Hello everyone. Up for sale is a used reef octopus extreme 160 protein skimmer. It is in great working condition and comes with everything needed. This is a great skimmer and has worked out great for me. I am selling it because i have upgraded to a larger reef octopus. I am asking 175.00 or best offer plus shipping. I will ship anywhere in the U.S. Message me with any questions or offers. Thanks again!!!
