Sorry, I'm sure this has already been asked a trillion times, but... I couldn't find it on search :P What's the best filter for a 5-gal, what do you guys use, et cetra... Thanks in advance :D Also, I prolly won't be posting too much this week starting wednesday because I'm going out of town.
I also recommend the Aquaclear 20, I use it on my 10 gallon now. It has an adjustable flow rate so you can make it gentle but for a 5 gallon you probably want an extra baffle like Thunderloon says. My water is always crystal clear thanks to this filter. It is a little pricey but worth it!
