I have an almost new Reef Octopus Elite 220SSS skimmer for sale. I only used it 3 months. It works freaking awesome and is still like new. Good for 150-450 gallons. I have the original box and can ship for actual cost. This skimmer was over $1200 new from BRS and was my pride and joy. I just downsized to an 80 gallon all in one. $600 plus shipping
