I'm new to marine aquariums I always had fresh water but it's been 25 years since my last cichlid tank and always wanted to try salt water, well things have really changed over the years there are more suppliers more species available that being said are these people certified is there a standard some kind of regulation of livestock and corals to be sure from cultivation to LSF to your door are getting a good product, and who says all these chemicals and equipment are worth the money and do I really need them. I'm not home much so I hired a aquarium maintenance guy and I still lose fish and corals. Someone should put out a list of maintenance companies, where to buy livestock and corals, proven equipment and chemicals and what and who to stay away from
