Hello all! If you need a nano skimmer I have couple available for anyone getting into the hobby with a small tank; as before, preference given to those who need it but if no interest shown then you can hoard. These little things also make good quarantine tank/system skimmer!! CPR SR3 used in a Biocube 29 (in-sump) AquaC Remora HOB with MJ1200 and pre-skimmer box AFA $ ? $0.00 for BAR members; if you are a guest as I am, become a member!
