Product information

Nutrition for aquarium plants
Plants provide the aquarium with vital oxygen for the aquarium dwellers, 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. They 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. The CO2 enters the aquarium and is dissolved in the water by the diffuser. The CO2 supply can be interrupted at night by adding a solenoid valve.

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

Technical Data

FAQ
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.

Bluish discolouration despite increased CO2 supply

Owing to a production fault a green colour change may not occur with the batches 1000 and 1001, despite increased CO2 supply.

Should you have one of the above mentioned batches, you can request a new refill set free of charge upon presentation of the sales receipt and a photo of the batch number. Please contact our customer service under: https://www.jbl.de/support/

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.
