Hygrophila corymbosa (Thailand)

• Fast growing plant
• Hardy
CO2: While not essential, CO2 supplementation can boost growth and enhance leaf coloration, especially in high-light environments.

Appearance

• It features large, elongated green leaves that can develop red or bronze hues under strong lighting.

Growth rate

It is a fast-growing plant, making it a good choice for quickly filling out an aquarium.

Lighting

• Moderate to high light is recommended for optimal growth and vibrant coloration, though it can tolerate lower light levels.

Placement

• Ideal for the background or midground of aquariums, depending on the tank size.
Planting in small groups with space between stems allows for proper light penetration and water circulation.

Algae

• It's important to maintain good water quality and provide adequate, but not excessive, lighting to prevent algae issues.
• Potential Algae Issues:
• BBA (Black Beard Algae):
  This can be a problem if there are fluctuations in CO2 levels or if water circulation is poor.
• Green Spot Algae:

This type of algae can appear on leaves if there are high levels of nitrates or phosphates.

• General Algae Growth:

Excess nutrients, especially nitrates and phosphates, can fuel overall algae growth.

• Algae on Leaves:

Potted Hygrophila plants can sometimes exhibit small, firm overgrowths on leaves, but these are typically harmless and not caused by pests or disease.
