I set a post in the fresh water getting started forum and people told me fluvals are good, and the people that have them said i can't go wrong with it. Well i went to a lfs and the kid that works there knows what hes talking about you can just tell and he said that fluvals are the worst and he always see's them coming back to the stores broken. Whats the deal, did i screw up when i ordered the fluval 404 for my 55 gallon tank?
