Product information

Disposable or reusable CO2 cylinder?
There are 2 different cylinder types: disposable cylinders that are disposed of and recycled after emptying and reusable cylinders that can be refilled again and again. Many pet shops and gas companies can carry out the refilling. If you live in a region where refilling is a problem, the disposable cylinder can be an alternative. Should the refilling situation improve, you can always convert the disposable pressure reducer into a reusable pressure reducer in 2 minutes by unscrewing the adapter (JBL PROFLORA ADAPT U-M).

JBL refillable CO2 cylinders and many other refillable CO2 cylinders have the following thread connection: W 21.8x1/14 JBL disposable CO2 cylinders and some others (not all!) have the following thread connection: M 10x1

Disposable cartridges are a special case because they have a different thread type: 5/8" UNF. The thread adapter JBL PROFLORA ADAPT U-u201 is intended for pressure reducers like the JBL PROFLORA u201, which are designed to fit these disposable cartridges. This means that instead of the smaller CO2 cartridges with the small pressure reducer, the larger 500 or 1200 g CO2 disposable cylinders can also be used (e.g. JBL PROFLORA CO2 CYLINDER 500 U or 1200 U).

May the JBL PROFLORA CO2 products only be used for the aquarium?

Yes, the JBL PROFLORA CO2 products are designed exclusively for use in the aquarium. The gas contained promotes plant growth and works with fine precision so that even the smallest quantities can be supplied to the aquarium. Constant operation and the safety of the fish are thus guaranteed.

Can two adapters be combined?

No, this is not possible. You can only ever make one change with the JBL PROFLORA adapters. u95 --> u500, one-way Dennerle --> u001 or u001 --> m001.

Example: If you use the small 95 g CO2 cartridges with the JBL PROFLORA u201 pressure reducer to supply CO2 to your aquarium, you can make a connection from the u201 to the u500 disposable cylinders with the existing pressure reducer using the adapter from the JBL PROFLORA range. This means that the JBL PROFLORA u201 pressure reducer can be used with the JBL PROFLORA u500 disposable CO2 cylinders. The pressure reducer remains unchanged. This means that no further "adaptation" with the JBL PROFLORA CO2 ADAPT U - M is possible. This also applies to all other combinations of adapters.
