The Aquario NEO CO2 diffuser dissolves carbon dioxide into a fine mist of bubbles which allows for better dissolution in your water column. Aquario’s NEO CO2 Diffuser credits itself as a diffuser that will last longer than most glass diffusers. The NEO CO2 Diffuser Acrylic allows for a cleaner look. The best part? It’s made of acrylic so it won’t break easily! We’ve tested this product ourselves by throwing it on the floor and they don’t break.
