Actually, I was going to go with the 330 (and would have preferred it), but it wouldn't fit my aquarium hood. Really the only reason I mentioned that I get by with a 170 was to help point out that a 330 AND a UGF is overkill.Originally posted by vato
The Penguin 330 is an awesome filter, so I might stay with that, but if cgrabe says a 170 will work that may be the better option.
Having a tall aquarium can be such a pain
