Aquarium Canister Filters

By

Canisters are my choice for tanks forty gallons or larger, especially for show tanks, as they can be completely concealed and not detract from the appearance of the aquarium. Because canister filters force the water through the filter media, they are particularly good at removing particulate matter. Canister filters are adaptable to a variety of conditions.

By changing the type and volume of various media, it is possible to create a custom filtration system for the needs of your aquarium. Water can be polished using diatomic sleeves, extra rings or sponges can be added to encourage bacterial colonization for increased biological filtration, or additional mechanical media can be used for aquariums that have a lot of particulate waste. Chemical filtration can be modified by using special resins to remove dangerous toxins.

Eheim Classic

Eheim Filter

Boasting a high throughput rate and durability, the Eheim is the quietest canister on the market. I like the compact design and easy to handle latches. The classic series has been on the market for years and has performed reliably. Replacement parts are easy to find, which is a big plus. My only complaint with this series is the lack of self-priming. However, they do provide tips on how to prime the filter, and it isn't too difficult. Although somewhat pricier than other brands, I've found that over time Eheim out performs others. It's definitely a solid product.

The Hagen Classic series are guaranteed for 2 years. Models include:
2211 - flow of 60 gallons per hour, tanks up to 40 gallons
2213 - flow of 116 gallons per hour, tanks up to 66 gallons
2215 - flow of 164 gallons per hour, tanks up to 92 gallons
2217 - flow of 264 gallons per hour, tanks up to 159 gallons
2260 - flow of 635 gallons per hour, tanks up to 395 gallons
2262 - flow of 900 gallons per hour, tanks up to 560 gallons

Fluval 05 Series

Fluval 305

Fluval produces one of the most economic, yet efficient, multimedia filters available. Learning a lesson from their older models that were too tall and unwieldy to service, the redesigned models are compact, and sport larger latches similar to the Eheim products. Self priming has been added, which is a big improvement over previous models. However, they still tend to be noisy if not properly filled. In spite of that, you can't go wrong with a Fluval.

The 05 Series are all guaranteed for 3 years. Models include:
201 105 - flow of 125 gallons per hour, tanks up to 25 gallons
A206 205 - flow of 180 gallons per hour, tanks up to 40 gallons
A211 305 - flow of 260 gallons per hour, tanks up to 70 gallons
A216 405 - flow of 340 gallons per hour, tanks up to 100 gallons
A218 FX5 - flow of 925 gallons per hour, tanks up to 400 gallons

HOT Magnum

Magnum Filter
Pricegrabber
HOT (Hang On Tank) Magnum balances price with some of the best features in a canister. It is self-priming, quiet, and offers convertible filtration modes, including the option of adding a matching Bio-wheel system as well as a diatomic sleeve to remove even the smallest particles from the water. The clear canister makes it easy to see the condition of the filter. Optional gravel cleaner is a nice perk to an all around great package.

Currently two models are offered, HOT Magnum and HOT Magnum Pro, the difference being the addition of a Bio-wheel system to the Pro system. Both are rated at 250 gallons per hour, for tanks up to 50 gallons
