Ceratophyllum demersum (Hornwort) Care Guide (5cm Pot)

Ceratophyllum demersum, commonly known as Hornwort, is a fast-growing, easy-to-care-for aquatic plant that can thrive in a variety of water conditions. It’s ideal for beginners and perfect for improving water quality by absorbing excess nutrients.

Care Requirements:

• Light: Prefers moderate to high light. It can tolerate lower light conditions but may grow slower.
• Temperature: Thrives in temperatures between 15°C to 28°C (59°F to 82°F).
• pH Range: Tolerates a wide pH range of 6.0 to 8.0, with a preference for slightly acidic to neutral conditions.
• Water Hardness: Adapts to soft to hard water conditions.
• Water Flow: Can grow in a range of water flow conditions, from still to moderate current. Strong water flow can help keep it upright.
• Substrate: Can be planted in the substrate or left floating. It doesn’t require substrate for rooting and can float freely in the water column.
• Fertilization: Requires minimal fertilization. It can grow well without extra nutrients, but adding liquid fertilizers will encourage faster growth, especially in tanks with low nutrient levels.

Care Tips:

• Propagation: Propagates easily through stem cuttings. Simply snip off pieces and replant or let them float.
• Pruning: Regular pruning helps prevent overgrowth. Trim excess growth to maintain space in the tank and keep the plant healthy.
• Growth Rate: Hornwort grows very quickly and can become invasive if not managed. Regular trimming and removal of excess plant matter will keep it under control.
• Water Quality: Hornwort helps improve water quality by absorbing excess nutrients and reducing algae growth.

Additional Notes:

• Aquarium Placement: Can be used as a floating plant or planted in the substrate. It works well as a background or midground plant.
• Compatibility: Safe for fish, shrimp, and snails. It provides hiding spots for small fish and fry.
• Maintenance: Low-maintenance plant that requires occasional trimming. Keep the water clean with regular water changes and a good filtration system.

Hornwort is a great addition to any tank, offering fast growth, water purification benefits, and a lush, natural look to your aquarium.
