Feeler HOB via aqua

I have a used one of these:Via Aqua Multi-Skimmer; Protein skimmer, filter and UV Sterilizer.
It has been used, but works and creates nice dark skimmate it doesn't have the uv sterilizer shown. I am getting rid of it because I upgraded to a octo ext 200 since this was way underpowered for my tank. Let me know if you are interested in it I also might be willing to trade this for a fish (probably a tang) I would add money if necessary. I might make a deal with my friend (also in denver if no one is interested.) here's what im lookin at tang vs angel with extra questions
