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 and convert it into sugar and oxygen in photosynthesis with the help of light.

Easy to install
The system comes completely ready to connect. Screw the pressure reducer onto the CO2 storage cylinder and connect it by hose to the bubble counter (incl. backflow protection) and then 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 the interposed solenoid valve (night switch-off not included). The CO2/pH Permanent Test permanently indicates the amount of CO2 dissolved in the water and can then be readjusted if necessary.

Safe
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 for about 4 months in its default setting.
