How many Oxygen Plants in my Pond?
Calculate how many oxygen plants you need using the calculation chart below
It is a shame to have to buy new aquatic plants every year that break down due to persistent frost and therefore can no longer optimally add oxygen to the pond water. Hardy aquatic plants or oxygen plants offer the solution. These aquatic plants are accustomed to low temperatures and retain their oxygen-releasing function. This ensures that the water quality of your pond is optimal even in winter.

Buying oxygen plants?
Why are oxygen plants important for pond balance?
Oxygen plants produce oxygen through photosynthesis, which is essential for fish and beneficial bacteria. They compete with algae for nutrients, reducing algae growth. Without enough oxygen plants, murky water quickly develops and fish can become breathless.
Installation and maintenance of oxygen plants
Oxygen plants work best if they are at the right depth in the water, usually between 40 and 80 centimetres. Dead or decaying parts should be removed regularly to keep the plant healthy and oxygen production up.
Winterising the pond
Allow hardy species such as hornwort or waterweed to overwinter in the pond. Non-hardy species can be placed indoors. Avoid completely freezing the water surface to keep gas exchange possible.
Which species of oxygen plants to choose?
Preferably choose native, fast-growing species such as hornwort, water fringe or glossy pondweed. These plants are effective, robust and adapt well to changing conditions.
Common mistakes with oxygen plants
- Too few plants per litre of water
- Use of pond liner without substrate, making rooting difficult
- Combination with fish species that eat plants (such as koi) without protection
