Algae growth in your pool can quickly turn crystal-clear water into a green, murky mess, and if left untreated, it can make your pool unsafe and unappealing for swimmers. An algae bloom can occur rapidly, posing health risks due to bacteria or toxins, and making the pool unsafe for swimming. Stubborn algae can be tricky to deal with, but with the right approach, you can eliminate it and restore your pool to its sparkling condition.
In this article, we’ll explore different methods for removing algae, focusing on both chemical treatments and mechanical cleaning techniques. We’ll also cover the role that robotic pool cleaners—especially Dolphin models—can play in effectively managing algae buildup.
Understanding Algae in Pools
Algae in your pool are microscopic plants that thrive in warm, sunlit environments, making your pool an ideal place for them to grow. There are several types of pool algae, but the most common are:
Green Algae: The most widespread and easiest to treat, green algae float in the water or cling to the pool walls.
Yellow/Mustard Algae: Often found in shady areas of the pool, yellow algae are tougher to treat and require more aggressive methods.
Black Algae: The most stubborn of all, black algae burrow deep into the pool surfaces and are resistant to typical treatments.
Regardless of the type, algae growth can make your pool water cloudy, slippery, and unsafe, so it’s essential to take immediate action once you notice it.
1. Using a Pool Brush for Brushing and Scrubbing
A green pool is a clear sign of algae infestation, requiring immediate and thorough cleaning to restore its clarity.
The first step in removing stubborn algae is to physically scrub it off pool surfaces.
Tools: Use a pool brush with stiff bristles, particularly for tough algae like black algae, to break up the colonies. Scrub the pool walls, floor, steps, and even hard-to-reach places like behind ladders.
Best Practices: Start from the shallow end and work your way to the deeper sections of the pool. Be thorough, especially with black algae, as its roots can penetrate porous surfaces like plaster and grout.
While brushing alone won’t get rid of algae, it helps loosen it so the next steps can be more effective.
2. Shock Your Pool
Algae thrive when chlorine levels drop, so you’ll need to hit them with a high dose of chlorine to stop them in their tracks. Green pool algae, the most common type, can be effectively treated with a high dose of chlorine.
How to Shock: Follow the instructions on your pool shock product to determine the right amount. Generally, you’ll need 1-2 pounds of shock per 10,000 gallons of pool water. For severe algae growth, double or even triple this amount to deliver a high dose of chlorine.
Super Chlorination: For very stubborn algae like mustard or black algae, a process called super chlorination may be necessary. This involves raising the chlorine level even higher than a typical shock treatment and letting it circulate for at least 24 hours.
Timing: Shock your pool at dusk or night to prevent the sun from burning off the chlorine too quickly, which can reduce its effectiveness.
3. Algaecides
In addition to chlorine, algaecides are specialized chemicals that target algae. While not always necessary, they can provide extra help, particularly for resistant algae types.
Copper-Based Algaecides: These are effective for green and black algae but should be used carefully, as too much copper can stain your pool and damage equipment.
Quaternary Ammonium Algaecides (Quats): These are foaming algaecides best used for prevention and light algae growth. They are less effective on severe algae infestations.
Polyquat Algaecides: A non-foaming option that works well for eliminating mustard and green algae. It’s also useful as a preventative measure.
4. Vacuuming to Waste
Once you’ve brushed the algae off the walls and floor and shocked the pool, you’ll need to remove the dead algae from the water. Using a vacuum to waste setting ensures that the algae get removed from your pool entirely, rather than going through the filtration system where it could potentially recirculate. Using the vacuum to waste setting ensures that the algae do not pass through the pool filter, preventing potential recirculation.
Manual Vacuuming: Connect your manual vacuum to your skimmer, but instead of setting it to “Filter,” set it to “Waste.” This bypasses your filter system and sends the debris out of the pool. Slowly and carefully vacuum the pool floor, as moving too fast can stir up debris.
Why It’s Important: Without vacuuming to waste, the dead algae can cloud up the water again, making your pool dirty and slowing down the recovery process.
5. Dolphin Robotic Pool Cleaners: A Modern Solution for Algae Control
Robotic pool cleaners can be a game-changer for pool owners looking for an automated way to deal with stubborn algae. And when it comes to robotic cleaners, Dolphin stands out as a top choice. Incorporating a Dolphin robotic cleaner into your pool maintenance routine can significantly reduce the likelihood of algae growth.
How Dolphin Pool Cleaners Help: Dolphin robotic pool cleaners are equipped with powerful scrubbing brushes and advanced navigation systems, allowing them to thoroughly clean pool walls, floors, and waterlines. This is especially important for dealing with algae, which often clings to surfaces.
Effective Against All Algae Types: Dolphin’s high-speed scrubbing brushes and multi-layer filtration systems can handle even the toughest algae, including black algae. Unlike manual cleaning, where you might miss spots, Dolphin’s smart navigation ensures that every inch of your pool is cleaned thoroughly.
Energy Efficiency: Dolphin pool cleaners operate independently of your pool’s pump and filtration system, which reduces energy consumption and wear on your equipment. Plus, they work quietly and efficiently, so you can run them frequently to prevent algae from taking hold.
Ease of Use: With Dolphin’s plug-and-play operation, you simply drop the cleaner into the pool and let it do the work. For pool owners dealing with frequent algae outbreaks, you can set cleaning schedules so the Dolphin runs at regular intervals, keeping your pool consistently clean.
By incorporating a Dolphin robotic cleaner into your algae removal routine, you not only save time and effort, but you also ensure a more thorough and consistent cleaning.
6. Maintain Proper Water Balance
After you’ve removed the algae, maintaining the proper chemical balance in your pool is essential to prevent future growth. Maintaining the proper chemical balance is crucial to remove pool algae and prevent its return. Here are some key parameters to monitor:
Chlorine Levels: Keep free chlorine levels between 1-3 ppm (parts per million) to ensure your pool is sanitized.
pH Levels: The ideal pH range is 7.2-7.6. High pH levels can reduce the effectiveness of chlorine.
Alkalinity: Maintain alkalinity levels between 80-120 ppm to stabilize the pH levels.
Cyanuric Acid (CYA): CYA protects chlorine from being destroyed by sunlight, but too much can reduce chlorine’s effectiveness. Keep CYA levels between 30-50 ppm.
By regularly testing and adjusting your pool’s chemical levels, you can prevent algae from returning.
Conclusion: Stay Ahead of Algae with Consistent Care
Algae can be stubborn and frustrating to deal with, but with a combination of brushing, chemical treatments, vacuuming, and the help of an automated cleaner like Dolphin, you can eliminate it and keep your pool sparkling clean. Remember, prevention is the best cure. Regular maintenance, balanced chemicals, and consistent use of a high-quality robotic cleaner will keep algae at bay and make pool care much easier in the long run.
FAQs
How often should I shock my pool to prevent algae?
Shocking your pool every 1-2 weeks during the swimming season can help prevent algae growth, especially if your pool gets heavy use or if you live in a hot climate.
Can I use a Dolphin robotic cleaner for all types of algae?
Yes! Dolphin cleaners are effective against all types of algae, including green, yellow, and black algae, thanks to their powerful scrubbing brushes and advanced filtration.
What is the best way to prevent algae from growing in my pool?
Maintaining proper chemical levels, regularly running your pool pump, and using an automated cleaner like Dolphin can help prevent algae from growing.
How long does it take to get rid of algae in a pool?
It depends on the severity of the algae growth. Green algae can usually be eliminated within a day or two with shock treatment and vacuuming. More stubborn algae, like mustard or black algae, may take several days and require multiple treatments.
How does pH level affect algae growth?
If the pH level is too high, it can reduce the effectiveness of chlorine, making it easier for algae to grow. Keeping the pH level in the ideal range (7.2-7.6) helps chlorine do its job and prevents algae from thriving.
