Ideal nutrition for plants
Having the right CO2 concentration in the water is hugely important for aquarium plants. Carbon dioxide is the plants’ main nutrient and it fully promotes their growth. Plants use CO2 for photosynthesis and this supplies the water with essential oxygen. They prevent algae growth, remove pollutants, provide hiding places and reduce germs.
Efficient enrichment of the aquarium water with CO2:
The CO2 gas enters the lowest module through the CO2 supply hose in the middle of the reactor. There it enters the bends of the CO2 reactor in bubbles (visible and thus countable) and rises upwards in a circle, like in a car park driveway. On this long path, the CO2 dissolves from the CO2 bubbles in the aquarium water. In this way, the CO2 system supplies the aquarium plants with their main nutrient, carbon dioxide.
Why don’t the CO2 bubbles dissolve completely?
On their way up, the bubbles release CO2 into the aquarium water, but at the same time absorb other gases from the water, because these gases are more concentrated in the aquarium water than in a CO2 bubble. Therefore, the CO2 content in the bubble decreases and, for example, the oxygen and nitrogen gas content increases. At the end of its journey through the CO2 reactor, it has clearly become less, but it only contains as much CO2 as the surrounding water and all the gases that are also contained in the aquarium water.
If the desired CO2 content is not achieved even though the bubble count has been increased, the reactor can be extended by adding further modules. This extends the path for the CO2 bubbles and more CO2 can be added. The only limitation is the height of the aquarium.
