Hardened Salt

Hi everyone!

So I opened up an older salt bucket tonight to find that the top layer was as hard as rock. I guess it was not sealed up very well. I was able to break through the tough layer, and there is soft salt beneath it. I was wondering, is it acceptable to use the soft salt under the hard?

Question 2: Should the hard stuff be discarded, or can that still be used also? Thanks! I have never really run into this situation before.

Use it all. Not a lot of contaminants in the water that is in our air. Salt is a desiccant that is great at sucking water out of the air.
Crunch it up and make sure you mix it well before you use it.

No, don't use it. Clumped and aired out salt will not mix to the correct salinity. You can still use the salt that's not clumped underneath.

Sure you can use it. Break it up again and remix it. I mix to a refractometer, so clumping means zero to me.

Im curious as to why you think it wouldnt mix to the right salinity. Salt is salt and it being hard isnt going to change that at all.

Now on the other hand, it might mix a little cloudy which could be problematic.

Why would it mix cloudy?

I would imagine potential precipitation of the other elements in the salt mix. The calcium and alkalinity crystalizing would be my first thought.

Hum...I thought it was crystallized already. If you look at calcium and sodium bicarbonate under magnification, they already have a crystalline structure, just very small.

Im thinking more about how they react together when magnesium isnt around to prevent it.

That makes no rational sense at all. It may take longer to go into solution, but that is really all.


Why not just add water to the remainder of the bucket and make a slurry and then just use what you need. That would be the easiest and surest way to get it all mixed again.
If sealed I doubt it would become an issue and you would most likely use it all long before any issue could develop.
