• Provides aquarium plants with CO2, their main nutrient, for vigorous and healthy growth while preventing algae.
• Very easy assembly: mix the bio-components with water in the reaction bottle, connect the tube to the diffuser – done.
• Natural: CO2 produced through a biological fermentation process. Economical: 40 days of consistent CO2 production thanks to an immediate and long-lasting buffer system. Bio-components can be purchased individually as refills.
• No need for a pressurized CO2 cylinder. The system operates solely through a biological process.
• Contents: Ready-to-connect CO2 bio-fertilization system, with reaction bottle, bio-components, 3 m of special CO2 tubing, suction cup, diffuser.

Aquarium Plant Nutrition:
Plants provide the aquarium with oxygen, which is vital for its inhabitants. They prevent algae growth and eliminate harmful substances. The JBL fertilization system delivers CO2, their primary nutrient, to the plants via the water. The plants absorb it and, with the help of light, convert it into sugars and oxygen through photosynthesis.

Difference between bio-CO2 systems and CO2 cylinders: Bio-CO2 kits are based on a biological yeast fermentation process that produces CO2. Two biological components react in a reaction tank.
To replenish the system after approximately 40 days, simply refill the reaction tank with water and the two components. In CO2 kits with cylinders, the CO2 gas in the cylinders is pressurized to approximately 60 bar. Once empty, the cylinders can be refilled (refillable cylinders, System M) or, if they are single-use cylinders (System U), replaced.

Plants don't care at all about the source of the CO2, whether it comes from a biological system or a cylinder. They grow significantly better once a CO2 system is installed. These systems are quite important for aquarists. Do they want disposable or refillable cylinders, or a pressure-free biological system?

In addition to CO2 fertilization, it is also important to pay attention to the other components necessary for healthy growth of aquarium plants: good light (e.g. JBL LED SOLAR), sufficient fertilization of minerals and trace elements (JBL PROFLORA FERROPOL), ideally root fertilization in case of significant root development with JBL PROFLORA FERROPOL ROOT / The 7 pellets, the right water temperature (between 23 and 26 °C) and no plant-eating fish.
