Product information

Ideal nutrition for plants
The right CO2 concentration in the water is of great importance for the aquarium plants. Carbon dioxide is the main nutrient for plants and promotes their growth. Plants use the CO2 for the photosynthesis and thus supply the water with essential oxygen. They prevent algae growth, remove pollutants, provide hiding places and reduce pathogens.

Economical and direct
This practical CO2 direct diffuser saves a diffuser in the aquarium, a bubble counter and a check valve. It even saves 20 % CO2 thanks to its ingenious functioning. All that is needed is an external filter with a suitable hose connection.

Easy to install
In order to ensure that the CO2 gas passes as far along the inside of the hose as possible, the direct diffuser needs to be integrated into the hose as close as possible to the external filter. A vertical mounting position will ensure the best readability of the bubble counter.

FAQ
How can I remove the hose from the device?

At first the air hoses and special CO2 hoses can easily be pushed on the connection piece. The hoses harden more and more as the months go on and can only be removed from the connection piece using great force. If you pull the hose hard it will only strain the connection, which could, in the worst case, even break off. Instead cut the hoses you want to remove laterally at the ends and carefully remove them. For this it’s always advisable to install hoses with some reserve in its hose length.

What working pressure does the ProFlora direct need?

We recommend a working pressure of 1.0 – 1.5 bar.

Can the inline diffuser be used in a bio-CO2 system?

We wouldn’t recommend installing the JBL ProFlora Direct in a bio-CO2 system. The working pressure is not big enough to achieve an even addition of the CO2. Moreover, there is a danger that the pressure will not be able to escape through the integrated check valve, and this can lead to damage in the reaction vessel, if it isn’t able to withstand the pressure.

Is my SafeStop damaged if I can’t blow through it?

The retaining spring in the check valve fits very tightly and ensures that no water can return. Therefore the air pressure of a diaphragm pump or our breath is not strong enough to open the spring. The valve can be opened by the pressure of the ProFlora bioCO2 systems and also the m and u series. Check valves used in air systems have a smaller counter-pressure and are also part of the JBL range.

I can hear the ProFlora direct whistling / chirping

In this CO2 diffuser the CO2 gets pressed through a fine diaphragm. Depending on the counter-pressure, this sometimes causes a slight chirping sound. If the sound intensifies during operation this indicates a soiling of the diaphragm or change in the operating pressure. Please clean the diaphragm and reduce the operating pressure, if required.
