The Aquario Neo CO2 diffuser dissolves carbon dioxide into a fine mist of bubbles which allows for better dissolution in your water column. These diffusers have super tiny micro nano holes that make CO2 bubbles disperse in a super fine mist. This super fine mist makes it easier for the CO2 to break down in your aquarium. Super Crucial! Being a part of the Original series, this diffuser keeps the build in bubble counter. The Normal Series are compatible for both rimmed and rimless aquariums, needing tubing to work correctly.

This Aquario diffuser is acrylic (not easily breakable) with a ceramic disk specially designed to create the finest bubbles.

  • Soak it in water for 30 minutes before use to produce smaller bubbles.
  • When bubbles begin getting larger, put it in bleach for 10 minutes and wash with water several times removing all the bleach inside before use.
