How Do I Remove Algae From My Pool?

Shock your pool, brush the walls and floor, and vacuum thoroughly. For lasting algae prevention, try our AquaDoc Pool Algaecide.

Why Does Algae Grow in Pools?

Algae can develop due to several reasons, including:

• Imbalanced Water Chemistry: Low chlorine levels create the perfect environment for algae growth.

• Poor Circulation: Weak water movement allows algae to thrive in stagnant areas.

• Debris and Contaminants: Leaves, dirt, and organic matter provide nutrients for algae.

• Warm Temperatures and Sunlight: Algae growth is faster in hot weather or direct sunlight.

Steps to Remove Algae From Your Pool

Follow these steps to eliminate algae effectively:

1. Test and Balance Your Pool Water

• Use a pool test kit to measure pH, chlorine, and alkalinity.

• Adjust your pH to 7.2-7.6 and ensure chlorine levels are adequate.

2. Brush Your Pool Walls and Floor

• Use a pool brush with stiff bristles for effective scrubbing.

• Pay extra attention to corners, steps, and shaded areas where algae often hide.

3. Vacuum Your Pool

• Use a manual vacuum to remove algae debris directly.

• Avoid using an automatic pool cleaner, as it can spread algae further.

4. Shock Your Pool

• Choose a calcium hypochlorite shock for green algae or high-strength algaecide for stubborn cases.

• Apply the shock treatment in the evening for best results.

5. Run Your Pool Filter Continuously

• Run your pool filter for at least 24-48 hours after shocking.

• Clean your filter thoroughly afterward to prevent algae from re-entering your pool.

6. Use an Algaecide for Extra Protection

• Select a broad-spectrum algaecide designed for pool use.

• Follow the manufacturer's instructions for proper dosing.

7. Clean Pool Accessories and Tools

• Soak pool brushes, nets, and skimmers in a chlorine solution to kill any algae spores.

• Rinse all items thoroughly before placing them back in your pool.

8. Prevent Algae Growth in the Future

• Maintain chlorine levels between 1-3 ppm consistently.

• Use a pool cover when the pool isn’t in use to block debris and sunlight.

• Shock your pool weekly during hot weather to reduce algae risks.

• Regularly brush and vacuum your pool to prevent buildup.

Types of Pool Algae and How to Treat Them

• Green Algae: Most common and easy to remove with brushing, shocking, and filtration.

• Yellow Algae (Mustard Algae): Requires strong brushing and heavy shock treatment.

• Black Algae: The toughest type, often found in cracks, requires scrubbing, shock, and an algaecide designed for black algae.

Staying consistent with pool care is the best way to avoid algae problems. By maintaining water balance, keeping your pool clean, and acting quickly if algae appear, you can enjoy clear and safe swimming conditions throughout the season. With regular effort and the right techniques, your pool can stay inviting and free from unwanted growth.
