The Berlin Method of biological filtration is method for keeping an aquarium, typically a saltwater aquarium, clean. Filtration is a mechanical or physical operation which is used for the separation of solids from fluids (liquids or gases by interposing a medium to fluid flow through which the fluid An aquarium (plural aquariums or aquaria) is a Vivarium consisting of at least one transparent side in which Water -dwelling Plants A marine aquarium is an Aquarium that keeps marine plants and animals in a contained environment It is basically the use of ample live rock (rock with live marine organisms and bacteria on or in it) in a refugium or tank. " Live rock " is rock from the ocean that has been introduced into a Saltwater aquarium, which confers to the closed marine system multiple benefits desired by the salt Most often a separate tank containing a large amount of live rock but without fish or corals is linked to the main aquarium via pumps and tubes. Corals are Marine organisms from the class Anthozoa and exist as small Sea anemone –like Polyps typically in colonies of many No substrate is used in a Berlin setup to facilitate the vacuuming of debris, although a deep sand bed, biological filter setup may be used in conjunction with the Berlin. The substrate of an Aquarium refers to the material used on the tank bottom A deep sand bed (sometimes abbreviated DSB) is a Filtration method used in some Saltwater aquariums A deep sand bed similar to the Berlin Method A protein skimmer is used to remove organic solids. A protein skimmer is a device that extracts Protein and other Organic matter from water The theory is that anaerobic bacteria deep within the rock convert nitrate to free nitrogen gas. An anaerobic organism is any Organism that does not require Oxygen for growth and may even die in its presence The Bacteria ( singular: bacterium) are a large group of unicellular Microorganisms Typically a few Micrometres in length bacteria have
The typical rule of thumb is to use from 1. A rule of thumb is a principle with broad application that is not intended to be strictly accurate or reliable for every situation 2-4. 0 kg (. 75 to 2 lb) of live rock per 4 litres (~ 1 gal) of aquarium water depending on the density of the rock – or filling the tank up 2/3 of the way to the top. The pound or pound-mass (abbreviation lb, lbm, or sometimes in the United States #) is a unit of Mass " Live rock " is rock from the ocean that has been introduced into a Saltwater aquarium, which confers to the closed marine system multiple benefits desired by the salt The benefit of using live rock is fourfold: First, live rock acts as a biological filter, adding beneficial bacteria. " Live rock " is rock from the ocean that has been introduced into a Saltwater aquarium, which confers to the closed marine system multiple benefits desired by the salt Secondly, it introduces an abundance of marine life into the aquarium that many fish, invertebrates and corals use for food. Fish are aquatic Vertebrate animals that are typically ectothermic (previously Cold-blooded) covered with scales, and equipped with two An invertebrate is an Animal lacking a Vertebral column. The group includes 98% of all animal Species — all animals except those in the Chordate Corals are Marine organisms from the class Anthozoa and exist as small Sea anemone –like Polyps typically in colonies of many Thirdly, it provides a natural reef appearance with ample places to locate corals. Lastly, live rock will also help balance and stabilize PH in the aquarium. pH is the measure of the acidity or alkalinity of a Solution.
