The Aquario NEO CO2 Extended Original series is the extended version of the Normal Original series. The tube length has been increased to remove the need for airline tubing being inside the tank. The Extended Original keeps the built in bubble counter design of the Original series. Users will also have more flexibility to choose where the diffuser will be placed and where to bend the tube. 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.

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