SaltvsSalt

[IceTurf]

Hey, somethin to ponder but:

I was just curious what the difference between these two salts are in terms of ability to be used in a salt water tank:
lifeStream sea salt, no additives and completely obtained from the sea, but not rated for salt water tanks
*only thing on ingredients is sea salt*
---
Seachem ReefSalt
Pretty much your basic reef rated salt

The difference is?
