What Is A Fish Tank Filter Cartridge?
Every aquarium water filter has filtering media inside: this is what ensures chemical, biological, and mechanical cleaning. From time to time, old dirty and clogged filtering media layers that come in cartridges should be replaced with new ones.
There are several types of filter cartridges depending on the type of cleaning performed:
- Mechanical (removes sand, debris, large particles);
- Biological (kills bacteria);
- Chemical (removes toxic chemicals, such as ammonia);
- Mixed (several types of media).

Tetra Whisper Replacement Carbon Filter Cartridges, Small, 6 Count
Review
If you have a small aquarium up to 5 gallons, this is the best fish tank filter package you can find. Cheap, ready to use, the filter does what’s said on the label. Thanks to the activated carbon, it removes odors and chemicals from the water, while the fine mesh catches debris. The 6-pack lasts for at least two weeks, if you have a large aquarium, though Tetra recommends changing filters once in a week. The set is designed for Whisper 1-3i filter system.

Purchase of this pack is justified for owners of small fish tanks. It lacks biological filter though, so be ready to buy additional media.
PROS
- Non-expensive;
- Easy to install;
- Removes odors and discoloration.

Frequently Asked Questions
Q: How To Clean A Fish Tank Filter Cartridge?
A: Cartridges are not cleaned – they are replaced after becoming clogged. However, the filter itself should be cleaned from time to time (for example, when you’re replacing the water in the fish tank).
Q: How To Install Fish Tank Filter Cartridge?
A: Rinse filter cartridge under cool tap water to remove the residues of carbon and other stuff. Open the filter’s lid and insert the cartridge inside after removing the old one.
Q: How Often To Change Filter Cartridge In Fish Tank?
A: Cartridges should be changed at least once in 4 weeks, however, it depends on a variety of factors including aquarium capacity and the quality of water. As a rule, clogged cartridges are replaced when there’s a decreased flow out of the water.
Q: How To Remove A Fish Tank Filter Cartridge?
A: Switch off the filter and open the filter’s lid. Pull a cartridge to remove it.
Q: What Does Filter Cartridge For Fish Tank Do?
A: It removes dirt, debris, chemicals, and odors from water eliminating the discoloration. Some filters also kill harmful bacteria.
Q: How To Replace Fish Tank Filter Cartridge?
A: Switch off the filter and open the filter’s lid. Pull a cartridge to remove it. Wash the filter, if necessary, and place the new cartridge by sliding it in the slot.
Q: Why do fish get stuck on the filter?
A:Commonly, it means that the filter is too powerful for your aquarium: it creates a too strong current that makes small fish stressed. Another possible explanation is an illness or weakness of this particular fish. Keep in mind that fish can get weak and sleepy due to a high ammonia level. If the problem is in the filter, the best solution is to decrease the power of filtration. If the flow can’t be adjusted, then you may try using a sponge sleeve on the intake tube. If this doesn’t help, you should consider replacing a filter.
Q: How long should a fish tank filter last?
A: How long a fish tank filter should last depends on its type. Generally, the vast majority of filter cartridges require changing once a month. The reason is the carbon present in all cartridges. It removes chemical substances from the tank water and eventually fills up with them itself. If you don't change the filter cartridge after a month, it will collect beneficial bacteria, which is good for the aquarium inhabitants, yet will stop removing chemical impurities. This will make the water improper for the fish to thrive. You should replace the filter media of an in-tank or a hang-on-back filter every three to four weeks, too. When doing it, clean the filter. The intake tube might have accumulated debris or algae which must be accurately cleaned, while the filter housing must be just rinsed.
Our Recommendations & Conclusion
How to select a filter cartridge fish tank option? It should mostly depend on the type of filter you use. The majority of cartridges are in nearly the same price range: you can get a 6-pack for $7, or a 3-pack for $3-4. Out of all reviewed models, we highly recommend Aqueon Replacement Filter Cartridges.

Is a bigger aquarium filter better?
hi,
In a nutshell, a bigger filter provides better filtration. That is why the more powerful a filter is the better. However, there is a seamy side to everything: a big filter creates a too strong current, which can be dangerous for small fish. This is why it makes sense to focus on the quality of filtration. Make sure the device provides decent biological filtration. Mechanical filtration is also important, while chemical filtration is not mandatory in many cases.
Fish are fantastic pets, but they’re not the cleanest animals on the planet. Whenever fish do their business, everything is left floating around in the tank for all to see. The best aquarium filters will make sure your water quality stays consistently well while your tank water looks crystal clear. This way, you’ll get to enjoy watching your little critters move around while also helping make sure their habitat is as friendly and livable as possible. There are filters built for every size, shape, and type of tank you cold imagine.
