I used well water for 6 years without any issues. Just because it is a well does not mean it is hard water. Mine was moderately hard but could of been worse. Regardless of keeping fish or not you should test well water yearly if you use it for drinking. I never added anything to my well water, no dechlor or heavy metal binder. Never had a single problem. Even spawned german blue rams in it and lots of other fish. Also remember while some heavy metals are certainly toxic they are normally present in low levels in drinking water. Quiet a few heavy metals are also essential nutrients, but most of these are provided in fish food, like copper, zinc, iron, maganese, and cobalt. Only things we tested our well for regularly was bacteria, nitrate, and copper. It had 25ppm of nitrate but I never had a problem using it, my plants loved it.
My current tap drinking water is chlorinated town water and contains levels of Uranium, Radium, lead and arsenic. I use it for all my tanks and don't use any heavy metal binder. The radium is pretty close to the maximum allowed level. I also dose CSM+B which is a trace fertilizer containing copper, iron, zinc, manganese, and other elements on top of whatever levels are in my tap water.
