Dymax CO2 40cm Diffuser (36mm Diameter) – Stainless Steel CO2 Diffuser for Planted Aquariums

The Dymax CO2 40cm Stainless Steel Diffuser delivers excellent CO2 diffusion for planted aquariums. Its quartz ceramic disc produces ultra-fine bubbles, increasing the surface area and ensuring maximum absorption of CO2 into the water.

Designed for easy installation and maintenance, the ceramic disc is simple to replace when needed. The high-quality stainless steel body resists rust while adding a sleek, modern look to your tank. Running this alongside a regulator? Our Dymax CO2 Mini Regulator is a compatible pairing, and our Dymax Aluminium CO2 Bubble Counter is a handy way to visually track your dosing.
