The direction of flow varies depending on the models and canister filter brands. Knowing the best aquarium canister filters helps you protect your tank.

After the water passes through the filter media in your sealed canister, it flows back into the fish tank. Canister filters use water pumps for water movement as the system is sealed. Most canister filter models have built-in water pumps into the base. Some models require separate external water pumps. Therefore, be careful when choosing the most appropriate model of the best aquarium canister filters to use.

The purpose of cleaning the filters is to remove rotten or accumulated organic material without killing too many beneficial bacteria. Avoid using hot water to clean the filter. Don use bleach or soap as they kill beneficial bacteria.
Setting up media
It is the first thing water hits before entering the filter intake. Otherwise, you will end up with a dirty filter that is changed frequently. Don’t let the debris reach other media.
Follow the installation instructions on the label to ensure the media is correctly placed. When cleaning the media, don’t use tap water to rinse it and avoid stuffing sponges or floss to the point that it reduces water flow as it weakens the filter.
The cups are meant to hold airline tubes and keep the filter in place if it has heavy media like ceramic rings or gravel. Suction cuts ensure air stones remain at the bottom of the filter.
Use T-vales or gang valves
Regulate airflow using gang vales to increase or decrease the air being pumped into the filter. You can find the gang valves in the aquarium store. The valves are unnecessary if your air pump has more outlets. Get a T-valve when dividing airlines or to increase airflow as one tube won’t work.
Place the filter floss in-front of intake slits to allow water to enter the filter for biological filtration. If the sponge is worn out, replace it. Always replace the filter floss after two months. Squeeze the filter floss severally to get rid of debris and dirt once it loses the brown color. You can use the sponge in canister filters as they are useful biological and mechanical filtration tool. The sponge filters promote low flow-rate and currents, making it ideal for fish as they do not suck up any creatures.
The narrow tunnel creates suction which pulls water through aquarium filter. Water flow travels through the filter catching any debris along the way. Biological filtration is invisible to the eye and involves beneficial bacteria growing on the media surface. Beneficial bacteria provide clean water chemically and visually. Every box filter needs a small tank of 20 gallons at least.
Before binding this review, we have Frequently asked questions that we need to discuss. This section literally addresses most customer concerns in regards to aquarium canister filter. Well, let’s see what we got for you this time. Note: You can add your main concerns if not addressed by the review in this section.
It uses the airlift principle. Air enters the filter via rigid and soft air-line tubing into the air stone. The column of air leaves the air stone drawing water through the filter., past the biological media before exiting.
It is a type of filter that utilizes media as the bio-film to permit air movement. In the process it gives the tank an abundant source of oxygen for the aerobic bacteria to finish the nitrogen cycle efficiently. The filters remove debris and other materials to keep the water clean and clear.
Because it allows visual inspection and easy to maintain without disturbing your aquatic life besides, it has high water mechanical filtration due to high levels of water circulation.
It mainly depends on the condition of your aquarium. Factors such as fish type, feeding schedule, fish size, frequency of water changes, and the number of fish, play a part in deciding the cleaning schedule. So, it can be weekly or monthly.
Remove the canister filter from the tank then rinse every component. Use water to rinse the sponge and bio media. Repeat the process until it is clean, but don’t use tap water as chlorine in the water kills beneficial bacteria. Scrub the housing and end caps using a sponge. When finished, reassemble the filter.
Filters come in different sizes, models, brands, and colors. Choose a color that is most convenient for you.
No. It can lead to contamination of the water or getting debris into the water. Furthermore, you scare the aquatic life.
It depends on whether the bio media is cycled. If yes, you can add your fish at that time. If it is a brand new aquarium, hold off adding fish until the aquarium is fully cycled. Use test kits to help you determine if the aquarium is fully cycled.
As you have seen, aquarium canister filters are vital if you want to keep the fish tank healthy for the fish and other aquatic animals. The choice of an appropriate filter depends on various situations. By now, you can figure out the best canister filter that will serve you well and meets your expectations. Keep the water in the aquarium clear and clean to prevent any contaminants. If you have multiple filtration systems in the fish tank, ensure you alternate the cleanings to ensure that you don’t end up cleaning all at the same week. Create a regular cleaning schedule and abide by the routine.
