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.

I'd check the alkalinity in the dissolved salt to make sure it is OK, since low alk would be the sign of a larger problem.
