This CO2 diffuser dissolves carbon dioxide into a fine mist of bubbles which allows for better dissolution in your water column. Twinstar's CO2 diffuser credits itself as a diffuser that will last longer than most glass diffusers. 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.  

What else do you need to get to supply CO2 to your aquarium?

Micro Holes

The Twinstar CO2 Diffuser has super tiny micro-holes that makes CO2 bubbles disperse in a super fine mist that is suitable for aquarium plants. This super-fine mist makes it easier for the CO2 to break down in your aquarium. Very crucial!
