As the leaves begin to fall and the air turns crisp, it’s time to start thinking about one of the most important tasks for pool owners: winterizing your above ground pool. While covering your pool and walking away might sound tempting, proper winterization does far more than just protect against chilly weather—it saves you time, money, and a lot of frustration when spring rolls around.
Why Winterizing Matters
Skipping the winterizing process can lead to all sorts of headaches. Freezing temperatures can cause expanding water to crack your pool walls, damage your liner, or even harm the plumbing. Beyond physical damage, stagnant water left untreated can become a breeding ground for algae and bacteria.
By taking a little time now, you’ll ensure that your pool stays in great condition and that reopening next season is hassle-free.
The Winterizing Process
Winterizing your above ground pool doesn’t have to be complicated. Here are the basic steps:
1. Balance your water chemistry
Adjust pH, alkalinity, and calcium hardness to recommended levels for long-term protection.
2. Shock the pool
Adding a chlorine or non-chlorine shock treatment helps eliminate contaminants before the pool goes dormant.
3. Add winter algaecide
This prevents algae growth during colder months when the water is not circulating.
4. Lower the water level
Reduce the water level slightly below the skimmer to prevent freeze damage.
5. Remove accessories
Take out ladders, toys, and any detachable equipment to protect them from weather-related wear and tear.
6. Cover it up
Use a durable winter pool cover to shield your pool from debris and harsh conditions.
Must-Have Winter Pool Products
The right pool products make winterizing straightforward and effective. Some of the most common essentials include:
Chlorine or non-chlorine shock
