Alright I apologize if this seems redundant but I've read both opinions weather marine salt is to be used or aquarium salt. I have a figure 8 puffer tank and I heard that they're mildly brackish in which I should just use aquarium salt. But some refudable people on here said to use marine salt. I was wondering if someone could explain to me the best choice and the reasons why. And which ever it is how much should I use for a 29 gallon.
