Ista CO2 3-in-1 Vertical Diffuser with Bubble Counter and Check Valve

The Ista CO2 3-in-1 Vertical Diffuser is a CO2 diffuser for planted aquariums that combines a ceramic diffuser, bubble counter, and check valve in one unit. It is designed for aquarists who want to deliver CO2 evenly to aquatic plants.

Its high-quality ceramic diffuser and suction cups help produce fine, even diffusion, and its connectors are designed to help keep hoses from kinking. It works as both a bubble counter and a diffuser, and can be used inside or outside the aquarium.
