Types and characteristics of the filter

Aquarium keeping filtration system is the key equipment, is to maintain quality and stability of the most important aspect, therefore, to understand the content filtering system is necessary. Filter by location on the aquarium, filter functions and objects can be divided into the following types: RI `= M_L`??
    (1) pipe filter at the bottom of the filter aquarium filter plate located at the bottom of the board left plugged up the holes snorkel, plug in plastic pipe. Laying gravel filter plate above (coral sand, shells, sand may be). Inflatable plastic tube connected to the pump, when inflated, driving water flow through the gravel, on the one hand inflatable oxygenation, on the one hand to achieve the effect of filtering. There is also a sand bed of the filter set in the aquarium, the water pump or pump the water to the filter, the filter and then returned to the aquarium. Y:. /? ISi;
    At the bottom of the filter separator material requirements hard, have a certain tolerance, chemically inert, does not react chemically in the water and pollute the water. There seepage microporous separators, filtration size of the hole in the water can seep through the sand can not be appropriate. Br cfzQ? N
    Filter sand bed of filter sand material should be selected hard, chemically stable gravel, such as quartz sand, river sand. Sand should be uniform in size, irregular shape, slightly rough surface, a diameter of 3 to 5 mm, this will increase the adhesion area of ​​nitrifying bacteria. ** PrkWJ? F2
    From precision filter effect, the sand bed area the better. The depth of the sand filter should not be too deep or too shallow. Nitrifying bacteria in the sand bed surface and bottom of the distribution to more middle small. Nitrification occurs mainly in the surface 5 cm sand bed (90%), 10 cm below the bottom part is usually no nitrification. Therefore, the filter sand bed depth of 6 to 10 cm is appropriate. i0L & PE?

    The disadvantage is that the bottom of the filter weight and bulky, inconvenient to change the water and clean gravel, plants are particularly vulnerable to damage the roots. Rm.? XgV \ h
    (2) the upper basket filter aquarium filter placed in the top of the water is pumped to the filter in the filter. This filter is rectangular, putting carbon or biochemical filter balls, the top layer of filter cotton combined into the water layer filter layer. When switched on, the aquarium water is suction filter box, then back into the aquarium through the filter layer. Should be based on the turbidity of the water quality regularly clean the filter material, the filter layer to prevent the gap due to the accumulation of excess dirt and affect the water circulation and filtration. Upper filter is not set oxygen equipment, noise is small, clean fish tank is very convenient, but the resulting filter is slightly less than the bottom of the nitrifying bacteria filter, filtration space is small, the number of fish can not be too much. ?

    (3) Gas filters External filters have filter hanging outside the lower overflow filters and filters immersed other forms. External hanging filter is the filter device hanging on the side or top of the aquarium, the submersible pump pumping the water into the filter tank, filtered through filter back into the net after the aquarium. This filter is easy to clean, easy to use, but difficult to grow nitrifying bacteria, filtering function far better than at the bottom of the filter, it is best to use a combination of both. q +% dgG =%!
    Aquarium filter is installed in the lower part of the lower part of the upper pipe is connected with the aquarium, the lower space, can magnify the area of ​​the filter, putting a variety of efficient filter material. Dip overflow filters are not commonly used. M TOTw] LWj
    (4) liquid filter called sink water filter. The device into the water, the use of submersible pump water directly into the filter tank, through the filter on the tank filter and filtered back into the aquarium nitrifying bacteria. Containing filter material is a closed and pump combinations. Such filters, small size, low noise, limited space occupied by the aquarium, easy to manage, and assembly and maintenance, but the handling of water and filter cleaning interval is shorter, only for smaller aquarium.

    (5) trickle filter The principle is: the aquarium water from the upper, middle and lower three parts, respectively, into the overflow tube (also known as the aquarium and positioning drain pipe) and into the following filter slot. Filter material from top to bottom: a biochemical filter cotton ball a sand-water storage tank (can be put ozone generator, UV germicidal lamp, protein skimmers, etc.) a small bag of activated carbon. Trickle filter multi-channel multi-layer (physical, biological, chemical) filtration, filter effects, and in the saltwater aquarium filtration system widely used. ? KQ? Ru? V??
    (6) refers to a mixture of different filters filter combination. Such as an external filter in combination with the built-in filter, at the bottom of the filter in combination with external filters and so on.
