What Media To Use In A Canister Filter: A Guide For You!

Canister filters are one of the most popular types of aquarium filters out there, and it is understandable why. They have a lot of versatility when it comes to their operation, and offer a considerable amount of reliability when in use, both in terms of longevity and functionality. However, the versatility we mentioned comes in the form of the filter media that you can choose from. As such, we will talk about what filter media to use in your canister filter and give you tips on how to make it work!

When it comes to canister filters, there are three main types of filter media out there, and they are; Mechanical filter media, Chemical filter media and Biological filter media. Let us delve into each type of filter media and talk about what they are!

Mechanical Filter Media

Mechanical Filter Media

Mechanical filter media is the first stage of filtration in your canister filter, as the water then pushes into the other filtration systems after this. The mechanical filtration cleans out the large debris in your water so that it can move further into the canister filter for proper chemical and biological filtration.

In terms of longevity, mechanical filtration will last the longest in your canister filter, as long as you keep it clean and maintain it. Two common types of mechanical filters are pads and filter floss. Pads help control the flow of water moving through the canister filter, and also easily catch the debris flowing through due to its porous texture. Filter floss is made up of wool and also serves the same purpose by catching the debris in the water. 

Maintenance of the mechanical filter is highly recommended as this segment influences the performance of the rest of your filter.

Chemical Filter Media

Chemical Filter Media

Chemical filtration of your aquarium water involves its detoxing. This means that the chemical filter media will remove odors from the water in order to make sure that it is breathable and non-toxic for your fish and aquatic plants to live in.

Carbon pads are the most common and easily accessible chemical filtration systems out there. You can also look into poly-filters for this system, which turn the water into a darker colour to warn you that they have worn out.

In case your water has phosphates in it, you can easily chuck in some Granular Ferric Oxide filters to clear them out. Not only that, but you can also deter algae growth in your tank with the help of these oxide filters. The only way to test if this filter has depleted the level of phosphates in your water is by testing separately for the phosphates in the water.

Chemical filter media has the tendency to remove helpful nutrients from your water, for which you will need to do some meticulous research into what works best for your aquarium.

Biological Filter Media

Biological Filter Media

In natural environments you will find that there are various different organisms living in order to create the perfect atmosphere for aquatic life. This is where the biological filter media comes into play.

Biological filter media has a lot of versatility when you think of it. You can choose from a diverse selection, all of which provide the area for the beneficial bacteria to grow in. These include bio balls, ceramic rings, string media, etc.

Bio balls and ceramic rings both are great for being placed in at an abundant amount, and for providing a high surface area for the beneficial bacteria to grow and thrive in. String media does the same job, and can also aid in mechanical filtration when the time comes. Bio filter requires special care and needs to be maintained properly in order to work properly and for the time that it should. Otherwise, you may end up killing the bacteria and making them useless.

Factors To Consider When Choosing Filtration Media

Choosing the type of filter media can afford you a lot of versatility, but there isn’t much to choose from when you really dive into it. The biggest thing to keep in mind is how big your aquarium is. If you have a large tank for your aquarium, then you could look into getting porous media, so that it provides an easy passage for the water in the tank.

Saltwater aquariums are also rising in popularity these days, so if you want to engage with a reef aquarium, then you might want to steer away from carbon pads, as their nutrient removal might affect the aquarium negatively.

You will also need to look into low maintenance filtration media if you are someone who does not have too much time to look into your aquarium. Since filtration media will affect your tank directly and all the organisms will need to be considered as such.

While the filter media is important, you will also need to take care of the canister filter as a whole, for which canister filter maintenance takes priority. Thus, you need to make sure you are fully clued up on how to do these tasks.

The Takeaway

Canister filters are an easy choice to make when you want to look into your very own aquarium, and for good reason. However, you need to make sure you have all the information before you make the ultimate choice. While they operate very well, canister filters require some form of understating about aquariums and research as well. Once you have decided on the size of your tank and whether you want a freshwater or saltwater aquarium, you can then decide on the different types of filter media you want in your canister filter. Hopefully, we have provided you with all the necessary information, and you can go on to make the best choice possible!
