Question about hardened salt

[loody]

Hey so i’m using the tropic marin pro reef salt and as i’m nearing the end of the bucket i noticed the salt on the bottom is hardened up a bit against the edges from moisture perhaps, would it be safe to use or should I throw it out since i’ve seen a lot of conflicting information of people saying it’s totally fine and others saying the alk+ cal will get messed up

Safe to use, it’ll just take longer to dissolve

I would use it as well. Id try and break it up first to help it dissolve better.
