I'm working with well water also. I haven't been there a year yet so I haven't figured it all out. But, I ended up putting my cold water tap throughout the house on straight well water, and the hot water tap throughout the house (and the cold to the washing machine) on softened water. This way, aquariums and house plants can be anywhere without having to worry about extra sodium from the softening process. But, the devices that could get clogged by hard water (hot water heater & washing machine for me) are protected. So far, so good on that front.
The issue that is popping up for me is iron in the water. It's less than 1 ppm. But, it's enough to taste slightly, and enough to create a hair algae farm in all my tanks. I've been trying to adjust my fertilizer to dose more macros to use the micros already in the water. But I don't have the balance down yet.
