How to Remove Algae from a Saltwater Pool

If you own a saltwater pool, you may have encountered the frustrating problem of algae growth. Algae can turn your pool water green, making it unsightly and unpleasant to swim in. Fortunately, removing algae from a saltwater pool is possible with the right steps and maintenance. In this article, we will guide you on how to effectively remove algae from your saltwater pool and keep it from coming back. From understanding the different types of algae to balancing water chemistry and using shock treatments, we've got you covered.

Understanding Algae in Saltwater Pools

Before we dive into the process of removing algae, let's first understand the types of algae that can invade your saltwater pool and the difference between saltwater pools and chlorine pools.

Types of Algae

Algae comes in different forms, including green algae, yellow (mustard) algae, and black algae. Green algae is the most common and easiest to remove, while yellow and black algae require a bit more effort. Each type of algae may require a specific approach for effective removal.

Saltwater Pools vs Chlorine Pools

Contrary to popular belief, saltwater pools are not chlorine-free. They use a device called a saltwater chlorinator to convert salt into chlorine through a process called electrolysis. The advantage of saltwater pools is that they produce chlorine at a slow and steady rate, which is gentler on the skin, hair, and eyes. However, this consistent chlorine production can make saltwater pools more susceptible to algae growth if the water is not properly balanced.

Removing Algae from a Saltwater Pool

Now that we have a basic understanding of algae and saltwater pools, let's move on to the practical steps of removing algae from your pool.

Brushing the Pool Surfaces

The first step in removing algae is to brush all the pool surfaces. A regular pool brush may not be effective against algae, so it is recommended to use an algae brush with stainless steel bristles. For vinyl liner pools, a nylon-bristled brush can be used, but more effort may be required. Brushing not only helps remove algae but also prevents it from sticking to the walls and floor of your pool.

Vacuuming the Algae

After brushing the pool surfaces, it's time to vacuum up the loosened algae. Make sure to vacuum the algae away from the pool to prevent it from reintroducing into the water. You may need to add some water to your pool afterward to bring it back to the ideal level.

Testing and Balancing the Pool Water

Once you have removed the visible algae, it's crucial to test and balance your pool water for pH and alkalinity. The optimal pH range is between 7.4 and 7.6, while the alkalinity should be maintained between 100 and 150 parts per million (ppm), with 125 ppm being ideal. Balancing the water chemistry is essential to ensure that your pool remains algae-free.

Shocking the Pool

To effectively kill any remaining algae and prevent its resurgence, shocking the pool is necessary. Since saltwater pools are essentially chlorine pools, you will need to use chlorine shock for this process. The amount of shock you need depends on the severity of the algae infestation.

• For a green-colored pool, double the usual amount of shock.
• For dark green or a lot of algae, triple the usual amount.
• For yellow (mustard) algae, triple the shock amount as it can be chlorine resistant.
• For black algae, quadruple the shock amount as it is even harder to kill.
• If the pool appears black due to extreme algae growth, triple or quadruple shock may be required.

It's important to follow the guidelines for shock treatment specific to your pool volume. Once shocked, ensure that the filter system runs for at least eight hours to allow the shock to work effectively. It's recommended to shock the pool at night when nobody is using it and to regularly test the water to ensure chlorine levels have returned to normal.

Dealing with Different Types of Algae

Different types of algae may require slightly different approaches for effective removal. Here are some specific tips for dealing with green algae, yellow (mustard) algae, and black algae:

Green Algae

Green algae is the most common and easiest to remove. By following the steps mentioned above, including brushing, vacuuming, balancing water chemistry, and shock treatment, you can effectively eliminate green algae from your saltwater pool.

Yellow (Mustard) Algae

Yellow or mustard algae can be more persistent and chlorine resistant. In addition to the regular removal steps, it's important to triple the shock treatment for mustard algae. Keeping the pool's chlorine level between one and three parts per million (ppm) is crucial to prevent the recurrence of this type of algae.

Black Algae

Black algae is the toughest type to eliminate as it embeds itself into pool surfaces. To kill black algae, quadruple the amount of shock and ensure thorough brushing. It may require multiple treatments to completely eradicate black algae from your pool.

Maintaining an Algae-Free Pool

After putting in the effort to remove algae from your saltwater pool, it's important to take preventive measures to keep your pool algae-free. Here are some tips to maintain a clean and clear pool:

Balance Water Chemistry

Regularly balance the water chemistry of your pool at least once a week or more frequently if you have heavy pool usage. Ensure the chlorine level stays between one and three parts per million (ppm), ideally reaching three ppm. Balanced water chemistry helps prevent algae growth.

Showering Before Swimming

Encourage pool users to shower before getting into the pool. A quick rinse helps remove any organic substances, such as sweat or oils, that can contribute to algae growth.

Cleaning Swimwear and Equipment

If you have been in a natural body of water or a public pool, wash your swimsuits. A rinse is sufficient for regular pool usage. Additionally, clean pool toys and other equipment with diluted bleach or a bleach-based cleaner to kill algae and prevent mildew. Rinse thoroughly to remove any residue before placing them back in the pool.

Using Boost Mode on Saltwater Generator

Some saltwater generators have a "boost mode" that releases an extra dose of chlorine. Use this feature weekly or more if necessary, keeping in mind to activate it at night when the pool is not in use to allow chlorine to dissipate.

Regularly Balancing Water Chemistry

Similar to the previous point, it is essential to consistently balance the water chemistry of your pool. Maintaining chlorine levels at three parts per million (ppm) helps prevent algae growth and keeps your pool water clear and safe for swimming.

By following these preventative measures and regularly maintaining your saltwater pool, you can enjoy a clean and algae-free swimming experience.

Conclusion

Algae growth in a saltwater pool can be frustrating, but with the right knowledge and maintenance, it is possible to remove algae and prevent its recurrence. By understanding the different types of algae, balancing water chemistry, performing regular brushing and vacuuming, shock treatments, and following preventive measures, you can keep your saltwater pool clean, clear, and enjoyable for swimming. Remember to regularly test your pool water and seek professional advice if needed. Happy swimming!
