Rated 3.0 out of 5.0 by Finely ground salt A lot of salt for water softeners comes in marble-sized chunks. That form seems to dissolve much more slowly than this product. I suspect it makes a much saltier concentrate in the tank, which may clean the softener better at first, but be prepared to have to refill it more frequently. I'm not sure mine needed that level of cleaning. This isn't an "easy open" bag. May 12, 2015
Rated 1.0 out of 5.0 by Morton salt crystals This was the first time in 18 years that I tried a different product for our water conditioning system. I usually use the Morton pellets. Well this is the first time that I have had the salt solidify within the tank. We had to remove some of the salt and then work to break up the solidified mass. I will definitely go back to using the pellets. December 17, 2014

Rated 5.0 out of 5.0 by Grass Killer I used 1 bags of Morton Salt White Crystal 40 lb. Water Softener Salt , sprinkle over 1,000 sf of grass. 1 week later all grass gone. Kill all grass slower than Roundup but it safe and cheap. 1 year later grass still not come back yet! ...Work like a champ. March 3, 2011
