It's to late now but when fish are sick and people say to add salt and warm the water(freshwater) what kinda salt do you use table salt (the kind you put on ur steak) or aquarium salt (the kind for salt water) thanks
Get some aquarium salt, not marine salt. For most illness the dosage is 0ne tablespoon per 5 gallons of water. This can vary though, so would be better to list specific fish and aliments.
