Why Choose Dwarf Water Lettuce

• Natural Filtration: Helps maintain water quality by absorbing excess nutrients like nitrates and phosphates.

• Water Movement: Prefers calm water; strong surface currents can damage leaves and roots.

• Fertilization: Usually thrives without additional fertilization, but occasional liquid nutrients can boost growth.

• Maintenance: Remove excess growth regularly to prevent overcrowding and maintain tank balance.

• Propagation: Reproduces through stolons which develop into daughter plants.

Compatible Tank Mates
