I just bought an AquaClear 5-20 US Gallon power filter for my 5 gallon tank, it seems pretty good, but is that a good brand? it was $44.99 plus tax, which I thought was a bit expensive, but was it worth it? There was a Fluval one too, but $75, I'm not paying that much just to put in a fry tank, (no offense!) what do you guys think?
