When is the best time to close my backyard pool?
The main purpose in winterizing your inground swimming pool is to protect it from damage due to freezing water. Another is to keep it as clean as possible for the next season. Closing your swimming pool properly can save you a lot of work when it comes time to open the swimming pool for the summer.
You may be thinking about when is it the best time to close your pool. Every year we get asked this question so hopefully we can clarify when it will be best to close your pool.
There are a few different answers depending on your situation. The first thing is whether or not you plan on continuing to swim or not. The amount of leaves in your backyard will also help determine when it is a good time to close the pool.
DesRochers Backyard Pools and Spas recommend closing your swimming pool in late September to mid October. The reason for this is the water temperature. This is generally when the temperature drops into the low 60's and just before the leaves fall.
Water temperature is a key ingredient in the growth of algae so it is best to wait until the ambiant water temperature drops to 60 degrees or less. Once the water temperature drops to 60 degrees or below the chlorine will stay in the water helping to kill algae.
If you have any trees around your property then you will want to cover it before they start falling in the pool. If you do get any leaves in the pool you will want to vacuum them out as soon as possible. Leaves in a pool start to rot producing food for algae.
The first step in the winterization procedure is to make sure your water chemistry is balanced. You should make sure that your pH, Total Alkalinity, and Calcium Hardness are all balanced. By balancing your water chemistry for the winter you are protecting the surface of the pool from staining and etching. It is different than in season chemical balance.
Adding a winterizing chemical kit to your water will help keep it blue and clear for the next season. Be sure to follow the manufacturer's instructions for the kit.
Do not use a floater that contains a strong oxidizer (chlorine or bromine) as the floater will stick against the wall and stain and/or bleach your wall, especially a vinyl liner. For the same reasons DO NOT throw chlorine or bromine tablets into the pool. They will sink to the bottom and damage your pool's surface.
When water freezes, it expands. This can cause great damage to your pool, pool plumbing, and its filter system. If you are closing up your pool for the winter, you should always take precautions to protect from freeze damage no matter where you live. You can never be sure that it will not drop below freezing, even in the Sun Belt.
