Oxygen Plants

Waterweed

Waterweed (Elodea Densa) is a hardy oxygen plant that grows up to 1 meter, ideal for ponds and aquariums. It keeps water clear, provides plenty of oxygen and is easy to maintain: place it in your pond or aquarium and let nature do its work.

Simon van der Velde

For oxygen plants, I recommend a minimum of 10 to 12 individual plants per m³ (1000 liters of water) and 2 baskets of 8 plants per m². The amount needed depends on how quickly you want the pond to balance and your visual requirements.

Frequently asked questions about Waterweed

Pond Advice

Waterweed is essential because of its ability to produce a lot of oxygen, grow quickly, and purify the water. It helps stabilize water values such as GH, PH, and KH. In addition, it is a natural algae fighter, makes the water nutrient poorer, reducing the opportunity for algae to form, and provides shelter for fish and other aquatic animals.

To keep waterweed healthy it is important that the pond is set up correctly. Throw waterweed loose in the pond, leave the wire around the plant so that it sinks to the bottom and finds its way into the pond by itself. Waterweed requires little to no maintenance.

The recommendation is to plant a minimum of 5 to 6 individual plants per square meter so per 1000 liters of water. This depends on how quickly you want the pond or water feature to be balanced.

Waterweed buy from Vdvelde, all our plants are delivered directly from our own family water plant nursery. We pack the plants so that they arrive at our customers in good condition. We also offer a 100% growth and flowering guarantee.

A bunch of waterweed consisting of 6 individual plants costs 19,95,- with us. When waterweed is purchased from us in a bunch of 12 individual plants costs only 34,95,-.

Elodea

Waterweed is a great plant for your pond and is found mostly in shallow ponds, lakes, streams and rivers. It is a great addition to your pond and you probably choose it because of its ease of maintenance and vibrant leaves. Waterweed grows quickly and can help control algae growth by competing for light and nutrients. It is an excellent oxygen provider, providing oxygen to the fish and other animals in your pond. In addition, it is perfect for shaded areas in your pond during the hot summer months.

Waterweed for the aquarium

Waterweed in your aquarium is a perfect oxygen producer and you can place it in the background as well as in the middle zone. It absorbs a huge amount of waste products and thus acts as a kind of filter that keeps your water clean. The plant does not require much to grow well, but for best results place waterweed in somewhat colder water with normal lighting. With more lighting, the water may be a bit warmer, up to about 26 degrees. Because waterweed grows quickly, you should prune it regularly. This is easily done by cutting off a piece. The cut off part can be replanted if necessary.

What is waterweed?

Waterweed is a fast-growing plant that needs nutrients to grow optimally. By absorbing these nutrients, waterweed competes with algae such as filamentous and floating algae. A good amount of oxygenated plants, including waterweed, counteracts algae formation.
