Best Aquarium Filters – To Purify The Water In 2024

Filtration is one of the key components of an aquarium or fish tank. As important as it is, you should never cheap out on the filtration of the aquarium as it is responsible for moving and cleaning the water in the fish tank.
A filter is a component that retains the purity of the water, ensuring that the water stays clean while allowing for the water to remain safe for the fish.
While there are many filters in an aquarium, you need to know which one is which and how a specific type of filter may serve its purpose for various types of aquariums.

What are the Different Types of Aquarium Filters?

As mentioned at the beginning, filtration is one of the key aspects of an aquarium or fish tank. There are different types of aquarium filters, categorized into three main types that include:

  • Mechanical Filter
    A mechanical filter or mechanical filtration in an aquarium deploys the use of sponges, filter floss pads, and filter socks. What these sponges, socks, and floss pads do, is that it physically strains out debris from the water in the fish tank, similar to what a coffee machine does with coffee. In essence, a mechanical filter acts as a trash can that houses all the impurities, dirt, and debris. A mechanical filter is ideal for keeping your water clean, especially when you have a large fish tank with more fish inside.
  • Chemical Filter
    Coming towards the chemical filter or chemical filtration process, this type of filtration component uses special chemicals like resin or activated carbon to remove chemical-based impurities from the water, including medication and tannins. Once the entire area of the chemical filter is covered, you will need to replace the filter again to continue to block impurities. A chemical filter, therefore, is ideal in situations where you want to clean all kinds of impurities from your fish tank.
  • Biological Filter
    A biological filter or biological filtration process entails certain aquarium plants or beneficial bacteria to filter out the water. Such plants or beneficial bacteria absorb nitrogen compounds and toxic ammonia that are generated and released from the feces of your fish. The beneficial bacteria reside in the fish tank and grows on any kind of surface including the aquarium gravel and walls of your fish tank, which is why biological filters are equipped with bio-rings or bio media that allow for the bacteria to live in more places as its surface area is large. Hence, if you were looking to make your fish tank the safest, then a biological filter is the way to go.

Are Filters Really That Necessary For Aquariums?

After going through the types of aquarium filters, you must have a general understanding of the significance of filters in a fish tank.

Well, the golden question is not the types of filters, but rather, do you really need a filter for your fish aquarium?

The answer is ABSOLUTELY YES.

At the very least, all of your fish tanks must have an equipped biological filter as they are the cheapest. An aquarium filter not only helps in keeping the water safe from impurities but also allows a safe habitat for the fish, ensuring a sustainable ecosystem for the aquatic life inside the tank.

Without a filter, your fish will die from the growing bacteria inside the fish tank.
