For sale tunze DOC skimmer only used about 5 months bought new from aquatic warehouse. Rated for up to 66 gallons pretty good skimmer but I'm upgrading tanks soon so I got a bigger skimmer asking $90 will consider trades. retails $154 pm me if interested. I still have it in my sump has corilin Algee on the outside along with all the regular sump creatures I will clean it off if requested.
