Controlling Algae Growth During the Summer

The only Master Aquascape Certified Contractors in Iowa


During the summer months, one common issue that many people face is the uncontrolled growth of algae in their water bodies. Algae can quickly take over ponds, pools, and other water features, creating an unsightly and potentially hazardous environment. In this article, we will explore various methods and strategies to effectively control algae growth and maintain clear and healthy water throughout the summer.

1. What is algae and why does it grow in water?

Algae are simple, plant-like organisms that thrive in water. They utilize sunlight, carbon dioxide, and nutrients present in the water to carry out photosynthesis, enabling their growth. Algae can multiply rapidly under favorable conditions, leading to the formation of green, slimy, or discolored water.

2. The problems caused by algae growth

Uncontrolled algae growth can cause several problems for water bodies. Firstly, it can hinder the aesthetic appeal of the water, making it appear dirty and uninviting. Additionally, algae can reduce oxygen levels in the water, which can negatively impact fish and other aquatic life. It can also clog filters, pumps, and other water equipment, leading to operational issues and increased maintenance requirements.

Controlling Algae Growth

To effectively control algae growth, it is essential to implement a combination of preventive measures and targeted treatments. Here are some strategies to consider:

3. Maintaining proper water chemistry

One of the fundamental aspects of algae control is maintaining proper water chemistry. This includes monitoring and adjusting pH levels, alkalinity, and calcium hardness. By keeping these parameters within the recommended range, you create an environment that is less favorable for algae growth.

4. Using algaecides

Algaecides are chemical treatments specifically designed to kill or inhibit the growth of algae. They are available in various formulations, such as copper-based, quaternary ammonium compounds, and hydrogen peroxide-based products. When using algaecides, it is crucial to follow the manufacturer’s instructions and dosage recommendations to ensure effective and safe treatment.

5. Implementing physical removal methods

Physical removal methods involve manually removing algae from the water. This can be done using tools like skimmers, nets, and brushes. Regularly skimming the water surface and manually brushing algae off surfaces can help prevent its accumulation and promote a cleaner environment.

6. Utilizing natural methods to control algae

In addition to chemical treatments, there are several natural methods you can employ to control algae growth in your water bodies. These methods are eco-friendly and can help maintain a balanced ecosystem:

  • Aquatic Plants: Introducing aquatic plants, such as water lilies, water hyacinths, and submerged oxygenators, can help compete with algae for nutrients and sunlight. These plants absorb excess nutrients, reducing the available resources for algae growth.
  • Aeration: Installing an aeration system in your pond or water feature can help improve water circulation and increase oxygen levels. Algae thrive in stagnant water, so by keeping the water moving and well-oxygenated, you create an environment less favorable for their growth.
  • Barley Straw: Barley straw is a natural method used to control algae. When placed in the water, the straw releases compounds that inhibit algae growth. It is an effective preventive measure and can be used in ponds, water gardens, and small water features.
  • Beneficial Bacteria: Adding beneficial bacteria to your water can help break down organic matter, reducing the nutrient load that fuels algae growth. These bacteria create a healthier and more balanced ecosystem, making it harder for algae to take over.

Prevention and Maintenance

To maintain algae-free water throughout the summer, it is essential to incorporate preventive measures and regular maintenance routines. Here are some key considerations:

7. Regular cleaning and maintenance

Regularly cleaning and maintaining your water bodies is crucial to prevent algae growth. This includes removing debris, skimming the surface, and cleaning filters to ensure proper water circulation and filtration.

8. Proper filtration system

Investing in a quality filtration system is essential for effective algae control. A robust filtration system will remove debris and particles from the water, reducing the nutrient load and providing a healthier environment for aquatic life.

9. Managing sunlight exposure

Algae thrive in sunlight, so it is important to manage the amount of direct sunlight your water bodies receive. Consider installing shade structures or using floating plants to provide some shade and reduce the availability of sunlight for algae growth.

10. Controlling nutrient levels

Regularly monitoring and controlling nutrient levels, especially phosphates and nitrates, can significantly inhibit algae growth. These nutrients act as fertilizers for algae, so by reducing their presence in the water, you can limit their growth potential.

Dealing with Specific Types of Algae

Different types of algae may require specific treatments and approaches. Here’s a brief overview of how to deal with common types of algae:

11. Green algae

Green algae are the most common type of algae found in water bodies. They can be controlled using algaecides, physical removal methods, and maintaining proper water chemistry.

12. Blue-green algae

Blue-green algae, also known as cyanobacteria, can be harmful to humans and animals. It is crucial to address blue-green algae blooms promptly. Contacting a professional or your local health department for guidance on safe removal is recommended.

13. Mustard algae

Mustard algae often appear as yellow or brownish patches on surfaces. It can be stubborn to eliminate but can be treated with algaecides and consistent brushing.

14. Black algae

Black algae are particularly difficult to eradicate due to their deep root systems. Scrubbing affected surfaces and using algaecides specifically formulated for black algae can help control its growth.

Controlling algae growth during the summer is essential to maintain clear and healthy water in your ponds, pools, and other water features. By implementing a combination of preventive measures, targeted treatments, and regular maintenance routines, you can effectively keep algae at bay.

Start by maintaining proper water chemistry and utilizing algaecides when necessary. Physical removal methods, such as skimming and brushing, can also help control algae growth. Additionally, consider incorporating natural methods like aquatic plants, aeration, barley straw, and beneficial bacteria to create a balanced ecosystem.

Preventive measures and regular maintenance are key to algae control. Clean and maintain your water bodies regularly, invest in a quality filtration system, manage sunlight exposure, and control nutrient levels. By addressing specific types of algae appropriately, such as green algae, blue-green algae, mustard algae, and black algae, you can target their growth effectively.

Remember, consistent efforts and a proactive approach are vital in keeping algae growth under control. With proper care, you can enjoy clean, clear water throughout the summer months.
