The Colombo diffuser is a neat, self contained piece of kit that combines style, function and affordability. In a nutshell, a bubble counter, non return valve and ceramic diffuser in one.

The customised ceramic disc, ensures the efficient creation of micro bubbles, which makes your gas go further.

How to use the product:

Colombo’s CO2 diffuser contains a bubble counter, non return valve and diffuser in just one unit. The bubble counter enables easy and accurate CO2 dosage, since it is easy to count the big bubbles inside the chamber during adjustment. A non return valve prevents the aquarium water from being sucked backwards, which is possible when the bottle gets empty, or in case you use a magnet valve to turn off the CO2 supply during the night.

TIP: in order to ensure perfect adherence to the glass, make sure that the glass is clean and grease-free; apply an ultra-thin layer of Vaseline on the suction pads to ensure adherence.

This diffuser is suitable for tanks up to 150L.

Great diffuser, my favourite one so far. I like that the non-return valve and bubble counter are built in as it means there are less joins in the tco2 tubing so less risk of leakage, also it looks neater. Produces a fine mist of bubbles. I recommend it.
