I got these recently from a LFS going out of business last summer. I did not put them in my tank until early Fall last year. These are work horses that will last a LONG time. They retail for almost $200 each. I am selling for $150 shipped (CONUS) (selling local for $125 if picked up and Cash). I have cleaned these so you can see they look almost new. I just bought a set of Neptune Wav pumps from a local reefer and I don't need these. $150 shipped CONUS for BOTH pumps.
