• Supplies aquarium plants with their main nutrient CO2, for healthy & vigorous growth while preventing algae
• Easy to assemble: mix the bio-components with water in the reaction canister, connect the hose with the backflow protection and the reactor. Place the reaction canister in the thermal casing – done
• Natural: CO2 production through biological fermentation process. Economical: 2x40 days of unwavering CO2 production through an immediate and long-term buffer system. Bio-components can be purchased individually for refilling
• No CO2 pressurised cylinder necessary. The system works exclusively via a biological process in a high-quality, transparent reaction canister
• Packaging contents: ready-to-connect Bio-CO2 fertiliser system, incl. reaction canister, thermal casing, 2x bio-components, 3 m special CO2 hose, suction holder, backflow protection, expandable reactor.

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 germs. The 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.

The difference between Bio-CO2 and pressurised gas cylinder CO2 systems:
Bio-CO2 systems are based on the biological process of yeast fermentation in which CO2 is produced. Here 2 bio-components are made to react in a bottle/reaction vessel. To replenish the system after about 40 days, the reaction bottle/vessel only needs to be refilled with water and the two bio-components.
In the CO2 pressurised gas cylinder system, the CO2 gas is present at about 60 bar in steel pressure cylinders. When they are empty, they can be refilled by a specialist retailer (reusable cylinders, M system) or they are disposable cylinders (U system) which are simply replaced.

It makes no difference to the plants where the CO2 comes from, whether it is from biological or pressurised cylinder systems. They grow much stronger as soon as a CO2 system is installed. The systems are of more concern to the aquarists, who have to decide whether they want disposable cylinders, refillable pressure cylinders or a pressureless bio system.

In addition to CO2 fertilisation, it is important you don’t neglect the other components that are necessary for healthy & vigorous growth of the aquarium plants: the right light (e.g. JBL LED SOLAR); sufficient fertilisation with minerals & trace elements (JBL PROFLORA FERROPOL); preferably a root fertilisation for strongly rooting plants with JBL PROFLORA FERROPOL ROOT/ The 7 Balls; the right water temperature (usually between 23 and 26 °C); and the absence of plant-eating fish.
