We all know that fish first water, but to raise a tank of good water, the necessary equipment is indispensable, that the necessary equipment are what?

Today I gathered for you to summarise a very practical introduction to common aquarium equipment and the use of strategy, I hope that the fish friends can be on the road to fish less detours, everyone can raise a tank of good water, a tank of good fish. (The article is a little long, please be patient to read the article, I believe it will solve your aquarium filtration system of some confusion!)

1. Upper Circulation Filtration (Upper Filter)

Upper filter is placed in the upper part of the aquarium, through the submersible pump will be pumped into the upper filter tank, the water flow through the filter cotton, biochemical cotton, a variety of filter media and then by the bottom of the outlet pipe flows back into the aquarium.

Advantages: low price, simple structure, easy to clean and maintain.

Disadvantages: occupy the upper space of the aquarium, to a certain extent, affecting the aesthetics of the aquarium, the internal space is limited to place the filter material is relatively small so that the biochemical filtration effect is general. In addition, due to the upper filtration water area will increase the escape of CO2, so it is not suitable for planting aquariums.

2、Drip filtration (drip filtration)

Drip filtration is an integrated filter, it will be physical filtration and biological filtration in a filter tank, in this filter tank is divided into several layers, (the specific number of layers can be increased or decreased according to the needs of) the upper layer of the filter tank for the physical filtration chamber, the main placement of the filter cotton, biochemical cotton, the following layers were placed in the biochemical ball, rattan cotton, glass ring, quartz ball, bacteria house and other filter materials. When the water flow through will increase the contact surface with the air to increase the oxygen capacity, for aerobic bacteria to provide the most ideal living environment.

Advantages: Perfect physical and biochemical filtration, good filtration effect.

Disadvantages: It also takes up space in the upper part of the aquarium, affects the aesthetics of the aquarium to a certain extent, and the sound of the water flow is relatively large.

3、Back filter and side filter

Back and side filtration is in the back or side of the aquarium with a glass partition part of the filtration, the interior is divided into several small compartments for placing the filter material and circulating pumps, one side with an overflow port, when the pump pump pumps water from the filtration part of the aquarium, the aquarium overflow of water through the overflow port into the filtering part of the first compartment, guided by a variety of filter material flows through the partition, the water from the last compartment through the pump again into the aquarium to form a cycle.

Advantage: Using the inner space of the aquarium to make the aquarium and filtration form an integral whole, without the need to use other outside the aquarium to complete a better filtration process. Some equipments can be placed in the side/back filtration, properly placed without affecting the visual aesthetics of the front of the tank.

Disadvantages: Taking up some space in the tank, the space inside the tank will be reduced, limited by the width or length of the tank, the placement of filtering materials is also limited, the evaporation of water will cause the water level in the interval where the pump is located to decrease faster, requiring frequent replenishment.

4、Bottom tank filtration

Bottom tank filtration is to use a large filter tank placed in the bottom cabinet (known as the bottom tank), connected to the main tank through the pipeline, using the pump to complete the water cycle, the filter tank is divided into a number of compartments according to the size and the actual need to be used for placing different filter materials or equipment, the bottom tank filtration is generally used in the overflow of the water, in the form of a triangular overflow, square overflow, round overflow, triple overflow pipe overflow, overflow, non-perforation And many other forms.

Advantages: Physical and biochemical filtration perfectly match, increase the water body of the whole system, more conducive to maintaining stable water quality. More space in the bottom tank can put more filtering materials. There is more space in the bottom tank to put all kinds of equipments, which makes the main tank more neat and beautiful. Water change and other operations can be carried out in the bottom tank, effectively reducing the impact on the organisms in the tank.

Disadvantages: The water level of the main tank is not easy to mediate, the structure is complicated, the production cost is high, improper water mediation is easy to produce noise, easy to cause humidity in the bottom cabinet, the pump head will become longer power will also increase accordingly, and the power consumption will also increase.

5、Outside filter bucket filtration

External bucket filtration is a closed form of filtration, the barrel is divided into a number of internal layers, each layer can be placed on different filtering materials, the use of barrels or barrels outside the pump so that the water in the aquarium continues to flow through the barrel of the various layers of filtering materials, so as to achieve the purpose of cyclic filtration. Before starting, make sure the bucket and the inlet and outlet pipes are full of water to avoid air accumulation.

Advantages: takes up less space in the tank, lower noise, good biochemical filtration effect, more flexible installation, the water can help to create a flow.

Disadvantages: weaker physical filtration effect, more cumbersome to clean and start, inlet and outlet pipes are easy to cause clutter.

6、Hanging filter (waterfall filter)

The external filter is a kind of semi-enclosed filter hanging on the wall of the tank, with different filter materials placed in the internal area, using the pump that comes with the body to draw the water inside the aquarium into the internal filter and flow through the various filter materials, to achieve the purpose of cyclic filtration.

Advantages: low price
