Whats the difference between the Fluval 305 and 304??

Question

Just bought a filter thinking it was the 305 but its actually the fluval 304 - is there any differences?

Thanks

Answer 1

Other than that the Fluval 304 isn't the newest model (woo woo?), the only difference is price...  The Fluval 305 should be about $20 more for the exact same thing... plus 1.  Really, as long as you paid for a Fluval 304, there's nothing wrong.
