help on making a brackish tank

[corydoralover]

I need help on making a brackish tank for my black mollys

I've been using aquarium salt but some online forums say to use marine salt. Which one is right?

Marine salt is correct. You don't want to use aquarium salt or any other salt because you want the minerals from the marine salt

Thanks for the info. I'll start using marine salt
