Don't waste a lot of money on salt for your hot tub. WE DON'T SELL SALT BECAUSE YOU CAN GET IT CHEAPER LOCALLY. You can use Solar Salt which is about $6 for 40 lbs, Pool Salt $10-12 per 40 lbs, Canning and Pickling Salt about $2 per pound...any sodium chloride salt without iodine or scale inhibiting additives.

HIMALAYAN SALT has minerals that will be oxidized by the chlorine and end up in your filter.

DEAD SEA SALT has a lot of ingredients including minerals. The ingredients will require more Dead Sea Salt to be added than regular salt and the minerals will be oxidized and end up in the filter.

DO NOT USE EPSOM SALT!
