Forgot I still had this. I listed it for sale a long time ago, but not any real interest. Came across one of the boxes it is in today and thought I would offer it up for free.
More info can be found here.

It is a great skimmer, I just don't see myself ever setting up a tank large enough to need it again. This thing takes a really big pump to drive it. I have the "classic" model of the 830, also have the waste collector and the injector housing. It has sat for a long while so it might need new o-rings.
I live in Point of Rocks MD and not much spare time these days, so if you want it you have to come to me.
PS, I HAVE GOTTEN SUCKY MESSAGES FROM PEOPLE IN THE PAST WHEN I GAVE SOMETHING AWAY AND THEY THOUGHT THEY SHOULD HAVE GOTTEN IT FOR WHATEVER REASON, SO IF BY CHANCE I GET LOTS OF PEOPLE THAT WANT THIS, I MIGHT MAKE PEOPLE GUESS NUMBERS FOR IT OR SOMETHING.
