This is where you get real, human-to-human service. Call up the local “Culligan” or “EcoWater” dealer near you. These folks treat water like sommeliers treat wine—they’ll quiz you about your pH, your well depth, and the hardness of your life. They often sell calcite in bulk by the bag, and they might even deliver it to your driveway.
You’ll pay a bit more for their expertise, but you get a lifeline. When you dump the bag in and your system sputters, you can call them instead of Googling “why is my calcite hissing at 2am?”. Plus, the guys who run these shops usually have a story about a client who accidentally used cat litter instead of calcite. Moral of the story: let the pros help you laugh later.

This is my favorite secret. Places like Tractor Supply Co. or co-ops that sell feed and seed often stock calcite for livestock. Chickens need calcium for eggshells, and your water filter doesn’t know the difference. It’s the same chemical composition (calcium carbonate) but packed in a dusty bag that smells vaguely of hay.

The price? Absurdly cheap. You can get a 50-pound bag for the cost of a fancy coffee. The trade-off is that it’s less processed, so you might rinse out a few tiny pebbles or bits of dust. But if you’re a thrifty soul who enjoys a little grit in their life (literally), this is your move. Just don’t tell your fancy friends you raided a chicken coop for your plumbing.
