Which salt for water softener?

Different water softeners use different grades of salt, so check with a water softener supplier.

- Most non-electric, twin-cylinder water softeners for homes use block salt.

- Most electric, single-cylinder water softeners for homes use tablet salt (also know as pebbles or pillows), although some use granular salt.

- Most commercial water softeners use granular salt, although some very large ones have special brine tanks to take PDV (fine) salt.
