Originally posted on https://www.tropicalfishcareguides.com/fish-tank-filters/canister-filters-with-uv-sterilizer/

7.2 million people across the United States have at least one fish tank in their homes.

If you’re among these fish owners, you should already know about the importance of a filter. Filters keep your fish’s water clean and safe for them.

Canister filters are just one type to choose from, and we’re going to go over a few reasons why you might choose one, and our top seven picks.

Keep reading to find out more about the best aquarium canister filters.

Why Use a Canister Filter

Before we get to our top picks, let’s go over the top three reasons you want to use one for your tank.

Work Well

First and foremost, canister filters are great at removing particulate matter from the tank. This alone makes them a great choice, especially if you have a tank that’s 40 gallons or more.

Customizable

Not all bacteria are bad, which is why fish experts add special media to their filters that provide ideal living environments for beneficial bacteria. Filter media comes in a variety of sizes, materials, and shapes.

The benefit of using a canister filter is that most are designed to hold several different types of media if you want to try different combinations. This allows you to provide the right home for the bacteria that will most benefit your fish.

Hideable

If you put a lot of work into making your tank look spectacular, it’s disappointing to ruin the look with a filter. That’s why people that create show tanks love canister filters.

Because the bulk of the filter is on the outside of the tank, it’s easy to hide it so you can simply enjoy the beauty of the fish and decorations.

What is UV Sterilization?

Now let’s take a moment to talk about UV sterilizers and why you would want a canister filter that has one. A UV sterilizer uses ultraviolet (UV) light to kill or incapacitate microorganisms.

Traditional filters rely on physically removing bacteria from the fish tank. However, that doesn’t guarantee the tank will remain clean as some bacteria can slip through the cracks.

A UV light prevents any of these harmful microorganisms from escaping and getting back into your tank, keeping your fish happier and healthier. It can also mean you can go longer before cleaning your aquarium.
