I have my Reef Octopuss DCS-250 INT skimmer for sale and neck extension. Simply put it's too big for my system. I love it and going to buy the same brand just smaller. It is rated for 500g (even higher with neck extension) system. It's only about 1 yr old and runs Great, and taken care of meticulously, Looks like new. Still has about 1 yr left of warranty. Looking to get about $530. Paid $700 with extension Phone: 780-753-7907
