Tropica CO2 Diffuser 3-in-1

SKU: T245

The Tropica CO2 Diffuser 3-in-1 is an innovative solution for tropical freshwater fish tanks. This all-in-one unit combines a bubble counter, reflux valve, and ceramic diffuser. The bubble counter allows easy and precise CO2 dosage, enhancing adjustment accuracy. A reflux valve prevents water from being sucked backward, ensuring continuous functionality. The custom ceramic disc generates microbubbles, increasing CO2 utilization over regular air stones. The transparent acrylic pipe facilitates bubble counting, while the ceramic disc ensures efficient CO2 diffusion mist. Elevate your aquarium with Tropica's CO2 Diffuser 3-in-1 for optimal plant growth in your tropical freshwater fish tank.

Tropica CO2 Diffuser 3-in-1


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.
