Colombo 3 in 1 CO₂ Diffuser - Large

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 300L.
