In Arizona, where the weather remains relatively warm even during fall and winter, it’s important to take extra care in cleaning your pool to ensure it remains in good condition. In this blog post, we will discuss some best practices and share a few tips on effectively cleaning your pool during the fall and preparing it for winter.

1. Removing Algae:

The first step in fall pool cleaning is to tackle any algae growth that may have occurred during the summer months. Algae thrives in warm weather and can quickly spread if left untreated. To remove algae, start by using an algaecide to kill off any existing growth. It’s important to choose an algaecide specifically formulated for your pool type and follow the instructions carefully. Once the algaecide has done its job, use a pool brush to scrub the walls and floor of your pool to remove any remaining residue. Finally, shock your pool to destroy any remaining algae and restore crystal clear water.

2. Skimming and Brushing:

With the leaves falling from nearby trees during the fall season, it’s crucial to keep up with regular skimming and brushing to prevent debris buildup in your pool. Skim the surface of the water daily to remove leaves, insects, and any other floating debris. Use a pool brush to scrub the walls and floor, paying special attention to corners and crevices where dirt and algae can accumulate. Regular skimming and brushing will help maintain clean water and reduce the need for chemical treatments.

3. Check and Maintain Water Chemistry:

During fall, it is essential to regularly test your pool’s water chemistry and make necessary adjustments to ensure a safe and comfortable swimming environment. The warm weather in Arizona can cause increased evaporation, which can lead to imbalances in pH, alkalinity, and chlorine levels. Test your pool water at least once a week and adjust the chemical levels as required. Maintaining proper water chemistry will not only keep your pool water sparkling clean but also prevent any potential damage to the pool equipment.

4. Check and Clean Pool Filters:

Your pool’s filtration system plays a crucial role in removing impurities from the water. During fall, when debris is more likely to accumulate in your pool, it’s important to regularly check and clean your pool filters. Remove the filter cartridges and give them a thorough rinse to remove any trapped dirt or debris. If you have a sand or diatomaceous earth filter, perform a backwash to flush out any accumulated debris. Regular filter maintenance will ensure optimal filtration and help keep your pool clear and inviting.

5. Prepare for Winter:

While winters in Arizona are relatively mild, it’s still important to take some steps to prepare your pool for the colder months. Start by lowering the water level in your pool to prevent potential damage from freezing temperatures. Consult your pool manufacturer’s guidelines to determine the appropriate water level for winter. Additionally, consider using a pool cover to keep debris out and retain heat in mild winter days. Finally, ensure your pool equipment is properly winterized to prevent any freeze damage.


Cleaning your pool during fall in Arizona requires special attention to detail to ensure your pool remains clean and inviting throughout the year. By removing algae, regularly skimming and brushing, maintaining proper water chemistry, checking and cleaning pool filters, and preparing for winter, you can enjoy your pool in all seasons while minimizing the risk of any damage or maintenance issues. So, roll up your sleeves, follow these best practices, and get ready to enjoy a beautiful fall and winter season in your sparkling clean pool.
