There was nothing directly wrong with the salt, when I used it again after letting it mix for less than a week everything was fine. But for some reason it seems seachem can not be allowed to sit and mix before use for a month.

Interesting.

I make about 25G at a time with Deltec salt and then I do 5G a week changes. So some of my new water is just sitting there circulating for over a month sometimes. Never had a problem but this worries me a little.
