I got a watersoftner installed today. The Installing company sells
"Dura-Cube" by Cargill for around $6.00 for 50lbs. Of course they set me
up
with my first 250 pounds. The salt is sort of in a chip form. The
Installer said rock salt and "solar-salt" are inferior and are less pure,
so
do not use them. Is this so? What brand of salt do you use? And the
cost?
And of course where to purchase?
Is the $6.00 for the "Dura-Cube" too much or about normal. I can purchase
the salt on my own at the dealer when needed, but I am not paying them a
service call to bring it by.

Rock salt has many impurities and should be avoided. The price you have for
the Dura-Cube is not bad and yes, it is a bit better than solar salt. For
the slight cost difference in a year, I'd continue to use it.

That said, we use solar salt at work. I buy 2,000 pounds at a time and pay
about $5 a bag delivered. We treat about 8,000 to 11,000 gallons of water a
day. Twice a year we drain and clean the brine tank.
