Abundant Flow Water Calcite is simple, cheap, and ridiculously effective. It’s a rock that fixes your water and tells a great story. You can impress dinner guests with your knowledge of limestone chemistry. Or just enjoy better-tasting water in secret.
Either way, you win. Go get yourself some magic gravel. Your pipes will thank you. Your taste buds will throw a party. And you’ll never look at a sidewalk the same way again.
P.S. - If you ever run out, just crush an eggshell. I’m not kidding. (But buy the real stuff first, okay? Don’t be a hero.)
