Oxygen Plants

Crabber

Crab crab (Aloides Stratiotes) is a unique, hardy oxygen plant that floats on the surface of the water. The pond plant is characterized by pointed, star-shaped leaves with which the plant keeps sunlight out of the water. Because of these characteristics, crab shears are also called ''water soldier.''

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 Crab Shaving

Pond Advice

Crabberries, also known as "water soldiers," play a crucial role in purifying pond water. They are able to filter phosphates and nitrates from the water, contributing to a healthy pond. By blocking excessive sunlight, it also prevents the growth of algae. In addition, the plant helps stabilize water values such as GH value, PH value and KH value.

Crab shrubs are fast-growing pond plants that grow fastest with warm temperatures. During the winter months, the plant's growth stops and they go into dormancy. The plant can grow up to 50 inches in diameter. The plant continues to grow annually and becomes more beautiful with time.

Crabweed is a floating oxygen plant and can simply be laid down on the surface of the water. The plant will then float and continue to grow this way.

Stratiotes aloides

Crab crab is a popular pond plant that floats on the pond surface. The oxygen plant is a great addition to almost any pond and is often chosen for its low maintenance properties and vibrant foliage. Crabber is a strong and hardy plant that releases oxygen to the water, keeping your pond and the life in it healthy. It is a great oxygen plant that totally brightens up your pond. In addition, the oxygen plant protects the pond water from warming up which prevents algae.

Crabgrass plants & fish

Crabberry generally goes well with fish, provided there are enough oxygen plants in the pond. Koi are known to demolish any aquatic plant, they are less likely to do so with crab feather because this aquatic plant takes up little space due to its floating properties and is not attractive to nibble on due to the hard dots on the leaves. There is always the risk that crab crabber can be eaten by pond fish, but the likelihood is less.

Wild crabgrass

Crabgrass (Stratiotes aloides) is an interesting and striking aquatic plant found mainly in the temperate regions of Europe. In the wild, as in the pond, crabgrass has:

  • Floating character: In spring and summer, crabgrass floats with its rosette of sharp leaves just below or on the surface of the water. This helps collect sunlight for photosynthesis.
  • Sinking behavior: By winter, the plant sinks to the bottom of the water to facilitate overwintering and rises to the surface again the following spring.
  • Relationship to algae: Crabgrass can help limit the growth of algae by competing for nutrients in the water.

Appearance of crabber

The crab crab exhibits a striking appearance, inspired by its crab-like shape with long, pointed leaves that fan out gracefully from the center of the plant. These leaves are subtly toothed and can therefore be prickly to the touch. They envelop themselves in a fresh light green hue. Centrally, in the heart of the plant, elegant white blossoms flaunt a hint of yellow. Majestically, the plant rises some 20 centimeters above the water.

Crab crab floats upside down or sinks to the bottom

Crab crab can indeed float upside down or sink to the bottom. You see this especially in new ponds or in ponds with few nutrients. They get their nutrition from the bottom and once they have absorbed enough nutrients and become stronger, they will return to the surface. This behavior is normal, especially for young crab rays. Under the influence of sunlight, they will adapt and float upright within a few days. So don't worry. Moreover, crab shoals enter a rest period in the fall, which may also explain why they sink to the bottom.

Buy crab claw

Buying crabgrass is a good choice for pond and aquarium enthusiasts looking for an underwater plant that can improve water quality and add a natural look to their aquatic environment.

Crab feather pond

Crabweed is a valuable aquatic plant for ponds, characterized by its long, narrow leaves that resemble crab legs. This plant floats on the water surface and helps improve water quality by absorbing excess nutrients and controlling algae. In addition, crabgrass provides hiding places for pond inhabitants such as fish and insect larvae, and it contributes to a balanced pond ecosystem. It is a valuable addition for pond enthusiasts who strive for clear and healthy water.
