The Aquario NEO CO2 Normal Special series is similar to the Normal Original Diffuser in size. The main difference is that diffusers in the Special series lack the built in bubble counter, but does offer a clean low profile appearance that won't take away from the aquascape. Aquario NEO CO2 diffusers are equipped with tiny nanohole that convert CO2 bubbles into a super fine mist, perfect for dispersing and dissolving CO2 throughout the tank.
This Aquario diffuser is acrylic (not easily breakable) with a ceramic disk specially designed to create the finest bubbles.
