So, why should you use this device on your aquarium?

Can hold more filter media

With a capacity of 50-55 gallon fish tank, the canister filter must be large enough. This means it should hold more filter media compared to those with smaller capacities.

Another important point to note down is that more filter media means faster growth of beneficial bacteria in the tank. These bacteria play a very significant role in the filtration process.

Once established in the media, they will most likely help remove harmful substances, especially such as ammonia, nitrites and nitrates, during the process of filtration.

So, more filter media makes filtration efficient and effective compared to less media.

Can go for much longer

Time is of the essence when it comes to fish tank filtration. The longer it takes to filter the tank water, the better the quality of water for your fish. It’s critical to ensure that your choice of a filter has the best flow rate and can last longer for proper filtration.

A strong flow rate is critical to proper and timely filtration. This will allow tank water to flow faster through the media in order to maintain a  healthy environment in the aquarium.

Normally, a good filter is required to filter at least 4 times the total volume of the aquarium per hour.

It is always  wise to choose a bigger filter to ensure optimal water filtration. A large filter holds more media through which the dirt from the fish tank can disperse, letting water to flow smoothly. With more dirt being trapped, there will be efficient filtration of water.

An oversize filter holds more filter media in the canister. The filter media is what purifies water during the filtration process.
