2 Red Sea Protein Skimmers, 1 Delux, 1 Standard. Perfect for Frag tanks... I used one on a 75 gallon for a little over a year. I kept the other just incase the first died, but never had any issues.

Boxed up and ready to ship. $125 shipped for the pair. Call dibs and make payment to [email protected] . . . do not send any email questions. This address is only used for paypal.
