General Description

Common Name(s): Brazilian Waterweed, Elodea

Scientific Name: Egeria densa

Visual Description: Egeria densa is a fast-growing aquatic plant known for its bright green, densely packed leaves that form a lush, bushy appearance. Its long stems make it an excellent choice for background planting in aquariums, where it creates a natural, underwater forest-like effect.

Growing Conditions

Light Requirements: Moderate to high; it grows faster under brighter light conditions.

Water Requirements: Thrives in a wide range of water conditions, preferring soft to moderately hard water with good circulation.

Temperature Range: 18-28°C (64-82°F)

CO2 Requirements: CO2 supplementation is beneficial but not necessary for healthy growth.

Planting & Care

Substrate Preferences: Does not require a nutrient-rich substrate and can be left floating or anchored in the substrate.

Fertilisation Needs: Low; occasional fertilisation with a liquid fertiliser is sufficient.

Propagation Methods: Easily propagated by trimming and replanting stem cuttings.

Pruning/Tidying Up: Regular pruning is recommended to control its growth and maintain shape.

Placement

Aquarium Placement: Ideal for background placement in larger tanks or midground placement in smaller tanks. It can also be used as a floating plant.

Attachment: can be anchored in the substrate or left to float freely in the water column.

Spacing Requirements: Space stems approximately 5–10 cm apart to allow for growth and avoid overcrowding.

Compatibility

Aquarium Compatibility: Suitable for a variety of freshwater setups, including community tanks, biotopes, and aquascapes. Its fast growth can provide shelter for fry and small fish.

Pest/Disease Resistance: Generally hardy and resistant to pests and diseases, but may be susceptible to algae if light is too intense.

Special Requirements or Tips

Special Care Instructions: Egeria densa is known for its rapid growth, so regular trimming is essential to prevent it from overwhelming the tank. It is also an excellent oxygenator, helping to maintain healthy water conditions.

Seasonal Care: Maintain consistent conditions year-round. In outdoor ponds, protect from freezing temperatures during winter.

Ecological Impact

Invasiveness: Egeria densa can be invasive in outdoor water bodies. Use responsibly and avoid introducing it to natural water systems.

Benefit to Aquatic Environment: Provides excellent habitat for small aquatic life and helps oxygenate the water, contributing to a balanced ecosystem.
