Zensui External Protein Skimmer Eternal Nano Skimmer QQ3

I am selling this because I am downsizing my aquarium and no longer need it. It was used from January 2025 for approximately 1 year. I have checked its operation and there are no issues. As it is a used item, there are some minor stains, but I would appreciate your understanding.
