CO2 fertiliser system complete set with 2 pressure gauges, night switch-off and diposable cylinder for vigorous and beautiful aquarium plants Ready-to-connect CO2 fertiliser system with solenoid valve for night switch-off. Provides the ideal supply for all aquarium plants in freshwater aquariums from 40 to 600 l while preventing algae Simple assembly: screw the pressure reducer with its mounted solenoid valve onto the cylinder, connect the hose with the bubble counter/check valve and reactor. Plug the solenoid valve into the timer (not included), set the bubble count - done Refillable storage cylinder TÜV-tested. No hose slippage thanks to hose screw connections, check valve prevents water from entering the cylinder. Pressure gauges shows cylinder and working pressure The correct CO2 concentration in the aquarium water is checked via the display of the CO2/pH permanent test included and can be readjusted if required Contents: 500 g disposable CO2 cylinder, pressure reducer with solenoid valve, 3 m hose, bubble counter with check valve, TAIFUN CO2 reactor + extension set, CO2/pH permanent test with reagents 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. Plant fertiliser systems with CO2 cylinders supply 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 installThe 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 reactor in the aquarium. CO2 thus enters the aquarium and is dissolved in the water with the help of the reactor. The CO2 supply can be interrupted at night when a solenoid valve (night switch-off) is connected. The CO2/pH Permanent Test permanently indicates the amount of CO2 dissolved in the water and can then be readjusted if necessary.SafeThe 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 for about 4 months in its default settingThe recyclable CO2 disposable cylinders can be purchased individually or in a cheaper 3-pack.Conversion from disposable to reusable cylinders and vice versa:All JBL CO2 pressurised gas cylinder systems are compatible with each other. With the reusable system (M system), the union nut of the pressure reducer can simply be unscrewed with an Allen key. The pressure reducer then fits the U system (disposable cylinders).If you have a disposable system, you can make the pressure reducer suitable for refillable cylinders (M system) by screwing on the u-m adapter.
