Duckweed is one of the most common pond and aquarium plants around- and for good reason! It provides an attractive cover for the top of your water body with its small, circular leaves, and helps absorb excess nutrients, which is a must for any aquarium. It is also one of the easiest aquarium plants to maintain, requiring almost no special care- making it an ideal choice for beginners. Sold in 8 ounce portions.
Duckweed requires no special care. It will thrive in everything from low light to high light, from soft to hard waters. In fact, it is much harder to get duckweed not to grow versus getting it to grow- so care must be taken to ensure it doesn’t overrun your pond or aquarium. You should remove portions of it once every one to two weeks. Take care to not allow it to completely cover the surface of the water, as this can lead to the oxygen deprivation of any inhabitants.
