## Features

- 10 STEMS - 1 Bunch -Excellent natural oxygenator for aquariums and ponds. Elodea Densa is a powerful aquatic plant that significantly improves water quality by absorbing carbon dioxide and releasing oxygen. It helps maintain a balanced ecosystem and supports the health of fish, and other aquatic life. You will receive rootless plants, 12–25 cm in length. Please note: they are not safe for shrimp.
- Promotes crystal clear water and helps control algae growth. Due to its fast-growing nature, Elodea Densa competes with unwanted algae for nutrients, naturally reducing their presence. It acts as a biological filter, keeping the water clean and clear without the need for chemicals.
- Provides ideal shelter and breeding ground for aquatic creatures. The dense, bushy foliage creates a safe and natural environment for small fish, fry. It offers protection from predators, reduces stress, and supports natural behaviours and spawning.
- Easy to grow and low maintenance. This hardy plant adapts well to a wide range of conditions, making it suitable for beginners and experienced aquarists alike. It grows in cold or warm water, with or without substrate, and requires no special lighting or CO₂ systems.
- By absorbing excess nutrients, Elodea Densa limits algae growth and supports clearer, cleaner water without the use of chemicals, making it an environmentally friendly, low-effort choice for maintaining a healthy, well-balanced aquatic ecosystem.
