How much do you know about how the filter elements in the fish tank work

I believe that the friends who often feed ornamental fish are familiar with the filter. What we usually come into contact with is nothing more than the filter cotton, biochemical cotton and glass ring and other common filter substances. Then, in addition to these, there are other filter materials? Xiaobian this for you to introduce several. Biosphere is an important filter element in fish tank. Biosphere is mostly spherical or irregularly shaped, made of plastic, and has many protruded holes on its surface. Biochemical ball is a kind of use a biological filter material, but the use scope is extremely limited, its special structure can not be used in many filtering methods, generally applicable is in the drip air filter, try not to take the biochemical ball when use the bubble in the water, but to make the water from above, a large number of flows, bring more air, parasitic more nitrifying bacteria, In order to achieve a good filtering effect, but to ensure the use of multiple biospheres at the same time to see good results. Volcanic rocks Volcanic rocks, as the name implies, is due to the eruption of lava cold, rapid cooling, forming crystals, these crystals are usually relatively small, some magma crystallization and the formation of vitreous, containing a large amount of gas emanating from the inside of the rock to form a number of circular holes. The pores of these volcanic rocks are closely connected, and they are highly resistant to corrosion. There are a large number of cracks in the interior, which provides a natural environment for nitrifying bacteria to implant. Coral sand is formed by the accumulation of the dead bones of coral polyps over many years. When polyps die, they leave many small pores, which are generally compact and more permeable than other materials. Its internal structure is more suitable for nitrifying bacteria, which can filter impurities in the water as it passes through. Medical stone Medical stone internal contains a variety of beneficial soluble trace substances, before people usually put medical stone in drinking water equipment, in foreign countries are applied to aquarium filtration system, to regulate water quality. Medical stone can adjust the PH value of medium (PH), sometimes released a large number of trace elements, the hatching of young fish is more good, usually placed in the position of the glass ring. Ammonia-absorbing zeolite contains a variety of trace elements, can quickly adsorption water nitrite and ammonia ions and other toxic substances, and can stabilize the PH value, to provide a more suitable environment for fish to live. The above 5 kinds of filtration materials are biochemical filtration, but to ensure the clear water quality in the aquarium, biochemical filtration is not enough, in addition to the corresponding physical wire mesh filtration, in order to achieve the ideal purification effect.
