5 Ways To Have Effective Filtration In Your Aquarium

1.Oxygen Levels


Beneficial bacteria need oxygen to break down (oxygenate) waste. Maintain high oxygen levels in the tank through sufficient gaseous exchange mechanisms. This is done by usage of surface skimmers and flow patterns that exchange surface layer of water with deeper layers in the tank.

It is also worth mentioning that the larger the surface area of the water, the more efficient the gas exchange.


2.Proper Substrate

Soil Bio-filtration mainly depends on

1.Soil components and chemistry

2.Pore Size

3.Particle Size

Increased porosity allows better beneficial bacteria colonization.


3.Filter Media Selection

Bio filter media are intended to provide a safe and stable environment for the bacteria, no matter what happens in the rest of the aquarium. The bacteria colonies living in and on the bio-filter media act as a nitrifying bacteria farm, releasing a steady supply of new beneficial bacteria to recolonize the entire aquarium.

4.Aquatic Plants


Plants are also excellent filters in an aquarium. Few plants can absorb the fish waste products, excess food, and decaying substances. These plants also encourage the proliferation of “good” bacteria for biological filtration.

Yes it’s possible to just use only plants as a bio-filters, but plants and filters together can provide superior results.


5.Water Parameters

Maintaining stable water parameters is key. This also means avoiding spikes of toxic elements. Before you actually decide to go make any changes, realize that the fish may be just as happy as they are now and attempting the change the parameters is difficult and could potentially end in disaster. Think twice before attempting to adjust the water parameters in the aquarium.

Conclusion – How Bio filtration works?

Bio filtration is process of conversion of  harmful chemicals into useful chemicals using beneficial bacteria.Does this sound’s confusing? Don’t worry it’s a simple process

Think about the nitrogen cycle for a moment. Waste, such as fish poop or uneaten food, breaks down and releases ammonia. Bacteria then eat the ammonia and convert it to nitrite. And then, another type of bacteria converts nitrite to nitrate. This is biological filtration at work.

But if you ask me for best aquarium filter, I probably lean towards canister filter, as it offers biological, chemical, and mechanical filtration.
