What kind of filters do you put in your aquarium?

A good filter not only ensures the growth of fish, but also beautifies the aquarium. In the purchase, fish tank filter which is good? The following is a recommendation for you ten kinds of aquarium filters.

Which is a good fish tank filter? Recommended for you ten kinds of aquarium filters ~

One, the top of the tank filter (upper filter)

The pump that drives the top of the tank filter can be a "dry" or "submersible" water pump.

1, through the "dry" pump driven tank top filter, this tank top filter is usually sold with the filter box, the pump is placed on top of the water surface, the water is pumped out through the sink, the sink is placed in the filter material, the opening under the sink, the filtered water flows back into the tank.

2, through the "submersible" pump driven tank top filter, as the name suggests, is the pump in the water underwater, plus an upper filter box or the upper part of a variety of filtration materials and biochemical materials containers. The way of filtration and through the "dry" pump driven tank top filter is basically the same.

Second, built-in biochemical filter in the upper layer of the tank

Changed "submersible" pumps, after the internal structure of the modification, through the "submersible" pump water inlet plus filtering materials, to achieve the purpose of filtration. The water can be absorbed in the upper layer of water and filtered through the filter material installed inside. The upper built-in biochemical filter is designed with an oil film removal device on the surface of the water, which removes the oil film and improves the transparency of the water surface. This filter makes full use of both physical and biochemical filtration methods to remove dirt from the aquarium, enhancing the filtration effect and ensuring clear water quality. It is generally applicable to 40-80cm small and medium-sized aquariums.

Three, built-in biochemical filters

Similar to the built-in biochemical filters in the upper part of the tank, the filter material is added to the inlet of the submersible pump to achieve the purpose of filtration. It is easy to install and the filter material is high quality with good hydrophilicity. Characteristics: It is the same as the built-in biochemical filter in the upper layer of the tank except that it does not have the function of sucking out the dirt on the surface of the water. However, the power of the pump is bigger and the range is higher.

Four, the bottom of the tank biochemical filter

is also a variant of the "submersible" pump. Through the submersible pump and porous plastic biochemical filter plate combination, through the bottom of the biochemical filtration cycle. Can be laid into the biological ring and bacterial filter cotton, can also be composed of several layers of different sizes of gravel layer, smaller particles of gravel in the top layer, the larger particles placed at the bottom of the water will be discharged from the bottom of the plate through the pipeline located in the bottom of the plastic plate, the laying of the filter material or gravel are designed to propagate the beneficial digestive bacteria.

Fifth, waterfall filter

Waterfall filter, more suitable for small square tanks, longer tanks will make the water flow is very messy, can not filter clean sediment bottom of the tank debris. If it is a grass tank is not suitable for this kind of filter, too much waterfall will make the algae grow faster, affecting the beauty of the tank.

Sixth, external biochemical filter

The "submersible" pump and the external filter bucket are set outside the tank, the water in the tank first flows into the bucket, the bucket contains double or multi-layer filter box, and the filter and nitrification materials are placed inside the bucket, the filter pump pumps the water in the bucket and circulates the water through the tubes into the tank. Other filter materials can be purchased according to specific requirements.

Seven, external biochemical filter (tank hanging)

The principle is the same as the external biochemical filter, but the size of the filter bucket is smaller, so it can be hung on the outside of the tank.

Eight, outside the tank biochemical filtration system

Can be installed according to the size of the tank, the use of various filter media and multi-channel filter bucket, so that the water is fully filtered, more suitable for large aquariums, the filter bucket can be purchased off-the-shelf, according to the size of the tank around the location of the design of the corresponding filter bucket or filter tank, many people like DIY friends to use this filtration system.

Nine, dissolved oxygen biofilter

need to work with the air pump, the air pump as power, does not take up space in the fish tank. It can be used as a biological filter for small fish. It can also be used as an auxiliary filter for medium and large fish tanks to help stabilize water quality and increase dissolved oxygen. It can produce fine air bubbles, can replace the bubble stone, both oxygenation and filtration in one, the air holes are completely interoperable, the contact area of the filter cotton is large, it has excellent biological filtration effect, and it can be used for the growth of a large number of nitrifying bacteria. It is most suitable for breeding and hatching fish.

Ten, wall-mounted multi-functional fish tank

No water change aquarium biological purification and treatment devices and filtration and oxygenation devices combined by the water curtain filtration and oxygenation tanks, bottom grille, circulation pumps and pipelines, the filtration and oxygenation tank is located in the water above the bottom of the tank has a number of curtain leakage holes, the bottom grille is located at the bottom of the cylinder, the corresponding grille at the end of the side of the tank to the filtration and oxygenation tank by the circulating pumps and pipeline connection

The fish tank filter is too large to be connected with the filter.
