CO2 Set – the most important things at a glance
A CO2 set is essential for aquaristics, as it is necessary for plant growth in aquariums. It consists of several components such as the actual CO2 cylinder, a pressure reducer, a diffuser and usually also a bubble counter. The sets differ in the size of the CO2 bottle, which usually varies between 0,5 and 2 L. Another difference is the material of the pressure reducer and the diffuser, which can be made of different metals or plastics. Some sets also include a night shut-off valve that automatically shuts off the CO2 supply during the night. There are also differences in the exact equipment of the sets, so some sets can also contain a CO2 test or special fertilizers.
