I just used a bag of water softener salt, and as I was pouring it into the brine tank I noticed there were a few pieces of salt with yellow on them. Does anyone know what might be causing the yellow color? Is it a cause for concern? See the picture below. It seems like most pieces with yellow have embedded particles in them, perhaps they are bits of rust that might be causing the discoloration?
Anyway, this is a quality brand of salt, supposed to be 99.6+% pure. I've been using it for a few years and have never seen this before.
