Seven steps to partially winterizing your pool

Swimming SEC 2007 Claire MaustEven if you keep it open year round, you can still take steps to winterize your pool to protect it from freezing, keep the water healthy and save money. If you close your pool in the winter, read six steps to winterizing your pool.

Here are seven steps you should take to prepare your pool for cooler months:

Clean the walls and floor: Thoroughly clean your pool, including vacuuming, brushing and scrubbing the walls and floor.

Clean the filter: Cleaning your filter will keep water moving more efficiently.

Check pH, alkalinity and calcium hardness: pH is the measure of acidity in the water, and is alkaline dependent, i.e., alkalinity keeps the pH from bouncing up and down. To maintain proper water balance, alkalinity should remain at 80-120 ppm (this may vary dependent on the water in your area, your pool finish, and other chemicals in the pool), pH should remain between 7.2 and 7.8 and hardness should be between 200 and 400 ppm. 

Check your pump run time: During colder months, you want to always run your pump during the coldest time of day for at least five hours.

Freeze protect your pool: Install freeze protection controls that have a sensor that measures air temperature and runs the pool pump when a minimum temperature is reached. If you don’t want to invest in freeze protection, set up text alerts to notify you when the temperature drops to prompt you to turn on your pool pump. Leave the pump on until the temperature rises again.

Algaecide: Use algaecide to kill any existing algae and prevent new blooms during the winter. 

Cover the pool: Use a pool cover to keep debris out and help prevent the water from freezing. This will also save you money on heating.
