Bog wood in an aquarium releases tannins into the water, turning the water brown. Because bog-wood can remain free of decay for thousands of years it is of use in dendrochronology, often providing records much older than living trees. Wooden artifacts lost or buried in bogs become preserved as bog-wood, and are important in archaeology.
Tannins leaching from an unprepared driftwood decoration in an aquarium can cause pH lowering and coloring of the water to a tea-like tinge. A way to avoid this is to boil the wood in water several times, discarding the water each time. Using peat as an aquarium substrate can have the same effect. Many hours of boiling the driftwood may need to ...
Neon tetras need dim lighting, a DH less than one, about 5.5 pH, and a temperature of 75 °F (24 °C) to breed. There also needs to be a lot of tannins in the water. Neon tetras are old enough to breed at 12 weeks. [23] Breeding neon tetras is considered to be difficult in home aquariums. [24]
Phlorotannins are a type of tannins found in brown algae such as kelps and rockweeds [1] or sargassacean species, [2] and in a lower amount also in some red algae. [3] Contrary to hydrolysable or condensed tannins, these compounds are oligomers of phloroglucinol [4] (polyphloroglucinols). [5]
This species is rarely seen in the aquarium trade, and is usually stocked from specialist breeders or in smaller local fish stores. When found, it usually requires a 10+ gallon aquarium that has a PH of 3.5-6.8, and is decorated with wood, botanicals, a sandy substrate, and tannin stained water. It needs soft and acidic water along with little ...
An aquarium (pl.: aquariums or aquaria) is a vivarium of any size having at least one transparent side in which aquatic plants or animals are kept and displayed. Fishkeepers use aquaria to keep fish , invertebrates , amphibians , aquatic reptiles , such as turtles , and aquatic plants .
A nature style aquascape, suggesting mountains. A contrasting approach is the "nature aquarium" or Japanese style, introduced in the 1990s by Takashi Amano. [1] Amano's three-volume series, Nature Aquarium World, sparked a wave of interest in aquarium gardening, and he has been cited as having "set a new standard in aquarium management". [9]
A "literature survey" related to tannins was pasted on to the end of the article. Since it is not appropriate article content, but may be useful for editors wishing to improve the article, I have moved it here. -- Ed 15:38, 24 July 2014 (UTC) Animal nutrition and effects of tannins
