🌿 Duckweed (Lemna minor) – Natural Water Purifier & Fish Food Supplement

Duckweed, scientifically known as Lemna minor, is a tiny, free-floating aquatic plant that offers significant benefits to freshwater aquariums. Its rapid growth and nutrient absorption capabilities make it an excellent choice for maintaining a balanced aquatic environment.

🌟 Key Features

  • Natural Water Filtration: Duckweed absorbs excess nutrients like nitrates and phosphates, helping to reduce algae growth and maintain water clarity. 

  • Fish Food Supplement: Rich in protein, duckweed serves as a nutritious food source for various fish species.

  • Provides Shelter: Its floating mat offers cover for shy fish and fry, promoting a stress-free environment. 

  • Easy to Grow: Requires minimal care and can thrive in a variety of water conditions.

🪴 Care Guidelines

  • Lighting: Prefers moderate to high lighting; however, it can tolerate lower light conditions.

  • Water Parameters: Thrives in temperatures between 15–32°C, with a pH range of 6.0–8.0.

  • Water Flow: Best suited for calm or slow-moving water; strong currents can displace the floating mats.

  • Maintenance: Regularly remove excess duckweed to prevent overgrowth and ensure proper light penetration for other plants. 

⚠️ Considerations

  • Rapid Growth: Duckweed can double its biomass in just 48 hours under optimal conditions. Regular maintenance is essential to prevent it from covering the entire water surface. 

  • Potential Invasiveness: If left unchecked, duckweed can become invasive and may require controlled management.
