You can use either tablet or block salt in your water softener. With tablet salt, top it up no higher than 2-3 inches from the top of the cabinet lid. Thereafter top up your salt either once a week or you can wait until the salt level has fallen to about 4-5 inches from the bottom. If you use block salt, only add 1 or 2 blocks at a time depending on space availability and the cabinet water level. Your salt usage will depend on your household water usage, how hard your water is and your water softeners resin bed capacity.
