Vallisneria gigantea (5cm Pot) Care Guide

Vallisneria gigantea, commonly known as Giant Vallisneria, is a tall, robust aquatic plant with long, ribbon-like leaves that can reach impressive heights. It is perfect for creating a lush background in larger aquariums. Here’s a concise care list:

Care Requirements

• Tank Size: Suitable for tanks of 20 gallons or larger due to its large size.
• Lighting: Moderate to high; bright light promotes healthy growth and vibrant green coloration.
• Temperature: 22–28°C (72–82°F); ideal for tropical setups.
• pH Range: 6.0–7.5; grows best in slightly acidic to neutral water.
• Water Hardness: Soft to moderate (2–12 dGH).
• Substrate: Nutrient-rich substrate; benefits from root tabs for optimal root development and growth.
• Growth Rate: Fast; regular pruning is needed to control size and maintain appearance.
• CO2 Requirement: Not mandatory, but CO2 supplementation will boost growth and overall health.

Key Tips

• Prune regularly to prevent it from overtaking the tank and to encourage healthy new growth.
• Ideal for the background in large aquascapes, as it can grow quite tall (up to 3 feet or more in ideal conditions).
• Provide stable, bright lighting to ensure vibrant green leaves and strong growth.

Vallisneria gigantea is a great choice for aquariums that can accommodate its size. It adds a dramatic, lush background and thrives with good lighting, a nutrient-rich substrate, and periodic pruning.
