This CO2 regulator splitter for planted aquarium tanks allows the user to inject CO2 into multiple planted aquarium tanks through a sole cylinder. With up to a 6-way split, one CO2 cylinder can be used to supply each planted aquarium tank, cutting down on cost while remaining efficient and ensuring aquatic plants are receiving essential CO2. Easy to install and built from quality stainless steel, this CO2 regulator splitter doesn't require any tools aside from a strong wrench arm and provides lasting rust-free durability. 

Why CO2 injection is important in a planted aquarium tank: 
3 main factors contribute to the optimal growth of aquatic plants. These factors include nutrients, light and carbon dioxide (CO2). If any of these are unbalanced, the results are algae growth or the withering of aquatic plants. The introduction of CO2 in a planted aquarium tank allows aquatic plants to thrive and grow more efficiently, while also giving them the ability to outcompete algae for nutrients.
