CO2 Set Aquarium – the most important things at a glance
A CO2 set for aquariums is an essential accessory for any aquarist who wants to promote plant growth in their aquarium, as plants need CO2 for their photosynthesis. There are different types of CO2 kits that vary in functionality and price. Beginner sets are often easy to use and usually include a disposable CO2 bottle, a pressure reducer and a diffuser for optimal distribution of the CO2 in the water. Professional sets can additionally have a length regulator, a night shut-off or a bubble counter. The size of the set should be adapted to the volume of the aquarium to ensure the optimal level of CO2 in the water. It is important to find out about the technical details before buying in order to find the right set for the individual needs of the aquarium.
