The Fischer brand  Nano Long Glass CO2 Diffuser is a fuse of quality and affordability; ensuring that you get an excellent quality glassware component, at an affordable price. Designed for use with a pressurised CO2 system, this CO2 diffuser ensures that your CO2 is efficiently dissolved into your aquarium water through the use of a 1.7cm ceramic disc mounted inside the diffuser. It is ideal for growing healthy plants in a nature aquarium, where a stable and sufficient CO2 level is essential.

The hand crafted, high quality glasswork ensures that it looks the part in even the highest quality nature aquarium, whether it be on display at the front of the tank or, thanks to the transparent properties of glass, hidden away at the back. Each glass diffuser is hand made and unique - varying ever so slightly in shape and appearance. At 1.5cm tall, 2cm wide and 3.25cm deep, this CO2 diffuser is recommended for aquariums up to 180 litres, although it can be used in higher volume aquariums if the water flow and positioning are adequate.


To use, simply connect the CO2 diffuser to your CO2 regulator using Fischer  CO2 Tubing. We recommend that you heat the end of tubing in hot water, before attaching it to the glassware, as this will help prevent any accidental breakages. Using the supplied suction cup(s), place the diffuser in the front corner of your aquarium. The ideal placement varies depending on water flow, aquarium size and a variety of other factors; but this is a good position to begin with. Set the regulator working pressure to around 1 bar and wait for sufficient pressure to build up and begin forcing CO2 through the ceramic disc. If this doesn't happen within 30 minutes, gradually increase the working pressure until it does. Ideally, the small bubbles that the diffuser produce should spread evenly around the whole tank, ensuring a uniform spread of CO2. A completely sealed yeast system should be able build up the required pressure, however we cannot guarantee that it will definitely work due to the many variables involved in DIY systems. If you are using this diffuser on a DIY CO2 setup, please allow up to 48 hours for sufficient pressure to build up.
