SNM Calcium Reactor Full Set

This is a full set calcium reactor.
It's a complete set that includes 10 CO2 cylinders, calcium media (opened and about 3 spoonfuls used), and a regulator (Oasis CO2 set, which costs around 9,000 yen new), so you can start using it right away.
The reactor body was purchased used and has been used for about 2 years. It was serviced by a shop last year.

Price negotiation is possible, but if someone purchases it at the full price later, that purchase will be prioritized. Please request a price reduction with this risk in mind.

This is a private listing, so please understand that the packaging may not be perfect.
However, I will do my best to pack it securely, including using bubble wrap, so the shipping time is set longer.
I will strive to ship it as soon as possible, but please understand.

The part where the screw is wound to prevent the pump from coming off has some rust, but this can be resolved by replacing it with a new one from a home improvement store.
Also, as this item has been previously owned, please refrain from purchasing if you are sensitive about such things. No claims, no returns, please.

Thank you for your understanding!!
