New from JBL: the CO2  high diffusion reactor with 240 new flow slits

The JBL vario-reactor has undergone a decisive improvement:
the addition of 24 micro-flow slits to each one of the ten reactor modules, ensuring optimum water flow. This means that the CO2 reactor does not need to be placed where the water has strong currents, nor does it require a separate pump to run. Tests conducted by the JBL Research and Development Department have shown the following: it does not matter whether the new JBL high-diffusion reactor is actively provided with current from a pump or is located in a completely current-free zone of the aquarium – the CO2 enrichment of the water remains the same.
This has been made possible thanks to the new micro-flow slits, which virtually create their own reactor current. As the CO2  bubble rises it does not push the carbon dioxide-enriched water ahead of it, as normal, causing a considerable reduction in the solubility of the CO2 gases remaining, but rather is provided with fresh aquarium water every 4 mm through the micro-flow slits, which can absorb far more CO2. This means that the new JBL reactor is far more effective than all previous models.
The collection chamber at the upper end of the new JBL reactor has also been modified. In the event that CO2 bubbles have not completely dissolved on their way through the reactor, they collect in the upper collection chamber. Here the carbon dioxide has time to diffuse in the water. It is well known that gases dissolved in the water diffuse into CO2, with the result that a gas mixture forms in the collection chamber instead of pure CO2. If the volume of gas bubbles exceeds a set amount, they can escape upwards through a special air outlet.
The advantages of the JBL Reactor vario at a glance:

• No separate pump required for operation.
• 240 flow slits provide loss-free CO2 enrichment of the aquarium water and therefore lush plant growth. Due to the micro-flow slits, the reactor can be placed in any position in the aquarium.
• A separate bubble-counter is not required, as the rising CO2-bubbles can be easily and accurately counted in the reactor itself.
• The reactor can be dismantled into 10 modules, making it easy to clean when necessary (to clean the module, simply place in  JBL Power Clean for 12 hours).
• With about 100 cm diffusion length, the reactor is suitable for approx. 350 litres aquarium water. For larger aquariums of up to 1000 litres, the reactor can be extended with additional modules  (each with 50 cm additional diffusion length) within only a few minutes. There is no need to purchase a new reactor.
• Blue-grey plastic keeps the growth of algae inside the reactor to a minimum.
• The reactor is small and handy (only 18 cm high and 43 mm in diameter) and therefore practically unnoticeable in the aquarium. Due to the compact design, it also fits in very shallow aquariums (over 30 cm deep).

Extension options

The bubble path can be extended by inserting any number of extension sets (Art. 63480)

1. Collecting cap to prevent loss of CO2
2. Module (10 x)
3. Base section with hose connection
4. Lid for base section (to prevent water slugs from entering)
5. Retaining clip with suction pad
6. Connecting hose

1. First rinse the entire unit thoroughly in warm tap water. Do not use cleaning agents!
2. Install CO2 vario upright at a point in the aquarium with moderate water movement, with the top edge of the unit immersed at least 2 cm below the surface of the water.
3. Link connecting hose to CO2 fitting and first allow only a few bubbles to flow through the unit.
4. When using the unit for the first time, the bubbles will rise slowly up from the bottom to the top through the spiral bubble path. The unit requires a running-in time of approx. 48 hours. The biological film forming after that allows the bubbles to rise unobstructed. On their way to the top the bubbles grow smaller, indicating that the CO2 diffuses into the surrounding water. Once they reach the top, the bubbles pass into the collecting cap where any remaining CO2 residues are diffused completely.

Note: After a certain time the collecting cap will fill with gas which will occasionally escape upwards through the ventilation slots on the side. This gas is not CO2 , but what is known as false gas which is found in small quantities in the actual CO2 bottle and which also diffuses into the bubbles as they rise through the surrounding water. Clean the CO2 vario as rarely as possible. It is therefore advisable to attach the unit at a fairly dark and unlit point in the aquarium with adequate water movement.
To guarantee optimum diffusion, make sure that the slots between the modular sections are not blocked by plant segments or decorative objects.
