The AQUARIO NEO CO2 Diffusor Extended Special Type is an acrylic CO2 Diffusor with an extra long pipe which can be individualized very easily by a special heat technique. Dangling around hoses disappear from your aquarium tank's surrounding and your whole aquarium setup looks organized and tidier than before.

Example Layout

The special ceramic membrane produces a fine mist and the CO2 gets dissolved very quickly. The diffusor itself is very narrow and connects to the pipe at its side.

Inside the package you will find two extra pipes of 16cm length which you may use to try this innovative technique before using the actual product. By heating up the pipe the acrylic material becomes flexible. It can then be adjusted to any form you need in your aquarium. Here, you will find a simple summary.


Aquaio Neo CO2 Diffurosren Extended Type - The heat technique

  • Insert the enclosed rubber strip into the acrylic pipe.
  • Heat the pipe with a lighter while rotating at a distance of 1-3 cm.
  • As soon as the acrylic material is softend it can be curved.
  • The beforehand inserted rubber strip minimizes the chance of reducing the inner diameter of the pipe. It can now be removed.
  • For finest bubbles it is advisable to put the diffusor into water for 10 minutes, so that all membrane pores get soked completely.
  • If the bubbles get bigger with time, you can clean the membrane with bleach. You will find a detailed describtion below.

Before use, immerse the diffuser in water for 10 minutes so that all the air in the diffuser is displaced. If there is still air in the diffuser, larger bubbles may form at the bottom of the diffuser ceramic.

Tips for application:

  • If the flame is too close to the pipe it will get black from soot. Please keep the distance named above.
  • If the pipe is not rotated while heating, the bend will appear unattractive and have overlapping material inside the curve.
  • As soon as the material is softened, it is advisable to act firm and quickly to prevent the material from cooling while adjusting.
  • When aiming at a 180° curve, it is best to move the flame back and forth for a while in order to get a larger soft acrylic area.
  • If you want to bend the pipe around your aquarium tank's wall, you do not necessarily need two bends. Just make use of a 180° curve and hold both pipe ends very tightly to the wall. The 180° will slowly expand adequadly.
