The UNS Micro CO2 Regulator Kit includes the regulator, solenoid and bubble counter conveniently packed into one box. All items work together seamlessly to provide planted aquariums with a reliable and efficient CO2 system. Pair the kit with a disposable co2 cartridge for a full nano freshwater planted tank CO2 setup. A great space saving solution for hobbyists that's effective and simple to use.
There are two basic requirements for plants to grow through photosynthesis; nutrients and light. The most important nutrient for plant growth is carbon. Since carbon dioxide (CO2) is abundant in the atmosphere, plants simply draw their carbon directly from CO2 in order to photosynthesize and grow. In an aquarium, CO2 levels are naturally very low and without any supplementation, submerged aquatic plants will not be able to grow properly. When CO2 is a limiting factor, plants cannot fully utilize all the available light to photosynthesis. This can allow algae to grow and compete with the plants for nutrients, further stunting plant growth. By introducing CO2 into the aquarium, plants can achieve healthy growth faster and therefore outcompete algae.
