CO2 fertilization kit ready to connect for an optimal intake to all freshwater aquarium plants from 40 to 300 L, thus preventing algae.
Easy assembly: Screw the regulator on the bottle, connect the hose in the bubble account/flash valve and diffuser. Configure the number of bubbles - finished.
Rechargeable CO2 bottle approved Tüv. No sliding of the hose thanks to the screwed pipe fittings, anti -road valve preventing water penetration into the bottle.
The correct concentration of CO2 in the water of the aquarium is controlled on the display of the CO2/PH permanent test provided and can be, if necessary, readjusted.
Contents: 500 g bottle of rechargeable CO2 with wall fixing, regulator, 3 m of pipe, bubble account with anti-road valve, ceramic diffuser, permanent test with reagents, 2 100 ml fertilizers, 1 daily fertilizer.
Nutrition of plants
Plants provide the aquarium oxygen, which is of vital importance for its occupants, they warn the appearance of algae and eliminate problematic substances. The JBL fertilization system brings CO2 plants to their main nutrients, through water. The plants absorb it and, using light, transform it into sugar and oxygen during photosynthesis.

Easy installation
The system is fully ready to connect. Screw the regulator on the CO2 bottle and connect it by the pipe with the bubble account (including the anti-return valve), then with the diffuser in the aquarium. CO2 thus arrives in the aquarium and dissolves in water using the diffuser. The contribution of CO2 can be interrupted at night by a solenoid valve mounted as an intermediary (night cut: not supplied). The permanent CO2/pH test continuously displays the amount of CO2 dissolved in water which can, if necessary, be readjusted.

Security
The bottle is approved (Tüv). Thanks to the anti -return valve, the water cannot enter the bottle. The autonomy of a CO₂ system depends on several factors. The essential elements are carbonated hardness, the quantity and type of plants as well as the power of the water movement on the surface. A bottle of 500 g which is not interrupted at night by a solenoid valve lasts about 4 months with the basic adjustment. Multiple bottles can be recharged from specialized merchants.

Conversion of disposable bottles to rechargeable bottles and vice versa: all C2 JBL bottle systems are compatible with each other. In the rechargeable system (M system), just unscrew the regulator's-rail-rail nut using an Allen key. The regulator is then adapted to the U system (single -use bottles).
