The fish tank filter is a key piece of equipment for maintaining the ecological balance of the aquarium.

This article will combine hot topics and hot content on the Internet in the past 10 days to give you a detailed introduction to the use of fish tank filters, and attach structured data to help you quickly master the operation skills.
1. Core functions of fish tank filters
Fish tank filters mainly purify water quality through physical, chemical and biological triple filtration methods. The following is a comparison of their core functions:
| Filter type | effect | Common filter materials |
|---|---|---|
| Physical filtering | Intercept visible impurities (feces, residual bait) | Filter cotton, fine mesh |
| chemical filtration | Adsorb dissolved harmful substances | Activated carbon, zeolite |
| biological filtration | Cultivate beneficial bacteria to break down ammonia/nitrite | Ceramic ring, bacteria house |
2. Comparison of popular fish tank filter types (TOP3 search popularity in the past 10 days)
| type | advantage | shortcoming | Applicable scenarios |
|---|---|---|---|
| External filter barrel | High filtration efficiency and quiet | higher price | Fish tank above 60cm |
| wall mounted filter | Easy to install and cost-effective | Limited filter space | small fish tank |
| water fairy | Oxygenation + filtration in one | Need to be used with air pump | Breeding tank/isolation tank |
3. Step-by-step usage guide
1.Installation preparation:Select the filter flow rate according to the volume of the fish tank (it is recommended that the circulating water volume per hour be 5-10 times of the total water body)
2.Filter material placement order(from water inlet to water outlet direction):
Physical filter cotton → biological filter material → chemical filter material (activated carbon, etc. are not necessary)
3.Routine maintenance cycle:
| maintenance items | frequency | Things to note |
|---|---|---|
| Clean physical filter cotton | 1 time a week | Rinse with original tank water |
| Replace chemical filter media | 1 time per month | Activated carbon needs to be replaced regularly |
| Check biological filter media | 1 time per quarter | Avoid extensive replacement |
4. Answers to recent hot questions
1.Water becomes cloudy after running new filter?
This is a normal "tank break-in period" phenomenon, indicating that the nitrification system is being established, and it usually returns to clarity in 3-7 days.
2.What should I do if the filter noise is too loud?
Check whether there is air intake (the external filter barrel needs to be filled with water), whether there are foreign objects stuck in the rotor, and whether it is padded with shock-absorbing cotton.
3.How to tell if the filter flow is insufficient?
Observe phenomena such as the accumulation of oil film on the water surface, frequent floating fish heads, and increased mucus on the surface of the filter material.
5. Purchasing suggestions (based on recent e-commerce platform sales data)
| price range | Recommended brands | Features |
|---|---|---|
| Below 100 yuan | Sensen HBL series | Adjustable water flow direction |
| 100-300 yuan | Chuangxing CF series | Double water inlet to prevent gas collection |
| More than 300 yuan | EHEIM Classic Barrel | Ultra-quiet design |
Through the above structured guide, you can not only quickly master the use of fish tank filters, but also choose the appropriate product according to your actual needs. Remember to maintain the filter regularly to keep your aquarium world clear and beautiful!
