Lifereef calls it a trickle filter, this sale is just the sump and tower with drip drawer for sale - no bio-balls, canisters or extras. Go to the link and check it out - pic is on the site with write up. I bought it from used from Newguy last summer on a trip to alberta but never i used it. He also drilled one hole (for a float switch i think it) that you might have to seal up depending on your own personal setup. New is $449.00 US which includes the bio-balls and filter pads but no canisters - i am just looking to recoupe my $75.00 for the whole housing.
