actually, According to the U.S. Navy, there are
actually 361.2 quintillion gallons of ocean water. also one must take into account the depths of the ocean. they sink decaying matter to the depths away from the more delicate life forms.

also the oceans have great oxygenating systems. first and formost-waves and currents, surface area, and even rainfall.

one thing the ocean doesnt have, that is a good export system. everything is either recycled or sunk into the deep ocean. some will say mangroves and other tidal grasses export. but in truth this is a recycling not export.

there are so many factors that we cannot duplicate in a tank that the oceans do. if you want to dedicate a 100g tank to a damsel or two for their lifespan (5-8yrs)(also know that you will need the hardiest of fish to accomplish this) go for it. but it will not be duplicating the ocean or the way it works. you will be creating a balancing act and a precarious one at that. fish and corals grow and will demand more, or die, and in such a balanced tank, one death would be a ecosystem disaster.

im not trying to discourage you, but as the others letting you know what you are up against and the challenges facing you. there is a reason this type of tank is not done by more people.
