CO2 Diffusers for Aquariums

Freshwater aquarium plants need CO2. An aquarium CO2 diffuser sits at the end of the CO2 system, and can come in many styles, such as an inline CO2 diffuser that connects to an inlet pipe, or a glass CO2 diffuser that sits in the aquarium. A CO2 diffuser's converts incoming CO2 gas into micro bubbles, which increases water contact to efficiently raise aquarium CO2 levels. Otherwise, large CO2 bubbles would rise to the surface, pop, and release CO2 into the air.
