Once thought to be far too difficult for mere mortals, a successful marine aquarium is now well within the grasp of any interested hobbyist. One of the biggest reasons for the increased emphasis on saltwater fishes and invertebrates in the aquarium hobby is that technological advances in aquarium equipment, coupled with advances in knowledge about marine biology, have made the keeping of marine animals of all types easier than it has ever been before. The tanks are better, synthetic sea salts are better, filtration equipment is better, and lighting systems are better. These improvements make it much simpler for aquarium hobbyists to reap the rewards that the marine end of the aquarium hobby can bring, including setting up a miniature coral reef and enjoying its fascinating, colourful diversity of life forms, all with 'no grief to the reef'.
