Purchased Summer 2024: Zensui ZC100 α Aquarium Cooler
Product Details
This is a Zensui ZC-100 α aquarium cooler. I no longer need it as I'm consolidating my aquariums, so I'm offering it to someone who can use it. What's included is the main unit (including the connection parts shown in the photos) and the instruction manual.
I purchased it new from Charm in the summer of 2024 and used it for two summers only, from summer 2024 to summer 2025. It was used with a 60cm freshwater aquarium containing one goldfish. Since it was for a goldfish, there was no need to excessively lower the temperature, so I believe this cooler is in very good condition and hasn't been overused.
However, please understand that this is a used item before purchasing. Returns will not be accepted for reasons other than those clearly attributable to me.
The original box is not included, so I will pack it carefully in a cardboard box for shipping. As shipping costs are likely to be quite high, please allow me to use Eco-Mercari便 for shipping. If you are in the Tokyo Yamanote Line area and would prefer to pick it up directly, that is also acceptable.
I believe an aquarium cooler is essential in Japan's intense summer heat. It's a good quality item, so I hope you can make use of it. Thank you.
