How to Setup & Clean an Aquarium External Filter: Canister Filter:
External filters are located
outside of the aquarium. They use intake / outtake pipes for drawing water from
the aquarium & pumping water back to the fish tank. They don’t consume
space inside aquarium so fish have more space to swim around. They are usually located
inside the cabinet so hidden from the human eye.
Canister filter works by drawing
water from the aquarium. Dirty water will be pushed to the bottom of the
canister using an internal hose. Then it will rise upward through the filter
media, & clean water will be forced back to the aquarium.
In this article, I have explained: How to setup & clean an aquarium external filter.
How to Setup an External Filter: Canister:
I have bought a canister filter &
its baskets contain some media. But I noticed that the media is not enough to
fill the baskets so I will suggest you to add more media too. I only received
fine foam. Chemical filter media as well as bio media was available in the
filter basket.
In video below I have shown you how to setup an external aquarium filter:
Step 1: Open the Lid of the Canister Filter:
Remove the lid from the filter. See the screws that are holding them together. If you can’t see them then have a look at the filter instruction manual. Then open the screws to remove the lid from the filter body.
After opening the screws, it is time to safely remove the filter lid. After separating the lid, you will see filter baskets that are located just below the lid. Filter baskets are holding the media that are used for cleaning water.
Step 2: Take Out the Baskets:
Open the canister filter &
take out every basket. Use coarse, medium & fine foams as mechanical filter
media. I have added cycled media from one of my tanks because cycled bio media
consists of lots of good bacteria. I would recommend adding aquapro booster
balls if you don’t have cycled media because it will boost the building up of good
bacteria.
Step 3: How to Setup Inflow / Outflow Bars:
It is easy to install intake
& outtake pipes of the canister filter. Have a look at the picture above if
you want to install pipes. Inflow pipe is used for drawing dirty water from the
aquarium. A strainer will stop the small fish. But if you want to setup canister
filter in fish fries or shrimp’s aquarium then use a sponge at the filter
intake that will stop the fries from entering the filter intake. When water is
filtered, then it is sent back to the aquarium with the help of a hose attached
to a spray bar.
Step 4: Stuff that Comes with the Canister Filter:
Canister filter comes with the
following components:
- 4 Baskets
- Fine foams for mechanical filtration
- 2 varieties of bio media for biological filtration
- 1 activated carbon that is used for chemical filtration
- Intake / outtake bars
I have used 3 types of foams such as coarse, medium & fine foams to crystal clear water. I have removed chemical media from the filter basket because I am not using it. I have used 3 different types of biological media for removing toxic chemicals from the water.
Step 5: Connect Hose to Inflow / Outflow Connectors:
Use a hose at the inlet of the
canister. Use a separate hose for the outlet of the filter that will push water
back to the aquarium. Water inlet hose will suck water from the fish tank.
Water will be pushed to the bottom of the filter & then it will rise upward
through the media, & clean water will be forced back to the tank.
Step 6: 1st Basket of the Canister Filter:
My filter comes with fine foams
only but I replaced them with three types of foams: coarse, medium & fine. All
foams go into the first basket of the filter. Mechanical filter media will be
used for collecting fish poop, uneaten food & other particles. Water will
flow through the coarse foam first, then it will pass through the medium &
fine foams. All big particles will be trapped by the coarse foam, & medium
& small particles will be collected by medium & fine foams.
Step 7: 2nd Basket of the Canister Filter:
Fine foam as well as aqua one premium
ceramic media will go into the 2nd basket.
Aqua one premium ceramic media is
a very porous media & many filters use this media. It offers the best environment
for the production of beneficial bacteria. Because it is very porous, large colonies
of beneficial bacteria will develop on the surface of the media.
Step 8: 3rd Basket of the Canister Filter:
Bio bakki balls as well as
ceramic rings will be added to the 3rd basket.
Beneficial bacteria will convert
toxic ammonia into less toxic forms. The end product of the nitrogen cycle is
nitrates, & they are not as toxic as ammonia. Bio bakki balls are used for
breaking down ammonia into nitrites & nitrates. It will consume ammonia
& nitrites but nitrates will be left.
Ceramic Noodles:
Ceramic noodles have lots of
small pores where air can’t enter. These holes will provide space for
denitrifying bacteria. This bacteria will consume nitrates. Denitrifying
bacteria grow in oxygen free areas. Ceramic noodles will allow both nitrifying &
denitrifying bacteria to grow on its surface. It will provide a large surface
for the growth of abundance of good bacteria. Large surface will allow lots of
good bacteria to grow on it.
Surface area is increased due to
many tiny pores.
Top Up:
On the top of ceramic rings &
bio bakki balls, Seachem Matrix is added.
Seachem Matrix offers the best biological
media for wiping out toxic chemicals. It provides both internal & external
surface for removing nitrogenous waste. The inside of the Seachem Matrix is
known as macropores for providing space for nitrifying & denitrifying
bacteria which is used for wiping out nitrates as well as ammonia & nitrites.
Step 9: 4th Basket of the Canister Filter:
I have added fine foam &
ceramic noodles in the 4th basket.
If water is still dirty then fine
foam will clean it even more & ceramic noodles will wipe out toxic chemicals
released from fish waste before clean water is sent back to the fish tank.
Top Up:
Fine foam & ceramic rings will be topped up by bio bakki balls. If there is still ammonia & nitrites present in the water then it will be wiped out by bio bakki balls.
Step 10: Close the Lid of the Canister Filter:
It is time to put the lid back on
the filter & screw it in place. Then fill the canister filter with water.
Now attach the canister to the
aquarium. Keep all connections in locked state till you complete the step of
attaching the filter.
Then it is time to unlock the
attachments & see if bubbles are releasing from the filter outtake &
intake pipes. Make sure you turn on the filter after all bubbles come out from
the pipe.
Step 11: Setting up Inlet & Outlet Pipes:
Connect the inlet hose to the
inlet bar. The end of the inlet bar is attached to a strainer which will allow
water to flow from the fish tank to the canister filter & will stop fish from
entering the valve.
Connect the outlet hose to the spray
bar to allow water to flow back to the fish tank. Spray bar allows water to
flow smoothly & provides a waterfall-like effect in your aquarium.
How to Clean an External Filter: Canister
- Make sure you clean the canister filter using your fish tank water. So, it is nice to clean the filter at the same time when you are changing partial water of the aquarium.
- Turn off the power & disconnect the plug of the canister filter. Close the tank connections before cleaning an external canister filter.
- Use a safe place where you can rinse the filter. Dirty water of the filter will flow outside of the filter so choose a safe place. Open all connections & allow the water to flow out of the filter.
- Open the lid of the canister filter. After removing the lid, you will see the filter baskets that are located just below the lid.
- It is time to take out the media baskets from the filter. You will find multiple media baskets that are connected together with the help of the rods. It is time to open the rod & remove the baskets from the filter.
- After taking out the baskets, the canister filter will be empty. Inside the filter, you will find some debris that needs to be cleaned. Use tank water to clean the inside of the canister filter. Wash it with water till all the debris particles are removed from the filter.
- Take out the foams from the inside of the canister filter. Place the empty baskets as well as the foams in the basin for cleaning.
- Clean the baskets & foams with aquarium water. As you rinse the canister filter with water, then all the blackness will fade away. Clean the media until all the murky water is washed away.
- After cleaning of the canister filter, then it is time to put back the media inside the filter. Put the baskets back in the filter. Place the things back in the same order as it was before you removed it.
- Time to close the lid. Now you can safely fill the filter with water.
- Connect filter to the fish tank. Turn off all connections before filter is attached to the fish tank.
- Then unlock all connections, & witness the bubbles that are releasing from the filter outlet & inlet pipes. Turn on the filter only when all bubbles are released from the pipe.
- Also, the tubes & pump require cleaning. But they don’t require frequent cleaning like the media of the canister filter.
