Wet/Dry sump

hey i bought this Aquaclear wet/ dry sump on craigslist thinking it was something that it wasnt.. i paid 80 but i know that if i knew what it actually was i wouldnt have paid 80 so im going to take a loss and try and get 50 or maybe trade let me know what you have.. it dosent have a return pump or any of the hoses just a sump and bio balls.. definatly not what i thought it was.. thanks
