Aquarium Advice FINatic
does anyone have both? i want to know which is quietest. i'm looking at either an xp2 or the 404 for my 55gal. i love my emperor 400, but with the a.c. on too... there's an awful lot of white noise in my living room... i've looked into both filters and i think functionality is pretty even between them, so it really comes down to which makes the least amount of noise.
