Weetabix7, I got a bad batch that had high alkalinity.
Was it through out the whole bucket? One of the things I do when I get buckets and or bag is mix up the salt before I use it just in case there is some settling of sorts. That goes for any brand I have ever used.....I have always wondered if the salt is broke down like this- each particle of salt has everything in it or if it is just a mixture of minerals that get blended and then poured into a bucket or bag. If each particle of salt had 100% of the minerals and elements it wouldn't matter. But if it is just a mixture of minerals and elements then I can see where the parameters could change from each batch of new water mixed from it. That is one of the reasons I mix up the salt before I use it cause I don't know and I'm not going to take a chance.....
