I have a Hoya ND8 (3 f-stops) filter for this purpose and it's great if you have fast flowing water in fairly dull conditions. Check your histogram carefully to see if the peaks are nicely grouped in the middle and not pushed hard over to the right, otherwise you might also need to dial in a little negative exposure compensation so you don't clip any of the highlights.
If you're shooting in very bright conditions you will need to use either a polariser with the ND8 or have one of these fantastic 10 f stop ND filters, because using a slow shutter speed there will be way too much light entering the lens and you'll end up with grossly over-exposed shot.
