What does Filter Media mean? (Easy Guide)

Filter Media

Choosing the right Filter Media is important in the aquarium hobby, but what does filter media mean? Understanding why and how it works should be the main focus. This very easy to follow guide will help in choosing the right media that fits your set up best.

 



 

Why do we need media in our filters?

The media in our filters is what actually cleans the water by removing waste product and toxic elements before returning it to your tank. Media also adds surface area for beneficial bacteria to grow on which is needed to complete the nitrogen cycle.

The nitrogen cycle in an aquarium is very important for the livelihood of everything in your tank, including fish, plants, and coral. Understanding this cycle will put you far ahead of the learning curve in your fish keeping journey. Watch this video for an informative, but simple explanation on the Nitrogen Cycle.

 

Order of Media

There are 3 primary stages of filtration that happen in your canister filter. They are Mechanical, Biological and finally Chemical, in that order. No matter what type of filtration you use, be it a canister, hang on back (HOB), Sump pump…etc. The order of filtration never changes.

 

 

Mechanical Filtration

When water enters your filter it must be mechanically filtered first. Mechanical Media consists of sponges and pads ranging from very course to very fine and everything in between. Water should hit the most course sponge first and work its way to the finest sponge before entering the next phase of filtration.

What this accomplishes is grabbing and trapping all the particles in your water. These particles consist of fish waste, excess uneaten food, decomposing matter, and basically anything floating around your tank that shouldn’t be there.

This stage of filtration is what produces that crystal clear water look we all want in our fish tank. If you’re having problems achieving this check this article out on Crystal Clear Aquarium Water.



 

Biological Filtration

Once your water has been cleaned and filtered of any detritus it enters the next stage of filtration, biological. Biological filtration is where your beneficial bacteria will grow and multiply. This is accomplished by adding surface area to your filter. There are many products that do a great job at providing this biological filtration.

 

Types of Biological Media

There are many products available that claim to be the best bio-media around. Listed are a few of the top brands (In no particular order) with their descriptions directly from the manufacturer. Keeping in mind that all of these work extremely well.

 

 

Seachem Matrix

Seachem Matrix

 

Matrix is a highly porous media designed to provide exceptionally efficient bio filtration for single site removal of ammonia, nitrite, and nitrate from freshwater, marine, and reef aquaria.

Each liter of matrix provides over 160,000 cm2 (170 sq. Ft.) of surface, equivalent to over 40 L (10 gallons) of typical plastic ball media.

 

 

 

 

Fluval BioMax

Fluval Biomax

 

Fluval BIOMAX bio rings have a complex pore system creating an optimal environment where beneficial bacteria can thrive.

BIOMAX bio rings have more capacity than most biological filter media and allow ideal water movement throughout the media to ensure optimal contact time for efficient biological filtration for freshwater and marine environments.

 

 

 

 

Bio-Home Ultimate

Being capable of supporting the aerobic and anaerobic bacteria, it ensures that natural processing of ammonia, nitrite, and nitrate can be achieved.

 

 

 



 

Chemical Filtration

What does filter media mean

 

The final stage of filtration is intended to reduce organic compounds, odors, toxins, medications and dissolved metals in your water. Chemical filtration is not a necessary component and is usually added based on preference.

It can also help to amplify the clarity of your water but keep in mind that chemical filtration gets “used up” and must be replaced once consumed or it it can release all the additives right back into your water.

 

 

 

 

Types of Chemical Media

There are many products available that claim to be the best chemical media around. Listed are a few of the top brands (In no particular order) with their descriptions directly from the manufacturer. Keeping in mind that chemical filtration is not necessary or required in your aquarium but can be used for specific applications. All of these listed work as advertised.

 

Marineland Activated Carbon

Conclusion

So what does filter media mean? It means the choice you make in filter media will effect the quality and cleanliness of your tank water as well as the overall health of your tank mates. Understanding how all this media works together will help you make a much more informed decision.

So keep your sponges clean, make sure you have enough bio-media for bacteria growth and the choice is yours if you’d like an extra boost by choosing a chemical media. Don’t forget to enjoy the journey!
