Vertex Calcium Reactor RX-C 6D Excellent Condition

This item was purchased about 3 years ago from a certain aqua shop in Aichi Prefecture as a used item in excellent condition with only a few months of use. Unfortunately, I had planned to set up a new coral tank, but had to abandon the plan due to personal circumstances. I have kept it carefully stored without using it. I had intended to use it someday, but since that plan is no longer in place, I would like to pass it on to someone who will use it with care.
What is shown in the photos is everything included. The original box is not included.
The company that produced this product no longer exists, making it difficult to purchase. I believe this is an extremely rare product that is rarely seen on auction sites or flea market apps.
Please consider this opportunity.
