Water Treatment Tools: Hardness, Softener Size, and Salt Use

Client-side water treatment tools for estimating water hardness, softener grain capacity, salt usage, and filtration cost.

Water Hardness Converter

Convert a water hardness reading between grains per gallon and ppm, then read the standard soft to very hard classification band.

Estimate daily grain load and a recommended softener grain capacity from household size and water hardness before a professional water test.

Estimate weekly and monthly softener salt use from grain capacity per regeneration and how often the unit regenerates.

Estimate total cost of ownership and cost per year for a reverse osmosis system from upfront price, annual filter cost, and years owned.

Estimate how many days a water softener runs between regenerations from household size, water hardness, and the softener grain capacity.
