The CO2 Diffuser offered by Tropica is a versatile, 3-in-1 tool which is ideal for use in any aquarium set up which utilizes a CO2 system. Functioning as a bubble counter, reflux valve, and ceramic diffuser, it will prove to be a useful addition, making the observation and maintenance of your CO2 injection system easier.

2-10 Days

Tropica’s CO2 diffuser contains a bubble counter, reflux 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 reflux 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.



The bubble counter feature allows you to monitor the dosage of CO2 being provided to your aquarium, while the reflux valve prevents the back flow of water during the event of a power outage, or when your CO2 cartridge has depleted. Employing a customized ceramic disc, the diffuser ensures that an efficient amount of micro-bubbles are being produced, allowing the appropriate dispersal of CO2.
