Effective Tips for Removing Algae from Pool

Having a clean and sparkling pool is the dream of every pool owner. However, one common problem that many pool owners face is the presence of algae. Algae not only make your pool look unsightly, but they also pose a health risk if left untreated. In this article, we will discuss effective ways on how to remove algae from your pool and prevent them from coming back.

Understanding Algae in Pools

Before we dive into the techniques for removing algae, it is important to understand what algae actually are. Algae are microscopic plants that thrive in moist environments, and pools provide the perfect breeding ground for them. They can enter your pool through rainwater, wind, or even on the skin of swimmers.

Types of Algae: There are different types of algae that can infest your pool, including green algae, yellow or mustard algae, and black algae. Green algae are the most common type and can turn your pool water green. Yellow or mustard algae give a yellowish-green appearance, while black algae are the most difficult to eliminate, as they have roots that penetrate deep into pool surfaces.

Effective Methods to Remove Algae

1. Shocking the Pool: Shocking your pool means adding an extra dose of chlorine to kill the algae. Start by balancing the pool’s pH level and then add a pool shock treatment according to the manufacturer’s instructions. Allow the shock treatment to circulate in the pool for at least 24 hours before proceeding to the next step.

2. Brushing the Pool Walls and Floor: Algae tend to cling to pool surfaces, making it important to brush the walls and floor to dislodge them. Use a pool brush with stiff bristles and scrub the entire pool, paying special attention to areas with visible algae growth. This physical agitation will help loosen the algae and expose them to the chlorine.

3. Pool Vacuuming: After brushing, it is crucial to vacuum the pool to remove the dislodged algae. Use a pool vacuum or automatic pool cleaner to ensure all the debris, including algae, is sucked up. Regularly check and clean the pool filter to prevent clogging due to algae accumulation.

4. Algaecide Treatment: Algaecides are chemicals specifically designed to kill and prevent the growth of algae. Look for an algaecide that is suitable for your pool type and follow the instructions provided by the manufacturer. Add the recommended amount of algaecide to the pool, ensuring it is evenly distributed.

5. Continuous Filtration and Water Circulation: To prevent algae from coming back, it is important to maintain proper filtration and water circulation in your pool. Run your pool pump and filter system for at least 8-10 hours a day to ensure efficient water circulation. Regularly clean and backwash your pool filter to remove any trapped debris.

6. Regular Pool Maintenance: Prevention is always better than cure when it comes to algae. Implement a regular pool maintenance routine that includes testing and balancing the pool’s chemical levels, brushing the pool surfaces, and skimming any debris from the water’s surface. By keeping your pool well-maintained, you can reduce the risk of algae growth.

Tips for Algae Prevention

While knowing how to remove algae from your pool is essential, preventing their growth in the first place is even better. Here are a few tips to prevent algae from becoming a recurring problem:

  • Maintain Proper Water Chemistry: Regularly test and balance the pool’s pH, chlorine, and alkalinity levels. This creates an environment where algae find it difficult to thrive.
  • Keep the Pool Clean: Skim the pool’s surface regularly to remove any debris or leaves that may provide nutrients for algae growth.
  • Keep the Pool Covered: When the pool is not in use, keep it covered with a pool cover. This prevents sunlight from reaching the water and inhibits algae growth.
  • Properly Circulate the Pool Water: Ensure your pool’s filtration and circulation systems are functioning optimally to prevent stagnant water, which algae love.

By following these preventive measures and maintaining regular pool care, you can enjoy a clean and algae-free pool all year round.


Algae can quickly turn your dream pool into a nightmare if not addressed promptly. Remember to shock your pool, brush and vacuum the surfaces, treat with algaecide, and continuously maintain proper filtration and water circulation. Implementing a regular pool maintenance routine and following the prevention tips mentioned will help keep algae at bay. With a little effort and diligence, you can enjoy a pristine and inviting pool for years to come.
