Open bag of Seachem salt

Is there an issue with leaving a bag of salt open for a few months.....dumb question but I would like to be sure before I do a water change with it. Thanks

The potential problem will be precipitation of calcium carbonate.

Mix it up and measure the alkalinity after it is clear. If the alkalinity is OK for you, the salt is good to go and no need to measure calcium.

If it is too low, you can either supplement it (and maybe check calcium too), or not use it.

Should not be an issue.
