Pool Care During Winter
Proper pool care during the winter is essential to reduce cost of chemicals and labor when it is time to open up back in the spring. Even if the pool is not covered during the cold season, proper chemical balance and clearing of debris is needing to prevent staining and other problems. For an in-depth analysis of how to keep your swimming pool well maintained during the winter months, free and comprehensive computerized water sampling is offered in store at 2300 Holcomb Bridge Rd, Roswell GA, 30076.


Less chlorine is required to keep pool water clean during the winter months due to the temperature of the water being lower. Chlorine tablets will dissolve more slowly than during the warm season, but it is advised to make sure the pool is within a 1ppm - 6ppm free chlorine range during the winter months to keep the water free from organic material and bacteria. This will also highly lessen the risk of having an algae bloom as the temperatures start to rise in the spring.


Maintain a pH level in the range of 7.2 - 7.8. High pH promotes scaling on the surface, while a low pH promotes corrosion of the surface.


Maintain a normalized level of 80ppm-120ppm to correctly buffer the pH (keep it from fluctuating).

Calcium Hardness

Maintain a normalized level of 200ppm - 400ppm to ensure long life of pool surface finish. When Hardness level is too low, the water will etch and corrode the pool surface finish to equalize its calcium need. 


Since the UV from the winter sun is not as strong as the summer sun, it is acceptable to run the pool with low levels of stabalizer. It is recommended, though, to still maintain at least 30ppm of stabalizer in the pool water.

Salt Water Chlorine Generation

When pool water is 55 degrees Fahrenheit or below, your salt system will mostly likely shut itself off, as no chlorine will be produced at or below this temperature. To keep chlorine levels consistent, putting a chlorine tablet or two in a floater or in the skimmer will be sufficient to maintain chlorine levels while the salt system is inactive.

Algae Prevention

Algae growth is severely slowed in water with cold temperatures, so with proper maintenance of a 1ppm - 6ppm chlorine level, the risk of algae bloom during the winter months is low. If algae does appear, a dose of shock or algaecide based on water volume and intensity of algae bloom is recommended to kill the algae.

Pool Cleaner

Running your pool cleaner one to two hours a day is recommended to keep the pool looking its best, even during the winter. If pool has a large amount of leaves, it is recommended to also manually empty pool of leaves with a net alongside use of a pool cleaner, as a heavy amount of leaves and debris will jam up and break pool cleaners.
