Aquarium cooler, aquarium cooler, operational, Zensui cooler, Zensui

Used for only one month during the summer until last year.
When storing, I thoroughly cleaned the inside with a high-pressure washer and dried it, so it was stored properly each year. The temperature can be set, so it is fine.
The ends of the hose inlet and outlet are cracked, but I used silicone hoses and secured them with bands, so there were no leaks.
The model is old, but it has been properly maintained and used for about one month during the summer.
