Looking for a fast-growing, nutrient-dense plant that feeds your fish, filters your water, and practically grows itself? Duckweed (Lemna minor) is your go-to aquaponics ally. Small in size, big in performance—this little floater brings powerful benefits to any tank or grow bed.
What Makes Duckweed a Smart Choice?
-
Ultra-Fast Growth
Duckweed is one of the fastest-growing aquatic plants in the world—capable of doubling in mass every 24 to 48 hours under ideal conditions. That means a continuous, renewable food source for your fish. -
High Protein, Natural Feed
With protein levels reaching up to 40%, Duckweed is a powerhouse food source for tilapia, koi, mollies, goldfish, tadpoles and more. It’s soft, easy to digest, and especially ideal for fry and fingerlings. -
Water Cleaner & Nutrient Balancer
Duckweed acts like a floating biofilter, quickly absorbing excess nitrates, phosphates, and even trace heavy metals—leaving your water cleaner and healthier for both plants and fish. -
