlorine but also buffers the water which reduces the chlorine's sanitizing ability. In this article, we dive into the relationship between chlorine and cyanuric acid, and how cyanuric acid stabilizes the amount of free chlorine in your pool.

You should test your pool pH level as often as you test free chlorine – about twice per week. To raise pH use borax or soda ash (aka washing soda). To lower pH use muriatic acid.
