Zensui Protein Skimmer Genesis DC500 (Price Non-Negotiable)

I am selling this because I no longer need it due to a change in my aquarium size.
I purchased it new from Charm and used it for 2.5 years without any particular issues.
I believe this is a great deal, even if you consider replacing the motor or other parts.

Zensui Protein Skimmer Genesis DC500

Features
This is an internal-type protein skimmer designed for use within a filtration tank.
Equipped with a DC pump, it solves the common problem of noisy operation associated with protein skimmers and also achieves energy savings.
It features an efficient half-cone body.
Minor improvements have been made to each part to facilitate maintenance of the pump and other components that affect filtration capacity, with an easy-to-install and remove design.
The skimmer's water level can be easily adjusted by rotating the easy pipe left or right.
By removing the cap and attaching the included drain tube, you can collect wastewater in a separate container.
The uniquely shaped bubble plate regulates bubble movement, providing stable filtration capacity.
