Vallisneria (Spiralis var. Red and Spiralis)
Overview
Vallisneria, both Spiralis var. Red and the standard green Spiralis, are popular in aquarium settings for their long, ribbon-like leaves that create a dynamic underwater landscape. These plants are excellent for adding height and contrast to the background, with the red variety providing a splash of color.
Position in Aquarium
- Location: Planted behind the Echinodorus and Hygrophila, stretching across the background to create a gradient effect from red to green.
- Grouping: Plant 3-4 shoots of each type, intermixed to enhance the depth and visual interest of the aquarium's background.
Care Requirements
Lighting
- Intensity: Moderate to high
- Duration: 10-12 hours per day to support healthy growth and color development in the red variety.
Water Conditions
- Temperature: 20-28°C (68-82°F)
- pH: 6.5-7.5
- Hardness: 4-18 dKH
Substrate
- Type: Prefers a rich, sandy substrate that allows for easy root expansion.
CO2
- Addition: Not necessary but can promote faster growth and better overall plant health.
- Rate: Moderate, especially beneficial for the red variety to maintain its vibrant color.
Fertilization
- Macro Nutrients: Regular supplementation with a balanced aquarium fertilizer.
- Micro Nutrients: Iron is particularly important for enhancing the red coloration of Spiralis var. Red.
Pruning and Maintenance
- Pruning Frequency: As needed to control height and spread.
- Trimming Technique: Cut at the base near the substrate to remove older or overly long leaves.
Propagation
- Method: Runners are sent out from the base of the plant, which then develop into new plants that can be separated and replanted.
- Growth Rate: Fast, which makes it ideal for quickly filling in background areas.
Common Issues
- Leaf Tip Burn: Can occur if the water is too hard or if there is excessive light.
- Crowding: Due to its fast growth, Vallisneria can crowd out slower-growing plants if not regularly maintained.
Additional Tips
- Flow Resistance: Vallisneria is very tolerant of water flow, making it suitable for placement near filter outputs.
- Visual Planning: Use the varying heights and colors of Vallisneria to create a natural, tiered look in the aquarium's background.
