There are lots of people who use these additives in their reef with great success and there are lots of people who do not use these additives in their reefs with great success :-). Thus you will get opinions from both sides.

Only you can decide what camp you want to join. Team Jacob or team Edward? :-)

If you are just starting out I personally would not even think about these additives yet. Start with the basics, salt and water. That's all the fish really need. When you are ready for corals then evaluate their needs on a species by species basis as they are all very different in their requirments.

Every home has water, so to answer your original question the only thing you really need to stock up on at the moment is salt :-D
