Dennerle CO2 Adapter - Reusable DRM for Disposable Bottle

So that the plants in your aquarium show beautiful colours and grow together well, they depend on various factors to enable their photosynthesis. In addition to good lighting, they also need a nutrient-rich substrate and a carbon source. Some plants get their nutrients from the leaves, others also from the roots. The perfect combination of the necessary factors allows you to turn your aquarium into an eye-catcher with magnificent plant growth and breathtaking colours. The correct amount of CO2 in the water is of the utmost importance for aquarium plants. Carbon dioxide serves as a nutrient for the plants and only in this way enables their full development. Plants need CO2 for photosynthesis, in which they produce oxygen, which they release into the aquarium water. Good plant growth also prevents algae growth, removes pollutants and offers the animals retreat. Algae growth is inhibited because optimally supplied plants deprive the algae of their food base.

With the CO2 adapter, you can combine the pressure reducer with all commercially available 500g reusable bottles, and thus create a larger stock.

Tip: If you really want to get the most out of your plant aquarium, combine the CO2 fertilisation with the plant elixir and the NutriBalls!
