Brackish Water Salt?

[Ripley]

Just wondering what kind of salt do I have to add to my tank to make it brackish? Is it just plain aquarium salt or marine salt? I have Bumblebee gobies and want to take a stab at breeding them so I want them to be happy and healthy.

Marine salt is what you need, aquarium salt is just sodium chloride .

And bumblebee gobies will routinely breed in freshwater too (It's a myth that they need brackish water)

If you've got a high enough Ph of around 7.5 to 8, they were feeding well, and had their own territories, then salt wouldn't be necessary. Salt won't harm them, but it's not essential.
