Don’t you like a clean and fresh home? Your fish might think the same. If you are planning on bringing home a fish tank or even thinking of it, the first and foremost duty of a fish parent is to keep the glass world of your fish clean and fresh to keep them healthy, happy, and lively.
There are a few aspects you need to consider before buying a filtration system for your aquarium. All filters may not be appropriate for every tank. The size of your fish tank, the types of fish, and the requirements of your fish play important roles when it comes to an aquarium filter.
Choosing the appropriate filter from various products might be difficult if you are new to the fish world. Well, don’t be confused, now that we are here. Read the article below to clear all your confusion regarding the filtration systems for your aquarium.
Why is it important to choose the right filter for your aquarium?
In simple words, your aquarium is an artificial miniature model of the underwater ecosystem. Due to the compactness (lots of plants and fish) inside, your tank water may get polluted quickly. In the natural habitat, the water is cleaned, balanced, and cycled naturally. But when it comes to the aquarium, providing a natural environment and comfort is solely your duty.
Since the aquarium is not a self-cleaning device, it demands an external cleaning method. A subtle change in your tank water due to dirt and filth may cause the death of your precious pets. Filters are the external cleaners of the tank water.
They clean, refresh and balance the water that is required to maintain your aquatic pets. Installation of an aquarium filter can reduce your headache of taking care of pets, although that should not be your excuse for not cleaning the tank yourself!

Types of filters:
There are a variety of filters available in the market depending upon the three types of filtration (mechanical, chemical, and biological). Filters that include the three types altogether are the best ones. The most popular filter types include canister, hang-on-back (HOB), sponge filters, and under gravel filters.
Canister filters are the most suitable choice for larger aquariums of more than 40 gallons. You might find them for the smaller tanks as well. This type of filter provides the best cleaning process, amalgamating the mechanical, chemical, and biological filtration. The water goes through fine material to filter the smaller particles. It is a wonderful choice for aquariums with koi and cichlids as well as plant and saltwater aquariums. However, they can be a little expensive to afford.

The-hang-on back filters are the most popular ones among aqua hobbyists because of their simplicity and ease. The HOB filters likewise work effectively in cleaning your fish tank. They draw water from your tank. After the three types of filtration, the pure water goes into the tank again. You can easily maintain these filters without putting your hands inside. The only problem is that the good bacteria colony is also lost every time you wash it.
These pocket-friendly filters are the most basic ones. They don’t do chemical, biological, or mechanical filtration. They are run by an air pump that cleans the water with a sponge material. These types of filters are applied in hospital tanks or tanks with smaller fish.
Under gravel filters:
These filters are set under the substrate of the aquarium. They clean the water by applying mechanical and sometimes biological filtration. Chemical filtration does not happen here.

How to purchase the right filter:
Buying a suitable filter for your aquarium involves considering some essential factors. It would be best if you put a little bit of thought before you grab a filter for your aquarium. Choosing the appropriate filter can make your pets love you more.
1. Filtration type:
There are three types of filtration, namely mechanical filtration, chemical filtration, and biofiltration.
Filters that amalgamate three of them are thought to be the best ones.
2. Aquarium size and flow rate:
Another crucial factor to note is your aquarium’s size. It plays a vital role in choosing a filter. All the water in your tank should be filtered four times per hour. For example, if you have an aquarium of 50 gallons, your filter’s flow rate should be 200 Gph (Gallons per hour). Seems pretty easy to calculate, isn’t it?
Also, the larger your tank is, the better your filter should be. The external filters can be the ideal choice because they are generally bigger.
3. The purpose of your tank:
The purpose of your fish tank is an important aspect to look at. For example, tanks that are used for medicating fish or for breeding purposes usually require sponge filters.
You should also note the types of your fish. Some fish and plants need powerful filtration, for they produce an excessive amount of wastes.
Five general FAQs you might look into:
- Should I rinse my aquarium filter?
Ans. You should clean your filter and follow a proper maintenance schedule to ensure the proficiency of your filter. The filter media should be taken care of because it might get clogged. Gently rinse the sponge or filter pads. Do not rinse the filter media with tap water if you don’t want to destroy the beneficial bacteria colony. Take a bowl of tank water and gently rinse the media in it.
- How often should I clean my aquarium filter?
Ans. The general rule is to clean the filter and your filter media every four weeks (a month). However, to adjust your fish to your tank’s new environment, you should wait at least a week from your last cleaning session.
- Where should a filter be placed in a fish tank?
Ans. The position of your filter depends on the type of filter. The simplest sponge filter or the air-powered unit should be below the water level. You must ensure the rise of enough bubbles for proper filtration.
An under gravel filter is relatively easy to place because it remains under the substrate of the aquarium. However, the perforated plates only go under the substrate; the tubes and the air pump never do.
The HOB or hang-on-back filters are generally placed at a higher position than the water level.
If you have a canister filter, its output must be placed 1.5-2 inches below the water. It should be fully submerged. Otherwise, it can cause noise.
- Why does the flow rate drop in my aquarium?
Ans. The flow rate might drop because of a clogged filter. There might be a blockage. So, the filter foams and media need to be cleaned.
Rinse them gently in the old tank water. Also, if they are not in proper shape, you might need to replace them.
It is better to replace the cartridges of the filters monthly to restore the flow rate.
- How long should my aquarium filter run?
Ans. Considering the fact that your aquarium filter cleans and purifies the water in your tank, you should turn them on every time. Shutting down the filter for a couple of hours might not give you a fruitful result.
You might know that the filter cleans the tank water, removes leftover food, fish waste, and acts as the colonies where the beneficial bacterias stay. They convert the toxic chemical wastes into less harmful chemicals. The filters also oxygenate the water of your tank to keep the fish alive. If you turn down your filter, these subtle details would not be maintained. So, you must keep your filter on every time for the sake of your pets’ health.
