I'm just curious about sea salt. I'd like to know more in depth of why it's not good to use sea salt that has moisture in it to use it in a fish tank. I'm a little confused because it gets wet/ dissolved into our aquariums and I'm pretty sure alot of salt on the market comes right out of a wet environment like the sea. Infact almost all salt comes from the sea/ a body of water. Just would like to know what reactions happen that make the salt unsuitable for an aquarium once damp or exposed to moisture. What could I do to fix it or substitute what was reacted, if there's a way. Again just curious of the science behind it.
