I have a couple old sumps taking up basement space. One is an Eshopps RS-75 and the other is an Eshopps RS-200. Based on pictures I found on the internet I believe these are gen 3 sumps. Both are in good shape and cleaned up really well after last use (just some dust from being stored in the basement). Both where used on tanks with numerous corals so they have never been exposed to copper. I'm asking $60 OBO for the RS-75 and $150 OBO for the RS-200
