Maxspect Protein Skimmer Aeraqua Duo AD600

Due to unforeseen circumstances, I am closing down my aquarium and no longer need this item.
It had a crack when I purchased it from a used goods shop two years ago, but it was still usable without any issues.
Its filtration capacity is incredible, and all my fish were swimming healthily!
