Which closing kit should I get?
[open]
The best way to determine which pool closing kit to get is by reviewing the chemicals you already have. This will determine what you need. For example, if you already have enough shock, then you can get a closing kit without shock included.
If you have a saltwater pool, consider purchasing a saltwater closing kit specifically designed for use with saltwater pools.
Should I use chlorine shock or non-chlorine shock?
[open]
Over the course of the winter, chlorine can be harsh on your pool’s surface, but it effectively kills any bacteria that may linger throughout the season. Since non-chlorine shock is as effective as chlorine shock, it comes down to personal preference.
If you decide to use a non-chlorine shock, consider adding an algaecide to kill lingering bacteria further and prevent algae growth.
Do I need to balance my water before adding the winter chemicals?
[open]
Yes, you should balance your pool a day or two before you close it for the winter. Ensure that your pH, alkalinity, chlorine, and calcium hardness levels are all within acceptable ranges.

What chemicals are typically included in a pool winterizing kit?
[open]
The chemicals included in a winter closing kit will depend on which type of pool it is designed for. They will generally include a sanitizer (shock) to kill bacteria, as well as an algaecide to prevent algae growth over the winter.
