Helpful magazine to help start out your aquarium. I have not subscribed to it yet, but will as soon as I get myself together. I couldn't decided if I was going fresh or salt water. There was an article on the magazine I had picked up that made the decision simple for me. It went on to give a rough estimate on the list of things you would need for each. Then it went on to teach on the proper care for each of the aquariums and what types of things you might want to do to keep it clean.
