Not sure which I'll need to do, harden or soften the water. I know I can use peat moss to soften and limestone to harden water. But how long does each method take? How do I know how much to use? I live in Kentucky, which is pretty much made of limestone, but how will I know the rocks are safe? I've heard I can just buy peat moss from a garden center, but is that really safe? Thanks so much for any help!
