There's volumes on filters around here.
If there is a lot of calcium etc in the water, that means a lot, of it, is suspended and not just dissolved. A good charcoal filter with silver, or ceramic with charcoal center and so on will get most of the suspended and even gather some of the dissolved. Silver in the charcoal will get a lot, of nasties. The blue 10 inx2.5in filter at CW is a good one. They will take out the chlorine, which is usually excessive and makes the water terrible on it's own accord. It also eats at metal plumbing. The big 10x4 in whole house filter housing will handle a number of different spec filters. We run one of them as primary to get sediments and then another or the blue one from cW, whatever the name is or the ceramic. Slows down flow some but the tank is full of filtered water and if need be turn the pump on. We had wonderful well water at our last home. I held it up a glass of it to light and could see calcium flakes. Filter took it out and toned down a lot. Water good enough to make whiskey. We frequently took water to Mama's Neighbors. Friends would take water home with them.
the good filters will get rust, sulfur, lead and so on. Lot of different ones out there on the net.
We add back some chlorine, sold at CW and elsewhere and it is night and day better than stuff in municipal systems, too keep water, in the tank, in good shape.
