Good condition skimmer -- great for small to medium tank.
Designed to operate in tank. There is a big ole magnet to hold it in place at the correct depth. Seemed to work best in this configuration.


That said, I also ran it in sump using the (included) in sump conversion kit. Skimmer was a bit more finicky with this conversion, but still works.
Very quiet -- and Tunze quality at a killer price. Just the sump conversion was almost $50!
Before it was discontinued... here is a link from marine depot:

No cashiers checks -- paypal or cash only. Will consider shipping on your dime.
