Hi, heard a lot of people around said that Garlic extreme is a good source to improve fish immune system, can we add them directly to tank? How much to add? And if I were to soak food with it, how do I soak? Get a container and soak? No need to add water? What about live food? Sorry for all the question, but I would really like to know more about it, I'm going to start using it soon, thanks all in advance.
