Your aquarium fish deserve to live in a clean and healthy environment, but what does that mean for you? Routine water changes are important, of course, but what’s more important is the day-to-day filtration that removes waste and toxins from the water column before they can have a negative impact on water quality. Choosing the right filter for your aquarium is essential because it provides that constant filtration that is boosted by your routine maintenance tasks.

Now that you have a better understanding of what an aquarium filter does, you’re ready to start shopping around. Keep in mind that most aquarium filters come in different sizes, so choose the one that is best for the size tank you have. Also remember that it is better to size up than to size down – don’t try to save money by purchasing a smaller filter than your tank needs.

Here are our top picks for the best aquarium filters for a beginner tank:

If you’re really not sure where to start when it comes to choose an aquarium filter, you have two options. One option is to purchase an inexpensive filter – if you decide not to continue the hobby, you won’t have made a significant investment. The other option is to purchase a high-quality filter larger than you really need so if you decide to upgrade your tank later, you don’t need to buy a new one. Whichever option you choose, there is sure to be an appropriate choice on the list above.

There are many different kinds of aquarium filter, so take the time to consider your options before you pick. To some degree, any filter rated for the tank size you have should work, but certain filters provide more benefits than others. Before you start shopping, take the time to learn about some general things you should look for in an aquarium filter.

Here are some things to look for in an aquarium filter.

  • Style – Aquarium filters come in several models, both internal and external. External filters are typically recommended for larger aquariums and hang-on filters are the most budget- and beginner-friendly option.
  • Type of Filtration – Look for a filter that offers mechanical and chemical filtration at a minimum. Mechanical filtration involves removing solid waste (like uneaten fish food) while chemical filtration removes toxins and chemicals. Biological filtration supports the growth of beneficial bacteria which help maintain the nitrogen cycle.
  • Size/Strength – The larger your tank, the bigger the filter should be. Pay attention to the size range each filter is rated for and consider buying one larger than you need.
  • Filter Media – The filter media are what provide the actual filtration, so pay attention to what type each filter uses. If there is extra space to add optional extra filter media, even better.
  • Maintenance – In addition to performing water changes to remove accumulated ammonia and other toxins from your tank, you’ll also need to maintain your filter. Consider how easy it will be to change the filter media and whether there are any small parts that might be hard to clean.

Though all aquarium filters are not created equal, most of them do offer three-stage filtration. If you choose a filter that doesn’t incorporate biological filtration, you might want to consider taking additional steps to cultivate beneficial bacteria in your tank.
