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.
