Any aquarist who feeds his plants with carbon dioxide (CO2), because he doesn’t want them to starve, has to regulate the CO2 gas supply. Here a bubble counter is required to make the CO2 gas visible in the water, enabling the number of bubbles per minute to be counted. Only then can the number of bubbles be precisely increased or reduced by adjusting the CO2 unit.
The new JBL bubble counter doesn’t only provide the opportunity to accurately count the CO2 bubbles you add, it also contains a check valve, which safely prevents the backflow of the water to the CO2 unit. The modern, small, white JBL ProFlora Count safe thus combines two useful and necessary devices in one.
