Functions of Fish Tank Filter System
Before you can learn more about which fish tank filter to buy, it is always better to start from the basics, so we will first discuss the different functions of a fish tank filter.
The functions are categorized into three major classifications to help you choose the right one.
Fish produce ammonia from their gills as they breathe, and also as part of the waste released from their bodies. The ammonia needs to be removed from the tank frequently, as it is quite toxic to the fish.
The use of a filtration system will help in the elimination of the fishes’ bodily wastes from the tank. Sometimes you might find the fish dying from the ammonia accumulation, but this is something that can be easily avoided.
It is common to have debris in a fish tank, due to excess food fed to the fish and other dust particles from the room. The mechanical process of a fish tank filter is meant to remove this debris and any other visible waste from the tank.
Once the water is purified, the tank will contain the clean, clear water both you and your fish prefer. Having a clean and well-aerated tank will promote good health for your fish.
The water that we rely on for drinking and cooking comes from different sources. Some sources might contain hard metals or other materials which might be harmful to the fish. This creates the need for a filter that can remove such materials from the water.
Different types of filters will have different methods for cleaning up the impurities. Once they are removed, the fish will be surrounded by clean water in which they will be able to thrive.
