Chihiros Nano CO2 diffuusori (L)

The porous ceramic membrane creates a fine CO₂ mist with a large total contact area. Positioning the diffuser low in the aquarium near the filter outflow allows the water circulation to distribute the bubbles throughout the planted layout.

The L model provides the largest ceramic surface in the Chihiros Nano CO₂ Diffuser range and is intended for aquariums with greater carbon-dioxide demand.
