Thriving in the Brackish Balance: Ruppia maritima (Widgeon Grass)

Bring the beauty and biodiversity of brackish ecosystems to your aquarium with Ruppia maritima, also known as Widgeon Grass. This fascinating submerged aquatic plant thrives in the unique salinity range of brackish water, offering a captivating addition to your marine or brackish water setup.

Key Features:

• Brackish Water Specialist: Unlike freshwater or saltwater-only plants, Ruppia maritima flourishes in the delicate balance of brackish environments, tolerating a salinity range of approximately 5-18 ppt (parts per thousand). This makes it a perfect choice for aquariums simulating estuaries, coastal marshes, or brackish lagoons.
• Oxygenation & Filtration: Like all aquatic plants, Ruppia maritima contributes significantly to oxygenation and water filtration. It helps absorb excess nutrients, improving water quality and creating a healthier environment for your fish and invertebrates.
• Natural Habitat Creation: Provides a natural and visually appealing habitat for small fish and invertebrates, offering hiding places, spawning grounds, and grazing opportunities. Its delicate, grass-like leaves create a realistic and aesthetically pleasing underwater landscape.
• Easy to Maintain (with proper conditions): While requiring specific salinity, Ruppia maritima is relatively low maintenance once established. Good lighting and consistent water parameters are crucial for its successful growth.
• Nutrient Uptake: Effectively absorbs nitrates and phosphates from the water column, reducing the need for frequent water changes.
• Versatile Growth Habit: Grows in dense clumps, offering excellent coverage and visual appeal. Can be planted in substrate or allowed to float freely.

Ideal Growing Conditions:

• Salinity: 5-18 ppt (parts per thousand) – Crucial for survival. Regular testing is recommended.
• Temperature: 15-28°C (59-82°F)
• Lighting: Moderate to bright indirect light. Avoid direct, intense sunlight which can scorch the leaves. Consider using aquarium LED lights tailored to plant growth.
• Substrate: Fine sand or a mix of sand and gravel is ideal. Planting in a suitable substrate is recommended for optimal growth, but it can also thrive free-floating.
• Water Movement: Gentle water movement is beneficial, but avoid strong currents.

Planting & Care:

1. Acclimation: Gradually introduce the Ruppia maritima to your brackish water tank to avoid shock.
2. Planting (Optional): Gently plant the root system into the substrate, ensuring the leaves remain above the substrate.
3. Maintenance: Regularly monitor salinity and water parameters. Prune any overgrown or decaying leaves as needed. Regular water changes are still important, but the plant will lessen the frequency needed compared to tanks without plants.

What You Get:

• A healthy portion of Ruppia maritima ready to be added to your brackish water aquarium. (Specific quantity will vary depending on the chosen size option).

Note: Successful cultivation requires accurate salinity maintenance. Invest in a reliable refractometer or hydrometer to monitor your water's salinity levels regularly. Improper salinity will result in plant death. This plant is not suitable for freshwater or full saltwater aquariums.
