How to choose a canister filter for an aquarium?

  • Purpose of the canister

While choosing a canister filter, it is essential to ask yourself some vital questions. How many gallons of water are you interested in getting cleaned? Is the canister that you are choosing capable of handling the water flow and other factors? All of these things come in handy when you are picking up a cartridge and will help you make a wise decision in the end.

  • Adaptability and durability

Another critical factor to consider is where exactly do you plan on placing the canister. This is viewed as necessary because it will determine whether or not a specific type of cartridge be suitable for your said aquarium. If a brand of canister suits your plan, go for it. If it does not seem right, reconsider your choice.

On the other hand, the durability of the canister is also to be held into account. You need to ask yourself what type of investment you are looking for and can you afford to change your canister frequently. You need to make sure that the canister you choose is durable and will help you out for a long time.

  • The Motor

A motor in a canister helps to pump in water from the aquarium into the filter to enable it to get filtered. Hence, the engine is a significant part of the canister. You need to make sure that the motor you select is not only efficient but also low maintenance. Different motors have different needs for support, and it is essential to consider this factor before picking up a canister filter.

  • Tank size

Keeping the size of your tank in mind before making a purchase is essential. This is because not all filters can accommodate all types of containers. You will find the size of tank a filter favors written on it. You can also find it out by contacting the company that made the canister filter. Some filters prefer 10 gallons, some 20 gallons, and some even more. Owning a larger tank and getting a filter designed for smaller aquariums can lead you to issues. The filtration unit won’t be able to do its job correctly. This would mean polluted tank water, leading to stressful living conditions for your fish.

  • Brands

The brand of the canister plays a massive role in the functioning of it. A good brand comes with many great reviews and an assurance that your money will not be wasted in any way possible. No matter how big or small your aquarium or tank is, you need a good filter for it. To have it, you need to do your research and look at the reviews that people leave behind. Very often, relying on just what the manufacturer says is not good enough.

  • Your budget

Your budget is what decides for you at the end of the day. However, you should not hurry into buying any canister filter that is the cheapest one. Having thorough research is essential and will help you land a reasonably decent canister. You will also find that there is an extensive range of canister prices that you can pick from. You can always start looking online first and get a good idea as to what you are dealing with.

How does a canister filter work?

While reviewing your options, you will discover that there are many different ways in which a canister filter works, and you need to know them before making any big decisions. Some of these filters have a UV sterilizer, while others have canister filter media.

Canister filters are attached to tank exteriors and have one piece inside their aquarium.  They have inlet and outlet fittings, which enables water to move in and out of them quickly. Some cleaners have an in-tank pump, while some have mounted motors that rely on gravity to start the engine.

When a filter starts functioning, water passes through various filtration layers that are present inside the canister. There are many layers of membranes present in it that trap harmful microorganisms and debris present in the water and make it clean. They also make sure that only the freshwater is let out of the filter and reintroduced to the aquarium.

Since the canister filters require maintenance now and then, you must learn how to do that as well.

Advantages of using a canister filter

  • Easy setup processes
    Unlike the other filters, the canister filters are relatively easier to set up. This claim is attested by several clients who chose the canister filters. All you need to keep in mind is that the instructions provided along with the filters are quite detailed and need to be followed word to word. By doing this, the risks of wrongly setting up the filter will be reduced.
  • Easy to clean
    Everything that you need to know about cleaning the filter is already present in the manual. Having a thorough look at the manual will help you save time and work more efficiently and confidently. In addition to this, the components of the filters are easily disassembled. This means that you can get access to the internal regions without any difficulty. After you get everything cleaned up, you can place it back and enjoy the crystal clean tank once again.
  • Quiet operation
    Having a filter that does not produce noise is a blessing. It is crucial to have an unnoisy filter as it allows you to carry out your daily tasks without any disturbances. The canister filters are probably the only filters that promise a quiet operation. This fact has been approved by many users who have left behind positive reviews regarding this filter.

Conclusion

It does not matter if you are new to keeping fish or want a change for your fish; having the best canister filter for your aquarium is important. Penn Plax Cascade Canister Aquarium Filter is the one which I mostly recommended to client and really I love its durability and reliability. It will decide whether or not your fish have a good living experience. Ensuring that your fish have a healthy environment to thrive in is incredibly significant as it affects the growth and reproduction capacities of your fish. A fish will only reproduce if it is kept in an environment that favors the growth of its infant. Therefore, if you want to have a continuous marine life in your aquarium while making sure that the aquarium is a treat to watch, you need to make sure that it is clean at all times. No one likes being close to a fish that is aesthetically unappealing and reeks of horrid smells. In addition to this, having dirt in water also clouds the vision of the fish present in the tank. This means they have difficulty finding their way about and looking for food. Taking your time out and finding the perfect canister filter will make sure that neither you nor your fish have to suffer at all.

How to Clean Canister Filters?

Regularly cleaning your aquarium filters is important for the health of your fish. While it may seem like an intimidating job, it really isn’t. There are three kinds of filters, mechanical, chemical and biological. Depending on what kind you have in your tank, you will have different processes to carry out. 

  • Mechanical Filter

In case you are working with mechanical filters, you will find that there is a sponge sitting at the inside it. Following are some basic steps to help you through the process:

  • Scoop out some tank water

While you could go with tap water to clean your filter, it is advisable that you use existing tank water to ensure that your fish is less sensitive to the change. Siphon out two-three cups of water into a bowl.

  • Unplug the filter

This is important to avoid getting electrocuted during the cleaning process.

  • Clean the sponge

Dip the sponge into the bowl with tank water. Rub and squeeze it thoroughly to ensure that all the gunk within it is removed entirely. Since this does not harm the good bacteria in the sponge, feel free to wash the sponge in as much detail as you want.

  • Clean the tubing and casing

You can use the tank water in the bowl to clean the other parts of the filter or can get more water from the tank.

  • Reassemble the filter

With the last step done, your filter is ready to be reassembled. Carefully, put everything back together and turn the filter on.

  • Chemical Filters

Chemical filters require the changing of carbon in them on a regular basis. If you feel that the tank water is becoming cloudy, repeat steps 1,2, and 4 from above, after you have replaced preexisting carbon.

  • Biological Filters

To clean a biological filter, repeat steps 1, 2, and 4 from above, in addition to cleaning the filter using tank water. Do not do it very thoroughly as you might end up damaging the microorganisms in the filter.

How to Set up a Canister Filter for Aquarium?

Canister filters are excellent filters to keep an aquarium squeaky clean. If you have gotten one and are wondering how to install it in your tank, read the guide below.

  • See if you have all parts

The first thing you need to ensure before starting the setting up procedure is that you have all necessary. Make sure that all of the parts are present (by checking them against filter’s part listing) and are not damaged.

  • Set-up your tank

The way you position your tank impacts how your filter is ultimately positioned, which impacts its functioning. The filter should rest below the tank. How far below it must be can be determined by consulting the user guide that comes with the filter. Position your tank accordingly and then fill it water.

  • Prepare your filter

Remove the filter’s head and verify if all media baskets are present inside and intact. Next, carefully add your desired media in the baskets, layer by layer. Remember the following order:

  1. The mechanical media must be added in the first tray. Order your sponges from the least fine to the finest, to make sure that all debris is removed before it gets to biological and chemical media.
  2. The next tray should be loaded with biological media. There is a wide range of available biological media in the market, including ceramic rings and bio-balls. Choose the one that suits your ideals.
  3. The third and fourth trays allow experimentation. You can mix things up and experiment with a few things. However, it is advisable that you dedicate one tray for some chemical medium, like charcoal.
  • Set-up intake and output channels

To prepare the intake channel, attach one end of the hose to the filter and lower the other end into the water tank. Typically, filter manuals suggest the length till which you must lower the pipe in water. If it is absent, you can go with the rule of thumb, which is to keep the hose 3 inches above the tank bottom. The output channel is set similarly.

  • Turn on the tank

Lastly, make sure that all connections are proper and all valves are open. Once satisfied, plug in your filter and turn it on. 

How to change the aquarium filter without losing bacteria

Very often, the owners of an aquarium have to change its filter. A common fear in the minds of these users is the loss of useful bacteria. However, there is a way this problem can be avoided. One thing that you have to keep in mind is to not remove all the filter media at once. Many new fishkeepers try to get done with the process at once, resulting in the loss of bacteria. In case you do this, you should stop feeding the fish for a few days. This will help lower the ammonia content of the aquarium. Check if the ammonia is still present in the water. If it is, then remove 50 per cent of water change. Then, add some live bacteria that will compensate for the lost bacteria. You need to check the water daily to ensure that no ammonia or nitrate is present in the water.

On the other hand, if you have to buy a new filter as a replacement, you should add the entire filter media of your previous one to the new one. Even if it does not fit properly, the water flow will be efficient. All your useful bacteria will be saved.
