Tropica CO2 Diffuser 3-in-1

• Bubble counter, check valve and ceramic diffuser in one
• Specially developed ceramic plate that ensures effective formation of microbubbles
• Improves the utilization of carbon dioxide many times over compared to a normal air stone

The Tropica CO2 diffuser combines a bubble counter, check valve and diffuser in a single unit. The bubble counter allows for easy and accurate dosing of CO2 as the large bubbles in the chamber are easy to count when adjusting. A check valve ensures that water from the aquarium is not sucked back into the hose, which can happen if the bottle runs dry or if you are using a solenoid valve to shut off the CO2 supply at night.

TIP: For perfect adhesion to the glass, the panes must be clean and free of grease. If necessary, apply a very thin film of Vaseline to the suction cups so that they adhere securely.
