What is a Power Filter in an Aquarium?
A power filter is hanging style model that uses a pump to circulate aquarium water through the system then return it to the tank.
It uses a lift tube to pull the water out of the tank and into a filter chamber where it is pushed through various filter media. The stages of filtration vary by model.
Generally, though, there will be mechanical, chemical, and biological filters that will eliminate toxins and debris from your aquarium.

Aquarium Power Filter Reviews
1. AquaClear Power Filter – 110 V
The AquaClear Power Filter is one of the most versatile on the market. It comes in five different models and is compatible with most popular aquarium sizes.
You can control the flow rate of the filter without changing how effective it is. This is a great feature because different fish and aquarium plants need a gentler flow. When you set the rate low, the water inside the filtration system is processed multiple times. This patented re-filtration system provides optimal results.
With some filtration systems, the beneficial bacteria are thrown away with cartridge changes. This can stress the aquarium environment until the bacteria has a chance to recolonize and get back to work. The AquaClear Power Filter is designed with that in mind.
This filter actually uses three different media for filtration. At the bottom of the canister is a foam insert, which removes debris and provides an ideal surface for beneficial bacteria to thrive to keep the water colonized. The middle layer is activated carbon that soaks up any impurities found in the water.
The top layer consists of BioMax, designed with a pore system that provides a perfect home for beneficial bacteria. These layers combined provide six times the amount of media as other filters.
AquaClear offers a lifetime warranty on any non-replaceable parts.
- Six times the filtration media of other filters
- Lifetime warranty
- Comes in several different sizes suitable for different aquariums
- Changing filter media can be a hassle
2. Fluval C Power Filter
The Fluval C Power Filter gives amazing results thanks to its 5-stage filtration system. The media has a large surface area and optimal dwell times to ensure an effective filtration process.
Stages 1 and 2 of the filtration are a poly and foam pad. These layers combined perform the mechanical filtration, removing both large and small particles and debris.
Stage 3 consists of an activated carbon insert and performs chemical filtration. This will remove impurities, odors, and any discoloration from the water.
Stage 4 is the biological filter, a screen that sits on the Trickle Chamber cover. Water is filtered through the BioScreen from an additional hydraulic circuit. Debris is removed and the water goes back into the biological chamber.
Stage 5 is made of C-Nodes. They have a surface covered in complex pores that allows the beneficial bacteria to thrive so that it can continue removing ammonia and nitrates from the water.
This filter has a re-filtration system in place if you need to slow down the water flow for the benefit of any fish or plants that need a calmer environment. Even though the water is moving out of the tank slower, it’s being filtered multiple times before returning to the tank. This assures that the water remains clear and clean.

What is the Best Aquarium Power Filter?
The AquaClear Power Filter – 110V is the best aquarium power filter we reviewed. It’s very versatile and comes in 5 different sizes so it will fit just about any tank. It allows you to adjust the flow rate in case you have plants or fish that need a lower flow.
The three different filtration media used in this filter are really effective. The foam insert removes large debris, the middle carbon layer soaks up the invisible impurities, and the BioMax filter provides the perfect home for all the good bacteria you need to keep your tank nitrate and ammonia free.
What puts makes this the best power filter it the way it’s designed so that it preserves the natural bacteria colonies. With most filtration systems, changing the cartridges or cleaning the filters wipes out the good bacteria and it can take some time for them to grow again. During this time, the environment inside the aquarium will be stressed which will affect your fish.
Because it preserves these colonies, the AquaClear Power Filter is a little bit ahead of the rest.
How Does a Power Filter Work?
A power filter hangs on the back or side of your aquarium. While each model looks a little different, they all basically work the same way.
A lift tube sits in the water which the pump uses to pull the water up and out of the tank. The water then enters a filter chamber where it is pushed through various types of filter media. The stages of filtration vary by model. Some will provide as many as 5 different stages. Generally, though, there will always be mechanical, chemical, and biological filters.
Mechanical filters remove larger particles and pieces of debris. Chemical filters remove any impurities, odors, or cloudiness form the water. Biological filters allow good bacteria to thrive so that they can remove nitrates and ammonia from the water.
These good bacteria are essential to the health of the aquarium. It’s beneficial to the water, plants, and fish and will not change the way the aquarium looks. The water will remain clear and the plants and animals living inside will thrive.
How to Install Power Filter in Aquarium?
Installation will vary depending on the model and brand so make sure you look at the manual for complete, specific instruction. That said, there are some basic steps to installing your power filter.
First, examine the filter when you remove it from the packaging. Make sure that you have all the pieces and that there aren’t any cracks anywhere in the system. Once you’ve inspected it, place the filter box on the back of your aquarium.
Next, rinse the filter media. This is especially important for any carbon filters because it moves the carbon around, cleans out any loose bits, and ensures effective contact with the water after installation.
Install the intake tube. It should sit toward the bottom of the tank, about an inch or so about the gravel. Usually, you can cut the tubing to allow it to sit at the proper height.
Fill the filter box with water. Once everything is ready, plug in the filter. It will take a few seconds for the filter to get optimal flow.
Again, make sure you check your owner’s manual as each model and brand is a little different.
How to Clean Aquarium Power Filter?
The specific cleaning and maintenance method will depend on the model and brand. You should be able to find detailed instructions in the manual included with your filter.
No matter what kind of filtration media you’re using, it will need to be cleaned by rinsing them to remove any debris that’s built up. Eventually, you will need to replace each filtration media.
If your filter includes a sponge, you should be able to just rinse them in the aquarium water as needed. Only when they start to show signs of breakdown or wear and tear do they need to be replaced.
Carbon media should be replaced frequently to keep the water toxin free. If you need to add any medication to the water to treat your fish, remember to remove the carbon filter first.
If you leave it in, it will filter out all the medicine, meaning the tank won’t get treated and the filter will need replacing all that much sooner.
You will also need to clean the tubing and pump occasionally as they can stop working properly if too much debris builds up.
Finding the best power filter aquarium will help keep your aquarium water healthy and clear. They provide the essential mechanical, chemical, and biological filtration your plants and fish need to thrive.
