CO2 in aquaristics

  • CO2 is the most important nutrient for plants in the aquarium. Through photosynthesis, plants absorb CO2 and produce oxygen, which is crucial for a healthy biotope in the aquarium.
  • The addition of CO2 promotes plant growth and allows plants to grow healthier and stronger. Together with balanced fertilisation, algae growth is also reduced as the plants can compete better.
  • There are various methods for adding CO2 to an aquarium in a targeted manner. For example, using CO2 fertiliser systems or special CO2 cylinders. However, the dosage should be carefully controlled in order to avoid an excess of CO2.
  • A balanced ratio of CO2, light and nutrients is crucial for healthy plant growth in the aquarium. It is therefore important to regularly monitor the CO2 content in the water and adjust it if necessary.
  • The addition of CO2 can not only promote plant growth, but also help to adjust and stabilise the pH value in the aquarium. A stable pH value is important for the well-being of the fish and other creatures in the aquarium.
  • In aquaristics, CO2 plays an important role in the health of the plants and the creation of a stable ecosystem in the aquarium. A targeted addition and monitoring of the CO2 content enables aquarists to create an optimal environment for their plants and fish.
