How to use fish tank filter pump
The fish tank filter pump is an important equipment to maintain clean water quality and ensure fish health. Proper use of a filter pump will not only extend the life of your equipment, but also improve the stability of your fish tank ecosystem. This article will introduce in detail the use of fish tank filter pumps, common problems and solutions, and provide you with a practical guide based on hot topics on the Internet in the past 10 days.
1. Basic functions of fish tank filter pump

The main function of the filter pump is to remove impurities and harmful substances in the fish tank through physical and biological filtration, while promoting water circulation. The following are the three core functions of the filter pump:
| Function type | function | Example |
|---|---|---|
| Physical filtering | Intercept visible particles (such as fish feces, residual bait) | Filter cotton, sponge layer |
| biological filtration | Cultivate beneficial bacteria to decompose harmful substances such as ammonia and nitrite | Ceramic ring, bacteria house |
| water cycle | Increase oxygen content in water and avoid stagnant water areas | Outlet flow creation |
2. Installation steps of filter pump
Here is a step-by-step installation guide for most submersible pumps or external filter pumps:
| steps | Operating Instructions | Things to note |
|---|---|---|
| 1. Choose a location | The submersible pump should be placed at the bottom of the fish tank, and the external pump should be connected to the inlet and outlet pipes | Avoid decorations to prevent clogging |
| 2. Connect the filter media | Fill the filter tank in the order of "Physical → Biological" | Biological filter material needs to be soaked in advance |
| 3. Power on test | Check whether the water flow direction and flow rate are normal | There may be bubbling sounds during the first run. |
| 4. Adjust flow | Control the intensity of water flow through valves or gears | Low flow rate is recommended for small fish tanks |
3. Answers to recent popular questions (based on discussion data from the entire network within 10 days)
Combined with recent hot topics, the following are the 5 issues that aquarists are most concerned about:
| Ranking | question | solution |
|---|---|---|
| 1 | Filter pump is too noisy | Check whether the vibration contacts the cylinder wall, or clean the rotor to accumulate dirt. |
| 2 | Strong water flow affects fish | Install a rain shower pipe or adjust the direction of the water outlet |
| 3 | Frequent blockage | Pre-coarse filter cotton, clean once a week |
| 4 | High power consumption | Choose an inverter model and turn down the gear at night |
| 5 | Unable to restart after power outage | Check whether there is air intake. Manual water injection is required to drain the air. |
4. Maintenance cycle recommendations
Regular maintenance is the key to ensuring filtration efficiency. Please refer to the following schedule:
| maintenance items | Frequency | Operational points |
|---|---|---|
| Cleaning physical filter media | 1 time a week | Rinse with original tank water to avoid killing nitrifying bacteria |
| Check the pipes | 1 time per month | Remove algae or calcification |
| Replace rotor lubricant | every six months | Use special silicone grease |
| Comprehensive disinfection | 1 time per year | Soak in 5% citric acid solution |
5. Recommendations for purchasing popular models (e-commerce platform data in the past 10 days)
Cost-effective models organized according to sales volume and positive reviews:
| Model | Suitable for fish tanks | Features | reference price |
|---|---|---|---|
| Sensen JTP-1800 | 100-200L | Frequency conversion, energy saving, silent design | ¥159-189 |
| Chuangxing AT-306 | 60-120L | Strong corrosion resistance | ¥85-110 |
| Boyu BY-350 | 30-50L | Ultra-quiet, with degreasing film | ¥65-79 |
Through the above structured guide, you can not only quickly master the use skills of filter pumps, but also choose the appropriate equipment according to the latest market trends. Remember:Good filtration system = regular maintenance + reasonable configuration + observation and adjustment, wish your aquatic world is clear and healthy!
