LANDEN AERVITA CO2 Diffuser Kits is a professional aquarium CO2 dissolver, which is made of high-quality acrylic and nano-sized ceramic diffuser sheet materials, which can dissolve carbon dioxide into fine mist bubbles, thus realizing the efficient dissolution of CO2 in the aquarium. The delicate and translucent acrylic refining tube blends with the aquarium environment to create a harmonious and unified feeling. It is also hard-wearing and unbreakable, lasting longer than most glass diffusers. With complete but streamlined accessories, you can use it without installing the tubes inside the aquarium.
