If the salt levels are too low, add salt accordingly. If it’s too high, wait for your levels to go down and refrain from adding any more salt or chemicals until it’s right at the ideal level.

You should also watch out for your pool water’s pH, calcium hardness, and total alkalinity levels.

pH level must be between 7.2 and 7.8 for saltwater pools, total alkalinity should be between 80 and 120 ppm, and calcium hardness at 200 to 400 ppm.

Make sure that you drain all the water from your pool equipment. You can leave a mixture of water and a non-toxic antifreeze if you can’t drain everything.

You should also winterize your skimmer by attaching a winterizing skimmer plate and a plug into the skimmer’s return fitting.

5. Cover your pool

Depending on how large your saltwater pool is, you should be using one or two air pillows on your pool before closing it for good.

Air pillows help support the cover and prevent it from sinking into your pool. They help protect your pool liner as wells as keep large ice sheets from forming on the sides of your pool.

Once you’ve put in your air pillows, it’s time to cover your saltwater pool that perfectly fits your pool. Make sure that you keep an eye on your pool cover from the day you put it on until the winter season ends. You should clear off any ice or snow that forms on top of your pool cover.

Secure your pool cover with water bags to prevent it from getting displaced by wind or weather. You can use cable and winch to secure them in their place.
