Basically Brand new Reef Octopus 1000 I got 2 weeks ago. I only used it for a week because I got it as a last ditch attempt to fix my algae problem but I just decided to shut down the tank. Its is in like new condition nothing wrong everything works great. This skimmer is a $200 skimmer that never goes on sale. I am asking $155 Shipped Firm price, already taking a big hit with the tank shut down, so not trying to give the skimmer away.
