Tetra Value VX Power Filter VX-75 with bonus item

The filtration unit was used in a saltwater aquarium for about 3 months, then lightly cleaned and left in that condition for about 3 years. It was in good working order at the time.
When checked, the power turned on, but it was not filled with water and actually used. The inside of the hose is also dirty.

As a bonus, the following items are included:
- Approximately 2kg of coral sand
- Cleaning pump (dirty)
- Timer (operation confirmed)
- Automatic feeder (operation confirmed, but it moves poorly, possibly due to its age, so please consider this a true bonus item.)
- Light (operation confirmed)

The hose shown in image 8 and the item in image 9 are unused.

Thank you.
