• Piston-controlled precision pressure reducer with pre-set working pressure and 2 pressure gauges for bottle and operating pressure. Filled, refillable 500 g storage bottle. Additional pump for diffusor not required. With CO2 permanent test and non-return valve.
• 100 % loss-free solution of CO2 in water through high-diffusion vario diffusor.
• Contents as for Profi 1 with additional solenoid valve (pre-fitted) to switch off CO2 supply at night (JBL Proflora Solenoid Valve vario). 

JBL CO2 SET Profi 1 provides aquatic plants with the vital nutrient, CO2, easily and conveniently creating the ideal conditions for a luxuriant underwater garden. At the same time, by regulating the supply of CO2 the pH level can be adjusted to around 7, the range best suited to the majority of fish and plants. An easily operated precision pressure regulator with pre-set operating pressure enables precise dosages to be made. The CO2 vario diffusion system can be adapted to fit any aquarium height using extension sets (available in specialist aquarium stores). A stock of 500 g of CO2 should last a long time, without changing the gas bottle.

The amount of CO2 required depends on the volume of water, the carbonate hardness, the pH value required and the consumption by the plants. Begin with one bubble in every other bend in the device and slowly increase the number over a period of several days as required. The pH value serves as a control value. Depending on the carbonate hardness, we recommend a pH value between 6.8 and 7.4. Further details are given in the product information sheet of the enclosed CO2 Permanent Test.
