A spherical airstone at the Osaka Aquarium alongside a trio of red stingray pups, Hemitrygon akajei. An airstone, also called an aquarium bubbler, is a piece of aquarium furniture, traditionally a piece of limewood or porous stone, whose purpose is to gradually diffuse air into the tank, eliminating the noise and large bubbles of conventional air filtration systems, and providing other ...
The use of shallow water is also because fertilized eggs need to be aerated in order to hatch successfully. [3] Various stimuli have been shown to affect onset the construction of bubble nests, such as rapid changes in temperature, barometric changes, fluctuations in rainfall, various fish tank materials, and presence of other males or females.
Additionally, smaller bubbles take more time to reach the surface so not only is the surface area maximized but so are the time each bubble spends in the water, allowing it more opportunity to transfer oxygen to the water. As a general rule, smaller bubbles and a deeper release point will generate a greater oxygen transfer rate. [9]
In aeration air is pumped through an air stone or similar device that creates small bubbles in the water column, this results in a high surface area where oxygen can dissolve into the water. In general due to slow gas dissolution rates and the high air pressure needed to create small bubbles this method is considered inefficient and the water ...
Gas bubble disease is a disease of fish that are exposed to water supersaturated with natural gases like oxygen, carbon dioxide, or nitrogen. [1] Bubbles of gas may form in the eyes, skin, gills , and fins. [ 2 ]
diving at altitude – diving in water whose surface pressure is significantly below sea level pressure – for example, Lake Titicaca is at 3,800 m (12,500 ft). Versions of decompression tables for altitudes exceeding 300 m (980 ft), or dive computers with high-altitude settings or surface pressure sensors may be used to reduce this risk.
A bubble curtain in Florida used to stop debris entering the marina. A bubble curtain is a system that produces bubbles in a deliberate arrangement in water. It is also called pneumatic barrier. The technique is based on bubbles of air (gas) being let out under the water surface, commonly on the bottom.
The goal of quarantine is to prevent problems in the main tank due to sickness. A quarantine tank should be used before to introduce any newly acquired animals in the main tank and to treat fish that are already sick. By doing this, the aquarist can avoid the spread of the disease and make it easier to treat the fish. [1]
