Product description

The CO2 production system of JBL BioCO2 100 is designed for the average temperature of living rooms of 20 - 25°C. If the temperature is permanently below 21°C, CO2 production may be reduced. In such an event, the amount of micro-organisms should be increased by 1 - 2 spoonfuls. As the temperature of the living room drops at night, so the production of CO2 , which is not needed by plants at night, also correspondingly falls. The intensity of CO2 production can be regulated by the amount of micro-organisms. More micro-organisms increase the quantity of CO2 produced each day and reduce the period of use and vice versa. For cases of low carbonate hardness (below 7° G) combined with more micro-organisms than given in the table above, we recommend monitoring with the JBL Test Set Permanent CO2 plus pH. The surface of the water should only move slightly to avoid unnecessary CO2 loss: position the filter inlet approx. 3 - 5 cm below the surface of the water.

The reaction flask with nutrient mixture (component 1) and the micro-organisms (component 2) can be purchased separately as needed. One pack of micro-organisms is sufficient for several applications (reaction flasks) and should be stored in a refrigerator after opening. The reaction flask (suitable for both JBL BioCO2 100 systems) should be replaced by a new one after the CO2 formation is exhausted. The liquid in the flask may be safely disposed of into the waste water / sewage system.

The CO2 vario is comprised of grey-coloured makrolon which helps prevent algae growth in the bubble channel. If required, the unit may be cleaned in clean tap water. To clean the unit, simply dismantle into its individual sections by pulling the sections apart in an upright position. After cleaning, simply re-assemble the unit. The modular sections slot together. Check that they are correctly interlocked to make an uninterrupted bubble channel.
The CO2 vario is suitable for universal use. If you should wish at some time to change to a professional CO2 system from the JBL PROFLORA range, the vario can still be used. The vario can be extended to any length with extension sets, making it suitable for almost any size of aquarium. Your specialist retailer will be pleased to give you further information.

First rinse the entire unit thoroughly in warm tap water. Do not use cleaning agents.
Install the CO2 vario upright at a place in the aquarium with moderate water movement. The top edge of the unit should be at least 2 cm below the surface of the water.
At first the bubbles will only rise slowly from the bottom to the top through the spiral bubble channel. The unit requires a running-in time of approx. 48 hours. The biological film which forms in this time allows the bubbles to rise unobstructed. On their way to the top the bubbles become smaller, indicating that the CO2 is diffusing into the surrounding water. Once at the top, the bubbles pass into the collecting cap where any remaining CO2 residue is completely diffused.

After a certain time the collecting cap will fill with gas which will occasionally escape upwards through the ventilation slots in the side. This gas is not CO2 , but what is known as false gas which diffuses from the surrounding water into the bubbles as they rise.

In order to maintain optimum diffusion, ensure that the slits between the modular sections are obstructed as little as possible by parts of plants or decorative objects.

Unscrew the snap-top lid of the reaction flask and fill the flask to the upper edge of the label with tap water (not aquarium water) at a temperature of approx. 20°C.

Add the required amount of micro-organisms using the dosage spoon enclosed (broad end of the double spoon). The number of dosage spoonfuls is given in the following table:

**Number of dosage spoonfuls depending on aquarium size and CH**
	50 l / 60 cm	100 - 120 l /80 cm
Below 7° GCH	2	4
Over 7° GCH	3	5

Screw the snap-top firmly back onto the flask and shake briefly.
Connect the CO2 vario unit as described below.
Place the flask close to the aquarium and connect the hose of the vario system to the opening on the snap-top lid. CO2 production will commence within 12 hours and is recognisable by the formation of bubbles on the wall of the flask. The initial blue colouring of the solution disappears in approx. 8 days.

Note:

Reaction flasks must be placed out of the reach of children, in a position where the flask cannot topple over or be knocked over.
Nutrient which accidentally leaks into the aquarium may lead to a drastic lack of oxygen!
In such an event, sufficient water should be changed immediately.

JBL BioCO2 100 vario is the combination of the popular JBL BioCO2 100 and the professional vario diffusion system for loss-free, visible CO2 diffusion in the aquarium. CO2 is the main nutrient which plants require in the aquarium to grow healthily and provide fish with sufficient vital oxygen. Over a period of approx. 45 days, JBL BioCO2 100 vario produces 50 litres (=100g) CO2 by biological methods using the activity of harmless micro-organisms. The system is simple, easy to use and does not require any compressed gas bottles. In conjunction with the vario system and with the amount of CO2 produced, plants in aquariums of up to 100 l can be supplied with sufficient CO2 .

Contains 5 diffusor modules for the effective and loss-free CO2 enrichment of aquarium water.
Supplies aquariums holding up to some 120 litres, with CO2 over about 45 days.
No compressed gas bottle.
Each component is available individually.
The vario diffusor of the system does not require a separate pump!
