Oxygen Plants

Marimo moss balls

Marimo (Cladophora aegagropila), also known as moss ball, is actually an algal bulb originating from Japanese traditions. This hardy oxygen plant can live up to 100 years and reach 10 centimeters in diameter. In Japanese culture, Marimo symbolize happiness and purity: they are known for their longevity and ability to purify water.

Oxygenating plants are a must for any pond! Sufficiently oxygenating underwater plants in the pond will keep you from needing a pump and filter. Oxygen plants filter the water and block the sun. This causes the water to heat up less which results in less algae. Oxygen plants also provide shelter for fish from impending danger. All of our oxygen plants are hardy and are supplied from our own aquatic plant nursery with a 100% growth and flowering guarantee. 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 Marimo

Pond Advice

Marimo moss balls are unique aquatic plants that act as natural water purifiers in ponds and aquariums.

They help regulate water balance by absorbing and releasing bacteria. This stimulates beneficial bacteria and reduces the growth of unwanted algae.

Marimo acts as a natural filter for fine dust and waste products, providing a healthier habitat for both fish and other pond plants.

Moss balls you can buy at vdvelde. Every aquatic plant comes directly from our own nursery. We pack the moss balls in a special way so that it arrives beautiful and healthy to our customers. Moreover, with us you get a 100% growth and flowering guarantee.

Marimo moss balls are quite flexible in terms of light and temperature. Although they thrive in cool, shady water conditions, they can also survive in various light and temperature levels. However, direct sunlight and excessively hot temperatures should be avoided to maintain optimal health.

Marimo, Chladoflora aegagropila: The soil-purifying oxygen plant

The oxygen plant has been given the name "moss ball," but actually the balls are not composed of moss at all but of green algae. The moss balls live at the bottom of the pond or aquarium where they ensure that the bottom of the water pool is cleaned. The movement of the water slowly rolls the moss ball forward, this way the moss ball can clean up waste products from the bottom.

Moss balls can trap air bubbles due to the movements they make across the bottom of the pond. It can happen that this air bubble makes the moss ball float to the top layer of the pond. When this happens you can take moss ball out of the water and rinse it under the tap, after this you place the moss ball back into the pond water and squeeze it briefly so that all the air leaves the moss ball. Marimo will then sink back to the bottom of the pond by itself.

Not only are they functional in the pond because of their cleansing properties, but their potentially high age also makes them remarkable aquatic plants. Within Japanese tradition, moss balls symbolize good luck, which is why they are often given as gifts, for example in a fine ecosystem.

Care tips for your Marimo moss ball

  • Light and temperature: Although Marimo thrive best in cool, shady waters, they can adapt to a variety of conditions. Avoid direct sunlight and excessively hot temperatures for optimal health.
  • Water Change: Change the water once every two weeks and gently rinse the Marimo under the tap for a fresh and healthy environment.
  • Detect problems: A changing color may indicate a problem. Too much light can cause fading, while brown spots indicate soiling. Black unfortunately means the Marimo is dying, but you can still take action by removing the black pieces.

Moss balls in aquarium

Marimo moss balls are not only decorative in a plant terrarium, but they are also very useful in a pond and in an aquarium as a bottom duster to remove waste products from the bottom to keep the water in the aquarium and pond clear and healthy.

Cladophora

Cladophora, a genus of freshwater and seaweed, is known for its unique properties and versatile uses. This green algae is found worldwide in a variety of aquatic environments, from still lakes to flowing rivers and even in seas. Cladophora is distinguished by its thread-like, woolly structure, which gives underwater landscapes a vibrant texture and density.

Moss ball decoration for home

Marimo moss balls are not only functional in the aquarium or pond for filtering the water, but they are also ideal as a decorative element in the home. For example, you can put the moss balls in a plant terrarium with some water and substrate and then you have a beautiful object for your home that also brings good luck according to Japanese culture!
