Everything to do with CO₂ in the aquarium shop - large selection of CO₂ products for your aquarium


CO₂ is the elixir of life for healthy and vigorously growing aquarium plants. Without a sufficient supply of carbon dioxide, plants can only photosynthesise to a limited extent - growth stagnates, algae spreads and the natural balance in the aquarium is upset. With the right CO₂ supply, you not only promote the vitality of your aquatic plants, but also oxygen production and the general well-being of your fish.


Why CO₂ is so important in the aquarium

Aquarium plants need CO₂, light and nutrients in order to photosynthesise. However, tap water usually contains very little CO₂ - too little for densely planted or heavily lit aquariums. Targeted CO₂ fertilisation therefore ensures lush green leaves, more intense colours and a stable biological balance. 


CO₂ systems and accessories

In our range you will find complete CO₂ systems, refill bottles, pressure reducers, diffusers, non-return valves and other accessories from leading brands. Whether you are a beginner or a professional - we offer the right solution for every aquarium: from organic CO₂ systems for small tanks to precise pressurised gas systems for sophisticated aquascapes.


CO₂ fertiliser and supplementary products

In addition to CO₂ systems, we also offer liquid CO₂ fertilisers and combined plant nutrients that optimally supply your aquarium plants with carbon and trace elements. These products are ideal as a supplement or alternative to technical systems - especially for smaller or medium-sized aquariums.
