Hydor Slim Skim Protein Skimmer. Looks brand new. Fully cleaned and ready to go. I think I even still have the box and manual.
In tank/in sump skimmer rated up to 65 gallons. I used this on a 40 Gallon and it works amazing. Very adjustable. This is the larger one, not the Nano.
$60
or trade for coral/fish.
