I have for sale about 5 months old Magnum HOT 250gal/hour hang-on canister filter just like this
http://www.marineland.com/products/consumer/con_hotmag.asp
I used this filter only about 2 or 3 times for 3-4 days at a time to polish my water.
Filter comes with brand new, never used, Micron Filter and some extra fittings.
Brand new goes around $100-$110 plus tax. First $65 takes it.
Lcoals only please.
