The JBL PROFLORA CO2 ADVANCED SET is a complete fertilisation system for freshwater aquariums from 40 to 600 litres. Designed to enhance plant health and reduce algae, it delivers consistent carbon dioxide directly into the aquarium water. This set includes a solenoid valve for night-time CO2 shut-off, a TAIFUN CO2 reactor for effective gas dissolution, and a CO2/pH permanent test with reagents for ongoing monitoring. Ideal for aquarists with an existing CO2 cylinder, the set is easy to install and ensures safe, reliable CO2 distribution.

Compatible with both refillable (W21.8x1/14) and disposable (M10x1) cylinders, the system allows for flexible setup. For those requiring a cylinder, the JBL PROFLORA CO2 CYLINDER 500 U is available separately or as part of a bundle. Each pre-filled 500g disposable cylinder is TÜV certified, includes a rubber base for stable placement, and connects via standard M10x1 external threading—making it fully compatible with the included pressure reducer and solenoid valve.
