Back to Nature Natural Reef Aquarium Methodology by Mike Paletta (Aquarium USA 2000 Annual)
Back To Nature Natural Reef Aquarium Methodology by Mike Paletta (Aquarium USA 2000 annual) The reef hobby, that part of the aquarium hobby that has arguably experienced the most change, is ironically also an example of the axiom that the more things change the more they remain the same. During the past 10 years we have seen almost constant change in reefkeeping practices, and, in many instances, complete reversal of opinions as to which techniques or practices are the best. We have gone from not feeding our corals directly to feeding them, from using some type of substrate to none at all and then back again, and, finally, we have run the full gamut from using a lot of technology to little or none. It is this last change, commonly referred to as the "back to nature" or natural approach, that many hobbyists are now choosing to follow. Advocates of natural methodologies have been around since the 1960s, when the first "reefkeeper," Lee Chin Eng, initiated many of the concepts and techniques that are fundamental to successful reefkeeping. Mr. Eng lived near the ocean in Indonesia and used many of the materials that were readily available to him from this source. "Living stones," which have come to be known as live rock, were used in his systems as the main source of biological filtration. He also used natural seawater and changed it on a regular basis. His tanks were situated so they would receive several hours of direct sunlight each day, which kept them well illuminated. The only technology he used was a small air pump, which bubbled slowly into the tank. -

Anil, Senior Scientist, Vizhinjam Research Centre of Central Marine Fisheries Research Institute, Vizhinjam, Kerala - 695 521. E-mail : [email protected] Introduction A reef aquarium or reef tank is an aquarium containing live corals and other animals associated with coral reefs. These aquarium setups attempt to recreate marine life like that of the natural coral reef, often spectacularly coloured mixed reef that blend hard and soft corals from different parts of the world. Unlike the marine aquarium, which are built to house various types of fish, the main attraction in many reef tanks are the varieties coral and other invertebrates. Some points to remember before setting up a reef tank are the following: 1. Power access A reef tank requires a lot of power unless you use natural lighting, and even then it can be substantial. A 1000 L reef uses close to 30 amps peak, which means that you will need at least two dedicated breaker circuits of at least 15- 20 amps each. One can also expect fairly hefty power bills for the tank. -
