JBL ProFlora Cylinder 500M - 500gr universal rechargeable cylinder

Disposable or rechargeable CO2 cylinder?

There are 2 types of cylinders: disposable cylinders that are disposed of or recycled once exhausted and rechargeable cylinders that can be repeatedly recharged. Many zootechnical shops and gas suppliers can charge. If I had to live in a region where charging is problematic, the disposable tank would be an alternative. If the situation for refills improves, you can change at any time in 2 minutes your disposable pressure reducer in a rechargeable pressure reducer by screwing the adapter (JBL PROFLORA CO2 ADAPT U-M). Sometimes aquariaphiles, who, for example, live on an island, cannot carry rechargeable tanks full with the ferry or the plane. In those cases, disposable tanks are sometimes allowed!

The size of the cylinder often depends on the cabinet in which it is intended to hold the reserve cylinder of CO2. A 500 g single-use cylinder is only 31 cm high (more pressure reducer = 38 cm), a 500 g rechargeable cylinder with pedestal measuring 43 cm and a 2000 g 45.5 cm cylinder. Basically a larger cylinder is advantageous, as it must be replaced or recharged more rarely.

TÜV approval of CO2 cylinders.

All rechargeable CO2 cylinders must be regularly approved by TÜV, i.e. every 10 years (at least in Germany). On the cylinder you always find, even if sometimes unreadable, the date of the last approval TÜV and sometimes even the year of the next approval.

CO2 tank for all CO2 plants. It provides aquarium plants with carbon dioxide, their main nutrient, thus preventing the growth of algae.

Since CO2 is liquefied under pressure, CO2 cylinders must stand vertically during the exercise.
