I use it in the well water before doing water change.
Am I wasting my money?
No. While there may not be Chlorine in your water like City water, there are often some heavy metals in well water which can also be harmful and, last I checked at least, Prime helps take care of as well.
Even if you think your water may not be harmful, unless you know the full and exact chemistry of your water, its never a bad idea or a waste of money to use a good conditioner to, at the very least, be on the safe side. I was on well water until just a few months ago and I've always used Prime.
