salt mix

[kwandrsn]

I got 3 boxes of 10 gallon reef crystals. They are a little old and the salt looks moist. It isn't hard just moist.

Any opinions?
One has 2 black spots ,possibly mold?

They are not soaked and not hard just a little moist

Personally, if it's only 30 gallons worth of salt, and there's any question, I'd toss it. Is saving a few dollars (literally) of salt worth the slightest possibility of it being bad??

True, just 30 gallons of salt lasts me 7 weeks worth of water changes. I just didn't know if anyone has used moist salt before
