How to put filter equipment in fish tank
In fish farming, the filtration system is key to maintaining healthy water quality in the fish tank. Reasonable placement of filter equipment can not only improve filtration efficiency, but also extend the service life of the equipment. This article will introduce in detail how to place fish tank filter equipment and provide structured data for reference.
1. Classification of fish tank filter equipment
Fish tank filtration equipment is mainly divided into three categories: physical filtration, biological filtration and chemical filtration. The specific equipment is as follows:
| Filter type | Common equipment | Function |
|---|---|---|
| Physical filtering | Filter cotton, magic carpet | Intercept large particles of impurities such as fish feces and leftover bait |
| biological filtration | Ceramic ring, bacteria house | Cultivate nitrifying bacteria to decompose harmful substances |
| chemical filtration | Activated carbon, protein cotton | Adsorb pigments, drug residues, etc. |
2. The order of placing filter equipment
The correct placement order can maximize the filtering effect. The following are recommended water flow paths and equipment placement:
| water flow direction | Recommended equipment | function |
|---|---|---|
| first floor | Coarse hole filter cotton | Block large particle impurities |
| second floor | Fine-pore filter cotton or magic carpet | Further filtering fine particles |
| third floor | Biological filter material (ceramic ring, etc.) | Provide an environment for the growth of nitrifying bacteria |
| fourth floor | Chemical filter materials (activated carbon, etc.) | Adsorption of dissolved impurities |
3. Placement of equipment for different filtration systems
Common filtration systems in fish tanks include top filters, bottom filters, filter barrels, etc. The equipment placement of different systems is slightly different:
1. Upper filtration system
Upper filtration usually has limited space. It is recommended to prioritize physical filter cotton and a small amount of biological filter material. Chemical filter material can be added selectively according to water quality conditions.
2. Bottom filter system
The bottom filter has a large space and can be placed in layers:
3. Filter barrel system
The filter barrel usually adopts the sequence of "water inlet → physical filtration → biological filtration → water outlet", and the chemical filter material needs to be placed separately in the filter basket.

5. Frequently Asked Questions
| question | Answer |
|---|---|
| How often should the filter cotton be replaced? | It is recommended to replace or clean once a month, depending on the degree of dirt. |
| Does biological filter material need to be cleaned? | Clean 1-2 times a year and rinse lightly with original tank water. |
| How long does activated carbon last? | It usually expires in 3-4 weeks and needs to be replaced in time. |
By properly placing filtering equipment, the water quality of the fish tank will be more stable and the fish can grow healthily. It is recommended to check the filtration system regularly to ensure it is operating efficiently.
