What to consider when buying the best filter for small tanks?
For small aquariums under 20 gallons, it is not easy to find a filter, and it is more challenging to choose a best small aquarium filter.
For any aquarium, a filter is very important and for a small tank, it is even more important to clean the tank. The reason is that once a small aquarium is contaminated, it will be very quickly, the whole tank will become polluted, leading to the death of the tank inhabitants.
But don’t worry, we’ll give you a buying guide so you can find your own best filter for aquariums under 20 gallons (in case you don’t like the 5 products we have suggestions above).
Things you should consider before buying any filter are:
As mentioned above, a small aquarium will be very polluted quickly once there are any contaminants in the aquarium. So you need a filter that is strong enough and has enough power to do your job well.
You also should not choose filters that are too powerful for the small size of the tank. Large capacity will create a large flow rate, it will affect the small residents in the tank and above all, it will cause waste for you.
A reasonable capacity for the size of the aquarium is able to create a flow rate of 4 times the capacity (at least). You should calculate carefully to be able to choose a product with the most appropriate capacity. Never choose a product without careful calculations.
For any device, maintenance is needed to maintain the highest life expectancy and the best quality. And an aquarium filter is no exception. You should also build your own maintenance routine because the quality of filtration depends on your maintenance.
If you don’t have a lot of time to maintain regular maintenance then you should choose filters that require low maintenance and require little maintenance. Or you can also choose filter indicators to indicate when you need to clean the filter.
Additional features such as indicators may cost a bit of money, but this is a necessary feature if you do not have too much free time to care about the aquarium.
You should never choose a filter based on price criteria. Well-known brands always cost a bit higher than other products of the same quality. It is a profit problem that perhaps our consumers can understand implicitly.
So to save your budget, you should take some time to search for products with good specifications, maybe of some famous brands, little known.
And you should never choose the most expensive filter because it is not necessarily the best, the best filter is the most suitable for your aquarium.
Warranty is also one of the privileges for customers so that you should not ignore this benefit for you. The extensive warranties are always a good insurance for your investment.
Usually current filters come with a 1-year warranty, but there are also manufacturers that extend this period. Some of the same quality but with a better warranty should be your choice.
