The purpose of filters on aquariums is the removal of excess food, any decaying organic matter, floating particulate and dangerous chemicals, and, of course, the fishes’ waste products.

Fish constantly excrete waste, They do so as they swim around in the water. If this is not taken away, the toxins will rapidly mount up. The concentrations can easily get high enough to poison the fish. The early stages are known as ammonia stress. When this stress becomes fatal, it is called ammonia poisoning.

Particulates in the water and any decaying organic matter can quickly lead to cloudy aquarium water. As you can see, if you have fish, it’s extremely important to have a filter for your fish tank:

How Filters Clean Water

There are three ways in which filters work either separately or together. They are Biological, Chemical, or Mechanical.

Biological filtration is necessary for all aquariums. It reduces the amount of maintenance that is needed. But, both mechanical and chemical filtration have reasons to exist too. Mechanical filtration keeps water clear. Chemical filtration takes care of problems with source water and can remove certain toxins introduced to the aquarium system.

You need to be aware that water can look crystal clear but still poison your fish. On the other hand, it can also look murky and dirty but be completely safe!

As carbon attempts to absorb any chemicals from the water, it can start the release of toxins not easily bound up by the carbon. This can take one of two forms. The substances may be absorbed from the water. Alternatively, the substances could result from chemical reactions related to the carbon.

This is why it is so important to regularly replace anything containing carbon. However clean a tank is, it’s advisable to replace the carbon-containing media at least every two months. Messier tanks may require more this to be done more often.

It is vital for the health of the fish in your fish tank that they are provided with enough filtration. Not only can this filtration make your tank look a lot smarter but it will also significantly reduce the care that is needed to maintain healthy and happy fish.

Indeed, changing 10-15% of the water once a week with a filtered system is much cleverer than changing 80-90% each day that is needed for unfiltered systems to remain viable.

But installing a filter or filters provides no excuse for shirking on all-important tank maintenance. The fish in your tank will still require to be fed properly, the tank will still need to be cleaned, the water will still have to be changed, and you will still need to spend time regularly inspecting the tank and its inhabitants for signs of stress, abuse, disease, and any other associated problems.

There are numerous varieties of filters. These include both models that can be submerged along with non-submersible examples. To select the best fish tank filter make sure it will match the filtration needs of your particular tank. You also need to ensure the filtration you choose is appropriate for the fish you keep.
