Here's a summary of parameters for Eleocharis parvula:

• Scientific Name: Eleocharis parvula
• Water Temperature: 68-82°F (20-28°C)
• pH Level: 6.0-7.5
• Water Hardness: Soft to moderately hard (2-15 dGH)
• Lighting: Moderate to high lighting levels are preferred for Eleocharis parvula. Provide at least 8-10 hours of light per day, preferably with full spectrum LED lighting.
• CO2 Requirement: While not strictly necessary, CO2 supplementation can promote healthier growth and faster carpeting, especially in higher light setups.
• Substrate: A nutrient-rich substrate is beneficial. Use a high-quality planted aquarium substrate designed for carpeting plants, or add root tabs to provide essential nutrients. Eleocharis parvula has a shallow root system, so a fine-grain substrate like sand or aquasoil is ideal.
• Propagation: Eleocharis parvula spreads through runners. Simply allow the runners to grow and form new plantlets, then separate and replant them as desired to encourage a lush carpet.
• Care Level: Moderate. Eleocharis parvula requires regular trimming to maintain its carpeting appearance. Trim any excess growth to prevent it from overshadowing other plants or blocking light.
• Special Considerations: This plant is commonly used as a foreground or carpeting plant due to its small size and grass-like appearance. It prefers stable water conditions and can tolerate a range of lighting levels, but higher light will encourage denser growth. Eleocharis parvula can be sensitive to sudden changes in water parameters, so it's important to acclimate it slowly to new conditions. Regular fertilization with a comprehensive liquid fertilizer containing micronutrients is recommended to support its growth.

By maintaining these parameters and providing proper care, Eleocharis parvula can create a lush and vibrant carpet in your aquarium, adding a beautiful and natural look to your aquascape.
