Kamihata Kaido Daruma Protein Skimmer - Operation Confirmed - Includes Spare Pump

This is a Kamihata Kaido Daruma.

I received it from an acquaintance and used it in the filter tank for about 3 years, where it performed its role without any issues.

It has been washed with fresh water, but there are signs of use.
The air tube has been replaced with a new one that was in storage, so it is ready to use immediately.
The instruction manual is a printout from the internet.
The original box is not included.

Everything shown in the photos is included.

I am selling this as I am retiring from keeping aquariums.

Please understand that this is a used item before purchasing.
