Product information

Nutrition for aquarium plants
Plants provide the aquarium with vital oxygen for your aquarium inhabitants, prevent algae growth, remove pollutants, provide hiding places and reduce pathogens. The JBL plant fertiliser system supplies the plants with the main nutrient CO2 through the water. The plants absorb this through their leaves.

Easy to install
The system comes completely ready for connection. Screw the pressure reducer onto the CO2 storage cylinder. Connect the pressure reducer with the hose to the diffuser in the aquarium. CO2 thus enters the aquarium and is dissolved in the water with the help of the diffuser. The CO2 supply can be interrupted at night by an interposed solenoid valve (not included).

Safe
The storage cylinder is equipped with an overpressure relief. A check valve means no water can enter the cylinder. The capacity of a CO2 system depends on several factors. The carbonate hardness, the quantity and species of the plants and the strength of the water surface movement are decisive. In its default adjustment a 500 g cylinder not switched off by a solenoid valve during the night lasts for about 4 months.

FAQ
Can the 1200g disposable cylinder also be used with the older JBL CO2 systems?

Yes, this is possible without any problems. The JBL PROFLORA CO2 CYLINDER 1200 U also fits the older pressure reducers of the JBL PROFLORA u range.

Can you operate JBL ProFlora CO2 cylinders (disposable & reusable system) horizontally?

No, because this can lead to the destruction of your pressure reducer. To ensure safe operation, all storage cylinders should only be operated upright. Never operate them in a lying position or upside down.

What do I need the enclosed Allen key for?

You need the enclosed Allen key for the conversion if you want to adapt your ProFlora u system onto the refillable cylinder of the m series. The ProFlora Adapt u-m is to be mounted as adapter.

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.

How do I know that my CO2 pressure gas cylinder still has gas in it?

The cylinder pressure of 50 – 60 bar, depending on the room temperature, remains constant until the cylinder is almost completely empty.
You can read the tare weight on label of the u500 CO2 cylinder. According to this a full u500 CO2 cylinder weighs 1140 g tare + 500 g filling.

Super Co2-Anlage, um in die CO2-Düngung günstig einzusteigen. Es ist alles dabei und sollte man mal später auf eine Mehrweg-Flasche umsteigen wollen, ist das auch mit entsprechenden Adaptern kein Problem – siehe dazu auch: https://co2-anlage-aquarium.de/co2-flaschen-adapter/

Co2 Anlage ist bei mir im 60 Liter Becken im Einsatz.

Keine Mängel vorhanden. CO2 Anlage läuft sehr gut. Die Qualität stimmt auch!

Generell ist eine CO2 Anlage zu empfehlen. Seid ich diese CO2 Anlage im Einsatz habe sind meine Pflanzen schneller gewachsen.
