Fish Tank Filter Buying Guide

Now that you know which type of filter will best suit you. Now read below and have a depth of knowledge about buying an Fish Tank Filter.

Tank Size

The size of your fish tank is the main factor you need to consider before buying a filter. Because a big tank will need a filter powerful enough to filter the water multiple time every hour. The small tank does not require that much.

On the other hand, all types of filters do not fit in all aquariums. You have to be sure of that as well.

Fish Density

The next important thing is, how many fish your aquarium contains. If the fish population is big you are going to need a stronger filter. Which a tank with fewer fish will not need.

The characteristic of the fish is also important. Some fish are more prone to get messier than others. It does not matter if they are fewer in number. Yet, you will be needing stronger filtration.

Types of Fish

The type of livestock needs to be considered as well. A fish tank that contains shrimps or other delicate fish needs a filter with a slow flow rate. otherwise, they will be sucked into the filter.

On the other hand, fish like hillstream loach need a high flow rate to fully thrive. Some fish are more sensitive to water change than others.

You need to buy filters according to the need of your livestock in the tank to make the most out of it.

Water Quality of Your Area  

What is the condition of the water quality in your area that needs to be checked before buying the filter.

You may have noticed by now that, most of the filters do not have a chemical filtration system. It is because in some areas water has reverse osmosis filtration systems in it. Which do not actually need any chemical filtration.

But if your area’s water contains excessive chlorine or metal then you must have to get a filter with a chemical filtration system.


The filter maintains your fish tank and you need to maintain the filter. Many aquarists overlook this criterion and suffer later. Because, without a proper and regular cleaning routine, the filter will not be efficient for much longer.

Cannister filters are easier to clean than others and wet-dry filters are the hardest. Confirm which one will be easier for you to do the routine cleaning and maintenance.


By now you should have a good idea about filters, their price, and their types. There are so many but consider the things mentioned above and you are good to go.

But do not ignore the necessity of the fish as well as the filter requirements. So that, you can start the new journey on the right foot.
