Euro-Reef RS-80 Skimmer is in great condition. We loved this skimmer. It’s a great size, easy to set up and easy to maintain. It has a fitting to drain skimmate to a separate container (we used a 2 liter bottle). It’s rated for a much larger tank, but we successfully used it on our 120g cube tank reef FULL of SPS corals. Would work great for smaller tanks also. Pump shown is not included.
