THE TOP CANISTER FILTERS FOR YOUR AQUARIUM
Canister filters are one of the most popular choices in aquarium filtration. In this article you will read about some of the most popular models on the market.
Aquarium filters come in all shapes and sizes so you can choose the one that is best for your particular aquarium. It is important to keep in mind that certain models are better for certain types of tanks. Sponge filters, for example, are only recommended for hospital tanks and fry tanks because they provide low-suction mechanical filtration that won’t post a threat to sick, injured or young fish.
For larger, fully-stocked tanks, however, a more powerful filter is recommended. One of the most popular types of aquarium filter for traditional freshwater aquariums is the canister filter. Canister filters come in a wide range of sizes to accommodate the smallest to the largest of tanks. Below you will find some basic information about canister filters as well as recommendations for different models.
Benefits of Canister Filters
A canister filter is a self-contained, all-in-one device for aquarium filtration. These devices take the shape of a cylindrical plastic canister (hence the name) which houses one or more types of filter media. Depending on the size of the filter, it may contain multiple media baskets which can accommodate different types of mechanical, chemical and biological filter media. These baskets are layered on top of each other so the water that passes through the filter passes through all of the filter media as well. In comparison to other popular types of filters like power filters, canister filters are a little more work to setup and maintain. However, they are also considered to be more efficient and more powerful. Another benefit of this type of filter is that it can easily be concealed behind or below the aquarium, unlike power filters which typically hang off the back.
Top-Rated Canister Filters
When it comes to canister filters, there are many options to choose from. Below you will find a short review of some of the most popular models on the market.
They Hydor Professional line of canister filters is based on the Japanese style. These filters are rectangular in shape with tight-fitting baskets, superior soundproofing and added efficiency.

Porous biological filter media provides ample space for beneficial bacteria to grow, helping to establish and maintain the nitrogen cycle in your tank. Perhaps the best part about these filters is the price – these filters start at only $90 and top out around $166.

Because the inline water pump can be housed separately from the main device, you don’t have to turn it off to clean or service it!

Many users also appreciate the powerful pump and the flexible media trays.
