    It holds 7,500,000 litres (1,981,000 US gal) of water and features an acrylic glass panel measuring 8.2 by 22.5 metres (27 by 74 ft) with a thickness of 60 centimetres (2 ft), [34] the largest such panel in the world when the aquarium was opened. [4] [35] Whale sharks and manta rays are kept alongside many other fish species in the main tank. [4]

  4. Aquarium filter - Wikipedia

    en.wikipedia.org/wiki/Aquarium_filter

    Air-driven corner filter. Aquarium filters are critical components of both freshwater and marine aquaria. [1][2][3] Aquarium filters remove physical and soluble chemical waste products from aquaria, simplifying maintenance. Furthermore, aquarium filters are necessary to support life as aquaria are relatively small, closed volumes of water ...

    en.wikipedia.org/wiki/Reef_aquarium

    A nano reef is a type of marine aquarium that is typically less than 140 litres (30 Imperial gallons / 37 US gallons). The exact limit that distinguishes a nano reef from a regular reef is somewhat ill-defined. Some claim that anything less than 180 litres (40 Imperial gallons / 48 US gallons) would qualify.

    Many color and tail pattern varieties exist. They generally need a ratio of 1 male to 2 females or more. All guppies and mollies are hardy fish that tolerate lower oxygen levels and temperatures than most aquarium fish, give birth to live young, and readily breed in home tanks. [58] can live in full sea water [59] 66°F - 84°F (19°C - 29°C ...

    en.wikipedia.org/wiki/Darcy_friction_factor_formulae

    Churchill equation [24] (1977) is the only equation that can be evaluated for very slow flow (Reynolds number < 1), but the Cheng (2008), [25] and Bellos et al. (2018) [8] equations also return an approximately correct value for friction factor in the laminar flow region (Reynolds number < 2300). All of the others are for transitional and ...

  9. Total internal reflection - Wikipedia

    en.wikipedia.org/wiki/Total_internal_reflection

    Fig. 1: Underwater plants in a fish tank, and their inverted images (top) formed by total internal reflection in the water–air surface. In physics, total internal reflection (TIR) is the phenomenon in which waves arriving at the interface (boundary) from one medium to another (e.g., from water to air) are not refracted into the second ("external") medium, but completely reflected back into ...
