Why not to use io salt

Salt was very dusty instead of powdery/grainy. Had to hold my breath while taking it from the bucket and adding it to the mixing tank - dust everywhere.
It also needed 7 cups instead of 6 cups to mix 12g of water. Obviously the salt was messed up. But it still never killed anything.

I turned off my Mag pump 6 weeks ago and have just turned it back on this week as it took 2 weeks for it to drop enough to start dosing again.

I test my new salt water before each WC to keep an eye on things and adjust it accordingly

So where on the bucket do you find a batch #, there's a bunch numbers around the sque but it's the same # on all my empty buckets
