Title says it all. IM Skim Mate skimmer, smaller version. Rated by IM for tanks up to 25 gallons.
Works perfectly, very good condition. I just swapped it out for a new Ghost skimmer. The ghost does not work any better, just suited my under the cabinet tank better.
$50.00. Only trades/partial trades I would consider are a long handled tank scrapper and/or a refractometer. No corals, livestock etc.. I do not have room in my tank for anything else.

I am in SE Portland, but willing to ship.
Thanks.
