Hi guys, im new to aquariums and it sounds like you guys know what your talking about on this site. I just got a 55 gallon for my birthday and im looking for other options for my filter. Right now I have an Aqueon power filter, 325 gallons per hour:
(sorry, I cant post links yet but google image search "aqueon power filter 55" to see a picture if you dont know what one im talking about)

My problem with it is that I live in an appartment and the tank is pressed up againts my neighbors wall, the pump itself is not loud but the waterfall effect it gives off is. I was wondering if there are any other options I could go with that maby dont have that waterfall?

I honestly know nothing about aquariums and dont even know if the filter I have now is a good one? I would really appriciate any opinions or advice you guys have to offer.
