What are the Aquarium Bio Balls?

Aquarium bio-balls are used as highly powerful biological filtration for the aquariums. 

How do Bio Balls work?

Bio Balls helps in the production of good bacteria by providing them with enough surfaces to grow. The nitrifying bacteria improve the quality of water by filtering the water.

Aquarium bio balls act as the best biofilter in sump or external filter. 

How to use Aquarium Bio Walls?

Bio balls are mostly submerged underwater in sump or HOB filters. However, in trickle-filter setup, you cannot place bio balls underwater.

The only time you wouldn’t place bio balls underwater is if you are using them in a trickle-filter setup. Plus, it is recommended to use a filter floss or sponge before directly using bio balls. 

What is the difference between bio balls and ceramic rings?

There are two main types of bacteria, nitrifying bacteria and denitrifying bacteria. Bio balls can carry on nitrifying bacteria but ceramic rings can carry both nitrifying and denitrifying bacteria. 

The main advantage of bio balls over ceramic balls is that they last forever. On the other hand, you need to change ceramic balls over time.

How many bio balls per gallon freshwater?

Bio balls are available in a range of sizes to fit different types of filters. You will be able to fit smaller bio balls in the same-sized filter than you will large ones.

If you have an aquarium of 100 gallons then you need to use 2.2 gallons of bio balls. You can easily fit more bio balls in a filter as they come in both large and small sizes.

Conclusion

Bio balls are great for developing good bacteria in your aquarium. Your aquarium will surely get the best biological filtration. However, ceramic rings work great for building bacteria that remove nitrate.
