Algae in pools are often caused by factors such as improper chemical balance, poor filtration, and insufficient cleaning. To get rid of algae, you’ll need a structured plan that includes balancing your pools chemistry, brushing affected areas, and using algaecides. In this post, we’ll walk you through everything you need to know about removing algae effectively and preventing it from returning.
The Basics of Pool Algae
What Is Algae and Why Does It Occur?
Algae are plant-like organisms that thrive in water, particularly in warm, stagnant, and nutrient-rich environments. It can turn your pool water green, yellow, or even black, creating unsightly and unsafe conditions. Algae growth is often due to factors like improper pH levels, high phosphate concentrations, or inadequate filtration and circulation.
Types of Pool Algae
- Green Algae: The most common type, often floating or sticking to pool walls.
- Yellow (Mustard) Algae: A tougher variety that clings to surfaces and hides in corners.
- Black Algae: The most stubborn, forming dark spots that penetrate deep into plaster or concrete surfaces.
How to Kill Algae in Pool: Step-by-Step Guide
1. Test and Balance Your Pool Water
Using a pool test kit, measure the pH, alkalinity, and chlorine levels. Adjust your chemicals to achieve balanced water. Algae thrive in pools with unbalanced water, so this step is crucial. Aim for a pH level between 7.47.6 and free chlorine levels of 13 ppm.
2. Brush the Pool Walls and Floors
Scrubbing the affected surfaces is a critical step in removing algae. Use a pool brush designed for your pool’s material to dislodge algae deposits from walls and floors.
3. Shock Your Pool
To kill algae, superchlorinate your pool using pool shock. Make sure to use the appropriate amount for your pool size to raise the chlorine level significantly, which destroys algae at a cellular level.

Your pool’s filtration system is your best ally in clearing out dead algae. Keep the pump running 24/7 until the water becomes clear.
5. Use an Algaecide
Applying an algaecide can help prevent algae regrowth after shocking the pool. Select a product that is suited for the type of algae in your pool.
Preventing Algae in Your Pool
