I'm just wondering what you guys use for filters and how they are as far as noise goes. Since my tanks are all in my bedroom I need something silent or darn close to it because I have multiple tanks. The noise issue is really what's keeping me from getting any more fish even though I have the space. I did find one filter that is completely silent (it's a mini canister filter) but I can't get it unless I spend $10 on shipping and the filter is $20 and a little oversized for a 5 gal tank. Any imput would be appreciated. Thanks!
