Winter pool maintenance is crucial, even if it sees little to no use. Proper winter care allows your pool to remain in excellent condition all year round, meaning no costly repairs and making the transition to warmer weather that much easier. Below, we dive into seven key maintenance tips that will keep your pool in tip-top shape throughout winter.
1. Regular Pool Cleaning is a Must
Even in winter, it’s essential to remove debris such as leaves, twigs, and any other waste from the pool surface. If left unchecked, these materials can decompose or introduce harmful bacteria to your pool, leading to poor water quality and potential damage to your pool. Regularly cleaning the skimmer basket is also important to maintain proper filtration and water circulation. For those not using a pool cover, this task is all the more critical.
2. Maintain Balanced Pool Chemicals
Balancing pool water chemicals is a year-round responsibility. During winter, it’s vital to check the water levels and adjust the pH, alkalinity, and sanitiser levels regularly. Balanced water chemistry prevents algae growth and keeps the pool water clean, ensuring that your pool is ready for use as soon as the weather warms up. Neglecting this can lead to issues that are difficult and costly to fix later.
3. Keep the Pool Pump and Filter Running

Contrary to popular belief, your pool’s filtration system should stay running during the winter. While you can reduce the running time to save on energy, it’s essential that the water continues to circulate. Moving the water through the filter at least once a day is necessary to maintain water quality and prevent still water, which can lead to algae growth and other issues. Regular inspection and cleaning of the equipment are also recommended to make sure things continue to run smoothly.
4. Monitor and Adjust Water Levels and Chlorine
Heavy winter rains can dilute the chemicals in your pool and affect the balance in pH levels. It’s important to regularly check and adjust the water level to make sure it remains within the right range. Similarly, there is still a need for chlorine in colder weather.
Regular testing and making adjustments is much needed when keeping your swimming pool safe and healthy. Using a chlorinator set to slow release can help maintain consistent chlorine levels during this period.
5. Monitor and Treat Algae
Winter conditions, combined with reduced water circulation, can create an environment for algae to grow. But what should you look out for and how can you stop algae in its tracks?
Common Causes of Pool Algae
Winter Conditions: Cooler temperatures and seasonal changes can create a favorable environment for algae growth.
Reduced Water Circulation: When pool circulation decreases, it can lead to stagnant water, which encourages algae to flourish.
How to Spot Algae
Black-Spot Algae: Look for dark spots on the pool walls, floor, or around the waterline.
Other Forms of Algae: Watch for green, cloudy, or discolored water, which are clear indicators of algae presence.
How to Treat Algae
Increase Sanitiser Levels: Boost the sanitiser levels in your pool to kill algae and prevent further growth.
Use Algaecides: Apply algaecides specifically designed to target and eliminate algae. This will stop the algae in its tracks and prevent it from spreading.

6. Invest in a Pool Cover
A pool cover is an effective way to reduce the time and effort required to keep your pool clean during the off-season, saving you time and money. They also help retain heat, reduce the amount of debris entering the pool, and limit the growth of algae by blocking sunlight..Consider investing in a pool cover to minimise winter maintenance and protect your pool.
