How to Get Rid of Pool Algae

Get Ahead of Swimming Season With a Clear Pool

It’s almost that time of year again…

Time for algae to start growing in your pool!

Stop Pool Algae in its Tracks

A sparkling, inviting pool is the epitome of relaxation and enjoyment. However, nothing can ruin the experience faster than the unwelcome presence of pool algae. Not only is algae growth unsightly, but it can also pose health risks and make swimming uncomfortable. But fear not! With the right knowledge and a little effort, you can bid farewell to pool algae and reclaim your oasis. In this guide, we’ll walk you through the steps to banish algae from your pool and ensure it remains a haven of cleanliness and enjoyment for all.

Test and Balance Water:

The first step in combating pool algae is to test and balance your water. Testing your pool water regularly is crucial as it provides vital information about its chemical composition. Pay particular attention to your Free Chlorine level, as low levels can pave the way for algae growth. Aim to maintain Free Chlorine between 1 – 4 parts per million (ppm). If your levels are below this range, it’s time to take action.

Shock Treatment:

When faced with stubborn algae growth, a shock treatment can be a highly effective solution. Shocking your pool involves adding a concentrated dose of chlorine to rapidly raise the chlorine level and kill algae and other contaminants. Before performing a shock treatment, ensure your pH level is within the recommended range of 7.2 – 7.6. Follow the manufacturer’s instructions carefully, and be sure to keep swimmers out of the pool until chlorine levels return to safe levels.

Brush and Scrub:

Once you’ve addressed the chemical imbalance in your pool, it’s time to physically remove algae from the surfaces. Use a pool brush or scrubbing tool to vigorously brush the walls, floor, and steps of your pool. Pay close attention to areas with visible algae growth, such as corners, crevices, and around pool fixtures. This mechanical action helps dislodge algae from surfaces, making it easier for the chlorine to kill and remove them.

Algaecide Treatment:

In cases of severe pool algae infestation or persistent algae problems, using an algaecide can provide an extra layer of defense. Algaecides are specially formulated chemicals designed to kill and prevent algae growth. Choose an algaecide appropriate for your pool type and algae species, and always follow the manufacturer’s instructions for dosage and application. Remember that algaecides are not a substitute for proper sanitation and maintenance but can be a valuable tool in your fight against algae.

Regular Maintenance:

Prevention is always better than cure when it comes to pool algae. Establishing a consistent maintenance routine is essential for keeping algae at bay. This includes regularly testing and balancing your water chemistry, maintaining adequate sanitizer levels, and keeping your pool clean through routine skimming and vacuuming. Additionally, consider using a quality pool cover when the pool is not in use to prevent debris buildup and minimize algae growth.

Pro Tip!

It’s essential to prioritize regular cleaning of your pool filters as they can serve as a significant source of contamination. A clogged or dirty filter is unable to perform its intended function efficiently, impeding the water’s ability to filter through and circulate effectively. Therefore, maintaining clean filters is crucial for optimal filtration and water clarity in your pool. Cleaning your pool filter is easy, and you can see the difference in the before and after photos below. 

We Understand Your Frustration!

Dealing with pool algae can be a frustrating challenge, but armed with the right knowledge and proactive approach, you can keep it under control and enjoy a pristine swimming environment all season long. By regularly testing and balancing your water chemistry, employing shock treatments and algaecides as needed, and maintaining a diligent maintenance routine, you can say goodbye to pool algae and hello to crystal-clear waters. Now that you know how to clear up your pool water and get rid of pool algae, let’s now delve into the most effective methods for preventing its occurrence or recurrence altogether!

Prevent Pool Algae Before it Begins

Understanding the conditions that promote algae growth is key to effectively preventing its proliferation in your pool. Algae thrive in environments where the temperature fluctuates, especially during the transitional periods when the weather is warming up. Here’s an expansion on how temperature variations and salt cell functionality can impact algae growth, along with steps to prevent it:

Temperature Fluctuations

• Algae are opportunistic organisms that flourish in environments where conditions are favorable. In the spring and fall, when temperatures fluctuate between cool nights and warmer days, pools become particularly vulnerable to algae growth. During the daytime, the sun’s warmth can raise the water temperature, creating an ideal breeding ground for algae. However, when the temperature drops at night, algae can still thrive, albeit at a slower pace. This fluctuation in temperature provides the perfect environment for algae to take hold and multiply.

Salt Cell Activation

• In saltwater pools, the salt cell plays a crucial role in maintaining water clarity and preventing algae growth. The salt cell generates chlorine through electrolysis, which helps sanitize the water and inhibit algae growth. However, salt cells are temperature-sensitive and may not produce sufficient chlorine when the water temperature is below a certain threshold, typically around 57 degrees Fahrenheit (14 degrees Celsius). This means that during colder periods, when the water temperature is still below this threshold, the salt cell may not be able to produce enough chlorine to keep algae at bay.

To prevent the growth of algae during these transitional periods, here are a few steps to follow:

Monitor Water Temperature

Keep track of your pool’s water temperature, especially during the spring and fall when temperature fluctuations are most pronounced. Use a reliable thermometer to gauge the water temperature regularly. Once the temperature begins to rise consistently above 57 degrees Fahrenheit, you can expect the salt cell to start producing sufficient chlorine to combat algae growth effectively.

Supplemental Chlorination

In colder temperatures when the salt cell may not be operating optimally, consider supplementing your pool’s chlorine levels with a liquid or granular chlorine product. This ensures that there’s enough chlorine in the water to prevent algae from taking hold. Be sure to follow the manufacturer’s instructions for proper dosage and application.

Increase Circulation and Filtration

Improve water circulation and filtration to help prevent algae growth. Run your pool pump and filtration system for longer periods, especially during times of temperature fluctuation. This helps to keep the water moving and removes debris and organic matter that algae feed on, reducing the likelihood of algae taking hold.

Ongoing Maintenance

Maintain a consistent pool maintenance routine throughout the year, paying extra attention during transitional seasons. As mentioned above in the “How to get rid of pool algae” section, you want to frequently test and balance your water chemistry, skim the surface for debris, brush the walls and floor to prevent algae buildup, and vacuum the pool to remove any sediment or algae spores that may be present.

By staying vigilant and taking proactive measures to address temperature fluctuations and ensure adequate chlorine levels, you can effectively prevent algae growth and enjoy a clear, algae-free pool all year round.
