Regular water changes, approximately 25% bi-weekly, will help maintain water quality and clarity.

1. Lighting: Provide 8-10 hours of light each day using LED or fluorescent fixtures.
2. Water temperature: Maintain a temperature range of 22°C to 28°C (72°F to 82°F).
3. Water hardness: Ideal conditions are found in soft to moderately hard water, with a pH of 6.0 to 7.5.

Pruning is not typically necessary; however, general maintenance to remove any decaying leaves will keep the plant healthy and encourage growth.

Nutrient Requirements

For Umbrella Hairgrass to flourish, consider the following nutrient requirements:

• Light: Ensure moderate to high lighting conditions to promote robust growth.
• CO2: Supplemental CO2 injection is highly beneficial, with a target level of 20-30 mg/L. This enhances photosynthesis and overall vigor.
• Fertilization: A balanced liquid fertilizer can be added bi-weekly. Additionally, root tabs can be inserted into the substrate to provide essential nutrients directly to the roots.
