Just got this from a friend, and it has no markings on it at all. Was wondering if anybody can ID it for me so I kinda know what it's worth. It is a canister filter with built in skimmer, overflow box and attatched ATO. Has a really strong pump that runs it, and other than some dust looks pretty much brand new. Thinking about removing all the trays and bio balls and modding a little light on it to make it a small moveable sump.
