Live Rock

picture info	Live Rock Live rock is rock from the ocean that has been introduced into a saltwater aquarium. Along with live sand, it confers to the closed marine system multiple benefits desired by the saltwater aquarium hobbyist. The name sometimes leads to misunderstandings, as the "live rock" itself is not actually alive, but rather is simply made from the aragonite skeletons of long dead corals, or other calcareous organisms, which in the ocean form the majority of coral reefs. When taken from the ocean it is usually encrusted with coralline algae and inhabited by a multitude of marine organisms. The many forms of micro and macroscopic marine life that live on and inside of the rock, which acts as an ideal habitat, give it the name "live rock". Origin Live rock is harvested for use in the aquarium from reefs, either from natural or human breakage. It may also be "seeded" from small coralline rocks by an aquaculturalist in warm ocean water, to be harvested later. Live rock can also be seeded by add ...

picture info	Reef Aquarium A reef aquarium or reef tank is a marine aquarium that prominently displays live corals and other marine invertebrates as well as fish that play a role in maintaining the tropical coral reef environment. A reef aquarium requires appropriately intense lighting, turbulent water movement, and more stable water chemistry than fish-only marine aquaria, and careful consideration is given to which reef animals are appropriate and compatible with each other. Components Reef aquariums consist of a number of components, in addition to the livestock, including: Display tank: The primary tank in which the livestock are kept and shown. Stand: A stand allows for placement of the display tank at eye level and provides space for storage of the accessory components. Sump: An accessory tank in which mechanical equipment is kept. A remote sump allows for a clutter-free display tank. Refugium: An accessory tank dedicated to the cultivation of beneficial macroalgae and microflora/fauna. The re ...

picture info	Biological Filter A trickling filter is a type of wastewater treatment system. It consists of a fixed bed of rocks, coke, gravel, slag, polyurethane foam, sphagnum peat moss, ceramic, or plastic media over which sewage or other wastewater flows downward and causes a layer of microbial slime (biofilm) to grow, covering the bed of media. Aerobic conditions are maintained by splashing, diffusion, and either by forced-air flowing through the bed or natural convection of air if the filter medium is porous. The treatment of sewage or other wastewater with trickling filters is among the oldest and most well characterized treatment technologies. The fundamental components of a complete trickling filter system are: * a bed of filter medium upon which a layer of microbial slime is promoted and developed; * an enclosure or a container which houses the bed of filter medium; * a system for distributing the flow of wastewater over the filter medium; and * a system for removing and disposing of any sludge fr ...

picture info	Concrete Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients.

picture info	Aquascaping Aquascaping is the craft of arranging aquatic plants, as well as rocks, stones, cavework, or driftwood, in an aesthetically pleasing manner within an aquarium—in effect, gardening under water. Aquascape designs include a number of distinct styles, including the garden-like Dutch style and the Japanese-inspired nature style. Typically, an aquascape houses fish as well as plants, although it is possible to create an aquascape with plants only, or with rockwork or other hardscape and no plants. Aquascaping appears to have begun to be a popular hobby in the 1930s in the Netherlands, following the introduction of the Dutch style aquascaping techniques. With the increasing availability of mass-produced freshwater fishkeeping products and popularity of fishkeeping following the First World War, hobbyists began exploring the new possibilities of creating an aquarium that did not have fish as the main attraction. Although the primary aim of aquascaping is to create an artful underwater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
