Algae
( Added: Fri Apr 28 2006 Hits: 100)
|
| Almost every aquarium is plagued at some point by an "algae bloom." "Algae blooms" can be fueled by excess light, especially sunlight, and excess nutrients,
especially nitrate and phosphate buildup. Thus "algae blooms" can often be prevented by regular water changes and placing the tank away from direct sunlight.
There are several types of algae common in the aquarium: |

Algae and Fungi
( Added: Fri Jan 13 2006 Hits: 110)
|
| The algae comprise several different groups of
organisms, which are not in the kingdom plantae but in
the kingdom protista, that produce energy through
photosynthesis. The most conspicuous are the seaweeds,
multicellular algae that often closely resemble terrestrial
plants, but as stated above are not plants, found among
the green, red, and brown algae. These and other algal
groups also include various single-celled creatures and
forms that are simple collections of cells, without
differentiated tissues. Many can move about, and some |

Aquarium
( Added: Fri Jan 13 2006 Hits: 110)
|
| An aquarium (plural aquariums or aquaria) is a
clear-sided container (typically constructed of glass or
high-strength plastic) in which water-dwelling plants and
animals (usually fish, and sometimes invertebrates, as
well as amphibians, marine mammals, and reptiles) are
kept in captivity, often for public display; or it is an
establishment featuring such displays. Aquarium keeping
is a popular hobby around the world, with about 60
million enthusiasts worldwide. From the 1850s, when the
predecessor of the modern aquarium was first developed
as a novel curiosity, the ranks of aquarists have swelled
as more sophisticated systems including lighting and
filtration systems were developed to keep aquarium fish |

Basking Area
( Added: Fri Jan 13 2006 Hits: 111)
|
| The water turtle must be able to dry it's shell to prevent
fungus and bacterial attacks. This is one reason they
bask in natural sunlight in the wild. The basking area in
an aquarium can be a large branch that extends out of
the water or a secure pile of rocks large enough to afford
a high and dry area. Floating plastic islands and lily pads
are available but may not support the turtle sufficiently to
allow it to get completely out of the water and dry out. A
solid basking area is preferred. If kept indoors, a light
with sufficient UV energy, such as Repti-Sun 5, is helpful. |

| Biological loading is a measure of the burden placed on
the aquarium ecosystem by its living inhabitants. High
biological loading in an aquarium represents a more
complicated tank ecology, which in turn means that
equilibrium is easier to perturb. In addition, there are
several fundamental constraints on biological loading
based on the size of an aquarium. The surface area of
water exposed to air limits dissolved oxygen intake by the
tank. The capacity of nitrifying bacteria is limited by the |

| Public aquaria are facilities open to the public for viewing
of aquatic species in aquaria. Most public aquaria feature
a number of smaller tanks, as well as one or more large
tank greater in size than could be kept by any home
aquarist. The largest tanks hold millions of U.S. gallons of
water and can house large species, including dolphins,
sharks or beluga whales. Aquatic and semiaquatic
animals, including otters and penguins, may also be kept
by public aquaria. |
