Pros and Cons of Marineland Bio-Filter Balls (Benefits):

Bio media is extremely important for aquarium filters as lack of biological filtration is the reason why most of the fish die in fish tanks. For biological filtration, bio media is required that offers a surface where beneficial bacteria grow in abundance. Toxins released from organic waste do not react with the bio media but when they interact with the beneficial bacteria, they are broken down into less harmful compounds. Fish poop & other debris release ammonia, which when react with the good bacteria, are broken down into nitrites & nitrates. Ammonia is more toxic than nitrite, & nitrite is more toxic than nitrate. Fish can live with nitrates in the water.

If you want to try bio balls, then a question may arise in your mind, 'Can Marineland bio balls remove nitrates from the aquarium water?'. In this post, we have provided an answer to this question, as well as other questions so please read until the end.

Benefits of Marineland Bio-Filter Balls:

An important benefit of using Marineland bio-filter balls is they efficiently wipe out ammonia & nitrites from the water leaving behind nitrates. For removing nitrates, it is important to change partial water on a weekly basis or use specific bio media, which house anaerobic bacteria for removal of nitrates.

Using Marineland bio-filter balls, your fish tank will be clean as these balls remove ammonia & nitrites. These balls are multi-faceted, unlike solid balls; therefore, they offer more surface area for the growth of nitrifying bacteria. More bacteria can cling to the multi-faceted structure, thus speeding up ammonia removing capabilities, & making these balls compatible for a heavy stocked aquarium. Marineland bio-filter balls are one of the top bio media for planted aquariums.

Marineland Bio-filter balls are compatible for a wide range of aquarium filters. The manufacturer suggests using Bio-filter balls for Marineland canister filters, but they can be used for other filters too.

In addition, while most of the other bio media require replacement after a certain period, this is not a problem with Marineland bio balls. Since bio balls are manufactured with plastic, they can be used for a lifetime. If your Marineland bio-filter balls are dirty, just give them a good wash.


Pros and Cons of Marineland Bio-Filter Balls:

We have already discussed some pros of using Marineland Bio-Filter Balls that are summarised below:


Pros of Marineland Bio-Filter Balls:

  • Help multiply good bacteria to efficiently wipe out ammonia & nitrites
  • More surface area is available due to the multi-faceted surface of ball
  • Available at low cost
  • No need to replace bio balls
  • Unlike other bio media, overtime they do not lose their efficiency
  • Easy to rinse bio balls when they are dirty


Cons of Marineland Bio-Filter Balls:

  • Do not remove nitrates from the water

For removing nitrates from the water, either add live plants that will consume all the toxins including nitrates or change partial water every week.


Why should I use Marineland bio-filter balls?

Marineland bio-filter balls are multi-faceted plastic biological balls that make them more efficient than classic solid balls, which means that they have more surface area for the colonization of good bacteria & offer more contact time with toxic water.

As Marineland bio-filter balls are developed from plastic, they do not require replacement & they can work for a lifetime. Bio balls are affordable & extremely efficient for removing toxins excluding nitrates.



Marineland Bio-filter balls are everlasting, & very efficient in removing ammonia & nitrites. However, the only drawback of bio balls is that they can’t remove nitrates.
