The reason for adding a filter to the fish tank is to get rid of toxins, odors and discoloration in water, including nitrates and ammonia. We also want to add oxygen to the water.
What is filtration?
Filtration is the general cleansing process of a contained body of water.
In nature filtration is accomplished in several ways. For example in a body of water the current will steadily carry unwanted materials downstream. Large amounts of other life forms occupying the waters also help ensure lakes and rivers remain clean.
Unlike natural waters, a fish tank or pond is smaller in size and has no means to rid itself of unwanted materials and chemicals. Filters do this job.
What do aquarium water filters do?
Effective water filters remove excess ammonia, nitrates and dirt and maintain a healthy, aerated environment in the tank.
Aquarium filtration is very important to goldfish care and shouldn’t be neglected. The water needs to be kept free of toxins and clear. If you can’t observe your fish because of the poor condition of the water, then you can’t appreciate them.
There are basically 2 types of unwanted material found in a body of contained water.
- Material tiny enough to pass through pre-filters.
- Unwanted material that has the ability to pass through any filter medium because it’s soluble in water. These water soluble materials include such things as gases and chemical compounds.
Why should I buy a fish tank filter?
Often too much dirt is the cause of death for fish. Reduced oxygen inside the fish tank along with excess nitrates and ammonia suffocate fish.
Poor water condition causes frequent changes to the water temperature which leads to other physical problems for your fish. These may not be immediately apparent.
Colorful aquariums make a room look more vivid and livelier, but as you know it’s more important to maintain the aquarium to keep your fish in good health.
By ‘maintaining’ we generally don’t mean cleaning the aquarium, but feeding the fish properly and preserving the environment in a way that’s fit for the fish to live in.
Some people may already know what’s required, but for beginners you should buy a kit that provides the right set up for the wellbeing of your fish. It shows that you care! An external power filter is a good place to start.
When foreign substances accumulate on the aquarium walls scrapers are used to remove it and then the filters can do their job.
Types of filters
Aquarium filters are classed according to the function that they perform.
Some of the useful fish tank filters are gravel filters, air powered filters, internally powered head filters. Choose filters depending on the type of fish kept in the aquarium.
Sponge filters are the choice as a betta fish tank filter. Bettas don’t like movement in the water. Sponge filters are also a good choice in a tank with fry because they produce very little current and there’s a reduced risk of drawing fry into the filter system.
Bear in mind that some air power filters may not be ideal because they may disturb the layer of gravel on the bottom of the tank. This disturbance throws up a lot of dirt which can quickly overload the filter.

When looking at filters you’ll come across many very complex filter systems. If you boil down their complexity basically, in principle, they all do exactly the same thing.
The power filter suits small to mid size tanks, is cheap and effective.
They’re external units that are easy to install.
Keep in mind, if an aquarium is stocked with a huge number of fish, a more powerful and complex system will be needed than if you were only housing 2 goldfish for example.
When assessing your need for good filtration, relate the filter system to the amount of unwanted materials and garbage that the system will have to cope with. The filter system used directly affects the level of pollution found in a pond or aquarium.
