Neutral density filters are great for photographing waterfalls, streams, and all flowing water. You can slow down the shutter and give the water a smoothed out look. I use a 3-stop and a 4-stop ND filter for that. Which one did you get? You might want to keep it and have it in addition to a CPL.
Absolutely, keep it. You will find use for it some day and will be glad you did.
