less stresses on fish
In general, adding a teaspoon of instant ocean salt mix to the gallon reduces stress in fish, thus making them healthier and longer lived. Before I got into adding salt to freshwater aquaria, I read an article on the internet and the article says adding a teaspoon of salt per gallon is sort of like a magical elixar for sluggish fish and fish in general. I agree with that ALL THE WAY. THEIR AIN'T NO TWO WAYS ABOUT IT! I've been adding salt to make my beloved fish healthier and I always will.
