Common Duckweed, Lemna Minor – Surface Floating Plant
Portion: Approx. 10 grams
Duckweed is a small aquatic floating plant found around the world. Commonly measuring between 3 to 10mm in length, duckweed floats on the water surface in colonies and is not attached to the bottom. Duckweed plants have a very fine root hanging from it. Each plant can have one leaf or up to three leaves, known as fronds, about the size of a pencil rubber, with a single root hair.
The main means of reproduction is vegetative, with two daughter plants budding off from the adult plant. A new duckweed plant can be produced every 24 hours, even in moderate sunlight outdoors or in low-lit aquariums.

Added 10g of duckweed to my 10-gallon aquarium. It spread quickly within 48 hours and covered the surface evenly. The plant stayed healthy even in low light. Easy to maintain and helps reduce algae growth.
Stewart Nolan –
Grew well in my low-light tank. The fronds are small but dense. I noticed new plants forming every day. It’s a good natural cover for fish and helps balance nutrients.

Perfect for beginners. The duckweed spread fast and stayed green without needing extra care. I’ve seen it grow in both indoor and outdoor setups. Very effective at reducing algae.
