Algae growth not only ruins the appearance of your pool but also creates slippery surfaces, clogs filters and makes swimming unsafe. So, you’ll definitely want to keep algae under control.

This article will share nine essential pool care tips to help you keep algae at bay and enjoy your swimming pool to the fullest.

From regular maintenance tasks to the use of algaecides, these tips will show you how to prevent algae in pool.

Tip #1: Maintaining Proper Pool Chemistry

Maintaining proper pool chemistry is key to preventing algae growth in your swimming pool. By ensuring that key factors, such as sanitizer levels, pH balance, and alkalinity, are in the right range, you’ll create a hostile environment for algae. Follow these essential tips to maintain proper pool chemistry.

Chlorine

First, check your pool’s chlorine level. Chlorine is a crucial sanitizer that eliminates algae and bacteria from your pool water. Regularly test the chlorine level using a test kit and aim for a range between 1 to 3 parts per million (ppm). Adjust the chlorine level in your pool as necessary to maintain this range.

pH level

Next, pay attention to your pool’s pH level. The pH of your pool water affects how effectively chlorine works as a sanitizer. Ideal pH levels should be between 7.4 and 7.6, which is slightly alkaline.

If the pH level is too low, your pool water becomes more acidic, potentially damaging your pool’s finish and equipment. Conversely, high pH levels make chlorine less effective, creating an inviting environment for algae. Adjust your pH level accordingly using pH increasers or decreasers.

Alkalinity

In addition to pH, proper alkalinity is essential for your pool’s overall water chemistry. Alkalinity serves as a buffer that stabilizes pH levels and helps prevent rapid fluctuations.

Your pool’s total alkalinity should be maintained between 80 and 120 ppm. You can adjust this using alkalinity increasers or decreasers.

Temperature

Temperature also plays a role in algae growth, as warmer water allows algae to thrive. Keep an eye on your pool’s water temperature, ensuring it doesn’t get too hot, especially during warm months. You may want to use a pool cover or a pool cooler to help regulate the temperature.

Cyanuric Acid

Lastly, remember to monitor your pool’s cyanuric acid level, which is a stabilizer that protects chlorine from sunlight degradation. Optimal cyanuric acid levels range from 30 to 50 ppm for traditional chlorinated pools and between 70 to 80 ppm for saltwater pools.

Tip #2: The Crucial Role of Pool Circulation

A well-maintained pool circulation system is key to preventing algae growth. Good water circulation ensures that pool chemicals are evenly distributed, helping your filtration system work more efficiently.

Your pool pump plays a vital role in maintaining pool circulation. It sucks water from the pool through the skimmer and pushes it through the filter before returning it back into the pool. A properly functioning pump ensures your pool water stays clean and healthy.

To achieve optimal water circulation, consider the following tips:

• Run your pump daily. Ensure that your pump operates for the right amount of time each day. Running it for 8-12 hours per day is generally recommended, but you might need to adjust that depending on your pool size and usage.
• Clean your pool filter regularly: Your pool filter is a critical component of your pool’s circulation system. Regularly cleaning and backwashing your filter will help it perform at its best. Check your filter’s pressure gauge and follow the manufacturer’s recommendations for proper maintenance.
• Adjust the pool jets: Point your pool jets in a specific direction to encourage better water circulation.
• Remove debris: Regularly clean your pool to prevent debris buildup, which can hinder proper water circulation.

By ensuring proper pool circulation, you’ll be one step closer to keeping algae at bay and enjoying a sparkling clean pool all season long.

Tip #3: Regular Brushing and Scrubbing: Your First Defense Against Algae

Regular brushing and scrubbing are your first defense against algae growth. Keeping your pool clean makes it harder for algae to thrive in the first place. So, let’s dive into the importance of regular brushing and how it greatly benefits your pool’s cleanliness.

Algae love to cling onto pool walls and other surfaces, which is why brushing the pool walls is essential. Once algae is removed from the pool walls etc the chlorine in the water can attack it easier.

Aim to brush your pool walls at least once a week, or more, depending on factors like heavy use or weather conditions since they can increase the likelihood of algae growth.

When brushing your pool, it’s important to use the right kind of brush for your pool surface. For example, if your pool has a smooth, vinyl surface, it’s best to use a nylon brush, as it’s gentle enough not to damage the liner. However, a wire brush might be more appropriate for removing algae stubbornly clinging to the surface if your pool has a plaster or concrete surface.

By brushing regularly, you’ll also help your pool’s circulation system effectively distribute sanitizing chemicals and ensure a more evenly balanced pool. This will promote a cleaner, healthier pool environment that is less inviting to algae growth.

Tip #4: Remove Leaves

Leaves and other organic debris left in the pool to decompose will help algae to bloom.

Make sure that you regularly use a pool net to remove leaves and other floating organic debris before they have a chance to become waterlogged and sink to the bottom of the pool.

If they do sink to the bottom then use a leaf rake/net to remove them before they decompose. A pool net that includes a think scoop that slides along the bottom of the pool, picking up leaves, such as the AnSun Pool Skimmer Net below is ideal.

Tip #5: Efficient Use of Algaecides

Algaecides can be a helpful addition to your pool care routine, helping you keep algae at bay and maintaining a clean and inviting pool environment. Although chlorine is the most effective solution for killing algae, using algaecides as a secondary sanitizer can be beneficial.

First, it is important to ensure you are using the right type of algaecide for your pool. Some algaecides contain copper, which can cause staining and oxidation in pools with high metal content. If you suspect your pool has high metal levels, opt for a copper-free algaecide to protect your pool surfaces.

When it comes to applying algaecides, consistency is key. Incorporate the use of algaecides into your weekly pool maintenance routine. This ensures that the algaecide remains at a sufficient level throughout the week, enhancing its effectiveness in keeping algae growth under control.

Remember, algaecides work best as a preventative measure rather than a cure-all solution for an existing algae problem. It’s essential not only to apply the algaecide but also to ensure your pool has balanced water chemistry. Regularly test your pool’s pH, chlorine, and other chemical levels to maintain optimal conditions that discourage algae growth.

Finally, here are a few friendly reminders when using algaecides in your pool:

• Always follow the manufacturer’s instructions regarding dosage and application.
• Be cautious about using algaecides with other pool sanitizers, as some products may not be compatible.
• Keep a close eye on your pool’s appearance and water clarity, as these can be early indicators of algae growth.

With these tips in mind, you’ll be well on your way to efficiently using algaecides and keeping your pool algae-free.
