Salt Planner Regenerations, Salt and Top-Ups

The same softener can use twice the salt at its top setting. See the trade-off, then save a top-up reminder.

Salt Planner

Pick your softener and salt setting. See how often it regenerates, the salt and water it uses a year, and when to top up.

Hardness Check

Daily grains = people × gallons × hardness, plus 4 gpg per ppm of iron from your saved Hardness Check. One day of capacity is held back as reserve, as in the makers' manuals. Pounds of salt used per day = dose ÷ days between regenerations. Everything stays on this device.

Want every system side by side? The sizing and salt calculator runs every published dose at once. Why low doses are efficient: grain capacity and salt dose.
