Iodised salt
A fresh water swimming pool is a swimming pool that does not use a saltwater chlorinator. A pool that used a salt water chlorinator has salt added to it to so that a salt water chlorinator can electronically convert part of the salt into chlorine. A fresh water pool has chlorine added to it directly either manually or Automatically.
You can buy salt test strips and electronic salt testers at any good pool supply store - Leslie's carries them.

I have never heard of using an anti caking agent with salt. Are you using the right type of salt - - swimming pool salt is the only salt to be used in a swimming pool - NO OTHER. The proper salt to be used will readily dissolve as it is poured into the pool. The salt does need to be brushed as it settles to the bottom of the pool. Have you done that? Did you read the instructions on the proper start-up procedures? k
