The two main types are solar salt and pellet salt. Pellet salt is 99 percent pure and in some cases is cleaner than solar salt.
For a cabinet-style (all-in-one) unit we recommend pellet salt because the solar salt can sometimes form a bridge at the top of the salt tank, which can block water from reaching the salt.
For all two-piece softening units we recommend solar salt.
Salt usage varies from home to home and is dependent on water usage. On average, a residential softener will use about 50-80 lbs. (or one bag) of salt a month.
For most softening units it is normal to have a little bit of water in the bottom of the salt tank. When the water level rises above the salt it is time for your next salt delivery. Excessive water in the tank (one half full or more) is not normal, and may indicate a problem with the water softener.
Some units, such as those produced by GE and Sears, are dry salt storage units and should not have water in the tank. If you have a GE or Sears unit and there is water in your salt tank your softener may need a repair.
If you need to clean your salt tank, we recommend water with a little bit of bleach.
A little bit of gray foam is nothing to worry about. It is normal for salt to have a little bit of dust on it which can settle at the top of your salt tank. This is nothing to worry about though because the water in your home only passes through the softener and does not enter the tank where the salt is stored.
Yes, this is okay. If you accidentally purchase the wrong type of salt, or if you want to switch to another type of salt it is okay to mix the two kinds together.
