So I bought the small Whisper Filter, which I know has a little too strong of current, but I was going out of town for two weeks and didn't trust my little brother to change the water. Now that I'm back I would like to find another filter thats just as effective (this thing has the water crystal clear!) but with a lighter current. Someone recommended a nice looking min-filter, but the thing is I would really like one that you put in the tank stuck to the sides, with a small tube trailing out the back, not that hangs over the back because then the lid to my tank will not fit. Any suggestions? Oh, my tank is only a little over a gal, so i would need one made for 1-3 gal tanks. Please help!
