Spirodela polyrhiza, also known as giant duckweed, is a fast-growing floating plant from Tropica’s 1-2-Grow! line. It features vibrant green, rounded leaves that float gently on the water’s surface, creating natural shade and a calming, lagoon-like effect in aquariums. Each frond produces long, trailing roots that add texture and are perfect for shrimp and fry to hide in.
This plant plays an essential role in water quality improvement by absorbing excess nutrients and light, making it especially helpful for reducing algae growth.
Key Features:
• Fast-growing floating plant with lush green leaves
• Excellent for nutrient absorption and algae control
• Provides shade and shelter for fish and invertebrates
• Perfect for aquariums, paludariums, and open-top tanks
• Grown in sterile 1-2-Grow! cup – pest- and algae-free
Usage Tips:
• Simply place the plant on the water surface—no planting needed
• Ensure it doesn’t cover the entire surface to maintain gas exchange
• Trim regularly to control spread and maintain light levels for submerged plants
