Does clumping salt indicate the mix went bad?

[Audi0s]

I left my lid a little loose on my bucket of Red Sea Coral Pro, and now I see large clumps of salt near the top, Im thinking bc of the humidity. Most of the mix is still salt, theres just a few larger chunks at the top. Should I continue using or dump it? And where should I dump it if I need to? Thanks

Unless its all like a block of cement id use it. Mix it good first, maybe break clumps up

Yea, usually my water mixes for at least a day. K glad I dont have to throw 40lbs of salt away!
