What Is Bio Media And How Biological Filter Media Works In Canister Filter?

By bio media or biological filter media, we mean something inert that works to create, nurture and sustain housing for useful bacteria that help to break down the solids to purify them from toxic elements.

This media can be used with either mechanical or chemical media to strengthen its action. You should not replace this media if it is not too clogged to do its work as it should be.

To get a clear understanding of this media, it is important to know the prerequisites that the bacteria need to use to create and preserve the favorable conditions to grow:

  • The temperature of the environment should be above 55°F.
  • As a food source, it requires either Ammonia or nitrite.
  • It requires an ample supply of Oxygen.

Bacteria collect their food and oxygen from the water. But, if the bio media is blocked by particulate matter, the water flow decreases and the bacteria die as a result. So, it is important to make sure that you have installed mechanical media before placing bio media.

Conversely, the abundance of ammonia and nitrite reproduce the bacteria if the bioload increases. However, it is required to have harmony in the water so that the bacteria do not cause a “bacteria bloom” by over-production or does not get destroyed completely.

For established tanks, bacteria bloom is too common to happen and gets resolved quickly by itself in 24 hours. But when it comes to the new tanks, the conversion of ammonia by bacteria may take a longer period depending on the starting level of bacteria and current fish load. Bio media works as the breeding ground for the bacteria to thrive and get involved in the nitrogen cycle.

Bacteria And Biological Filtration

Our aquarium is flooded with hundreds of micro-organisms that we do not see. They exist to break down organic substances. They also help to recycle nutrients.

By the way, when it comes to bio or biological filtration we want the removal of both the ammonia and nitrite which are toxic.

Three types of bacteria perform certain tasks to purify the water.

  • The first type of bacteria transforms the ammonia to nitrite.
  • The second type of bacteria transforms the nitrite to nitrate (relatively less harmful). The bacteria that do this work are usually labeled as “nitrifying” bacteria.
  • And there is the third type of bacteria that convert the nitrate into nitrogen gas by a process which is known as the denitrification process. This process helps to keep the corals alive.

The Truth About Bacteria And Biological Filtration

There are many myths concerning bacteria and biological filtration. However, the nitrification process and the concerned bacteria in the aquarium are well-revealed in the latest researches. Here, we will have a look at some of the views and myths and check whether those are valid or not.

Common view:

Nitrifying bacteria die in a lack of high oxygen supply.

  • Reality: This is False. Nitrifying bacteria can survive even in low oxygen supply.

Common View:

The biological filtration needs a high level of aeration and oxygen to enable the bacteria to work properly.

  • Reality: Just normal water movement is enough to ensure proper oxygen and appropriate aeration. It is not required to go for more aeration.

Common View:

Bacteria in saltwater are way different than freshwater tanks.

  • Reality: This statement is mostly valid. We see some species of nitrifying bacteria present either in freshwater or saltwater. However, the exception is also noted. Some bacteria are found in both types of water.

Why Do I Need Special Biological Filter Media? 

Many issues can disturb the harmony of bacteria in the aquarium. Glass scraping, washing plastic plants, cleaning of gravel, changing of water, etc. can minimize the effect of bacteria in the biological filtration system. No matter what happens in the rest of the places of the aquarium, the bacteria need a stable and safe environment to grow. This is the main task of best biological filter media to help the bacteria do their work. The colonies of bacteria supply constant nitrifying bacteria which are very important to keep the process going on. You need special and best biological filter media for turtle tank due to several reasons such as:

  • To maintain low ammonia and nitrite level in big tanks
  • Some fishes release more ammonia, an extra biological media helps to keep the biological filter stable.
  • Reef aquariums need biological filtration for denitrification.
  • Natural planted aquariums do not need many biological filter media.

What Biofilter Media Order Should I Maintain In My Filter? 

In most of the biofilter process, water passes through a bed or chamber of media. All the suspended organic materials, leftover fish food or fish waste gets settled in the biofilter media.

When it comes to the heavier particles, these will settle either in or on top of the biofilter media. If you set your canister filter in a way that lets the water flow through the bio media first, you can find sludge and debris stuck in it as it will start working as a mechanical filter automatically.

However, it is to be noted that most of the accumulated organics can produce non-nitrifying bacteria. If it occurs, the nitrifying bacteria will soon be crowded out by the non-nitrifying ones.

That’s the very reason, it is important to set the biofilter media in the cleanest part of the filter system. Using prefilter media to remove solids can come to your help.

What Should Be The Proper Amount Of Biofilter Media?

You may not find instruction from every manufacturer about how much to use per gallon. One reason is that one biofilter is usually designed and packaged for a specific filter.

And to be frank, there exists no hard and fast scientific formula to calculate the biofiltration media.

There is a difference in every aquarium as there is variety in fish, invertebrate size, number and food amount.

The nitrate reduction case is also the same. If your manufacturer suggests you to go for a certain use rate, you should follow that. You can add more media later on if you need it.

Benefits Of Biological Media

There are many benefits that a biological media offers. I am going to tell you specifically about two popular benefits you can get from it.

The first advantage that you get if you use the biological filter media is the cleaner and fresher water. It is due to the process by which this result is achieved. But, how does it takes place? Let’s dig into the deep.

Tanks can be cleaned and filtered with traditional ways. But, there are ammonia, nitrite,  and nitrate that gets accumulated in the water and make it toxic. It is nothing other than a biological media that works the best to remove all the above-mentioned harmful materials from the water. Do you know how? Well, it is through the bacteria colonies from where the water gets an unending supply of bacteria to clean the water from toxic substances quite easily.

The second reason or advantage that a biological filter media offers is simplicity. You will find it easy to use. Most of the time, you can directly place them inside the mechanical filter. So, there is no hassle in the installation. If you have a filter already bought for your aquarium, just take your bio media filter and place that inside the existing filter and you are done.

How To Setup Biological Filter Media In The Filter? 

Well, let’s get to know about how to set up the bio media in the filter. It is easier to do it if you know the way. At first, you need to choose a good filter media (refer to the products we have reviewed). After getting your media, open the filter and place the filter in the right place where it should be. This may vary from filter to filter. There are back filters, canister filters, underwater filters and so on.

However, if you do not find the right place to set up your media in the filter, you should read the user manual. And if you do not have a user manual right away or you have lost that, take help from the internet. Just search your filter type (and manufacturer name also) and you are sure to get your desired information. [But, if you own a canister filter, you can read “How to set us a canister filter like a pro“, I am sure, it will help you more].

However, one thing you should never ignore, and that is choosing the best biological filter media that works.

Final Words

Now that you know everything about the bio media filtration process and best bio media for canister filters along with the buying guide, it will be easier for you to buy the right one. Just keep in mind to choose the durable one that offers good quality and does its work properly.

We hope that the reviews of the products with their pros and cons and our buying guide with necessary information would be of your help.

    I want distribution of Vietnam

    1. Hi Reo, I don’t know about distribution to Vietnam! I am also not a distributor. I am sorry as I am unable to help you with this issue.

  2. Bella Smith

    This is really an amazing value. Ceramic filter media like anything else in life vary in quality a great deal. Fluval Biomax is incredibly porous because it’s not tumbled and polished. It’s the rough texture and millions of tiny crevices that attract nitrifying bacteria like a magnet and encourage rapid growth.

    1. hi Bella, yes your knowledge is pretty clear on it. Thank you for sharing your knowledge with us.

  3. PapaP

    Mud has always been, and will always be, the best bio-media on earth. Can you dig it?

    1. Hi Papap,
      First of all, I would like to thank you for reading this article!
      Yes, I agreed with you. Mud/ soil is the best bio-media. But you can not use Mud directly to your aquarium you know. You are correct, Bioretention soil is added to remove dissolved pollutants. The Mud mix used for bioretention systems is central to determining flow control and water quality treatment.
      For Mud media, you can use Mineral Mud Filter Media for Aquarium, and if you like, you can try EcoSystem Aquarium Miracle Mud.
      Soil is one of the most important elements of an ecosystem, and it contains both biotic and abiotic factors. If you are interested, you can read about Soil Composition.

      Off-Topic: I just published a new article on betta fish filter requirement. If you are interested to know on betta fish, you are invited to read my article..

      Thanks again! stay safe and take care of your aquarium fish.

  4. Mark

    I have Biohome Ultimate in my filter and it never reduces nitrate down to 0ppm. The suggestion it does is bogus.

    1. hi Mark, thanks for letting us know the fact! Honestly, there are NO media that will reduce/remove nitrates in an aquarium on this earth. The only way to reduce nitrates is with water changes and plants. But on the other hand, if we need to recommend, then I can guide you to follow below steps-
      Step-1: Water change!
      Step-2: Use Water conditioner, best is Seachem Prime Fresh and Saltwater Conditioner – Chemical Remover and Detoxifier.
      Step-3: Use Ceramic rings also help.
