Chihiros Nano CO2 Diffuser

Diffuser allows effective and maxiumal CO2 injection into an aquarium. The CO2 is pushed through a porous medium that breaks down the gas into a fine mist of bubbles. These bubbles are then more easily absorbed by aquarium water.

In natural environments which have thriving plant growth, there are organic decomposition and underground stores of CO2 that have 10-40+ ppm level of CO2. However, there is only 2-3ppm of dissolved CO2 in an aquarium tank because CO2 diffusion in water is 10000 times slower compared to in air. As such, injection of CO2 (gaseous or liquid form) in the planted aquarium has become a common practice amongst aquarists.

When optimally provided, CO2 enables plants to thrive in form, colour, density and health. On other hand, poor provision of CO2 causes plants to suffer from stunted growth, paling in the leaves and stems, and algae growth.
