3. Penn-Plax Cascade Aquarium Canister Filter – Premium Choice

6. Hydor Professional External Canister Filter
The Hydor Professional External Canister Filter is a premium-priced canister filter available in five sizes from 20-150 gallons. This product can be used by beginners, but it is professional grade, with the price tag to match. It can be used in freshwater or saltwater tanks.

The 150 model has two media trays, the 250 model has three media trays, the 350 and 450 models have four media trays, and the 550 model has five media trays.

8. Zoo Med Nano 10 External Canister Filter
The Zoo Med Nano 10 External Canister Filter seems cost-effective on the front end, but it is only made for nano tanks up to 10 gallons. It is safe for use in freshwater and saltwater setups.
This small canister filter uses 3-stage filtration and includes filter media for you to get started. It also features a built-in spray bar. This product is intended for beginners and is made to be easy to use and prime. It does not have a self-priming feature, though.
It is compact so as not to take up too much space near a nano tank, but it can appear quite large and is difficult to hide near tanks smaller than 10 gallons. It is intended to sit at the level of the tank and the hoses are too short for it to sit below tank level. It has an adjustable flow-control system and is easy to open to access the filter media.
9. Aqueon QuietFlow Canister Filter
The Aqueon QuietFlow Canister filter is a premium-priced product available in three sizes from 55-150 gallons. While this is a canister filter, it includes a HOB water polishing unit to help ensure water returned to the tank is clear. This unit requires a water polishing cartridge. This system takes up the same amount of tank rim space as a HOB filter.
This 3-stage filtration system is customizable but does include filter media to get started. It includes a spray bar and water director. This system may wear out after a few months of use and does have some noise with operation. It cannot self-prime.
10. Odyssea CFS 130 Hang on Aquarium Canister Filter
The Odyssea CFS 130 Hang on Aquarium Canister Filter is for filtration of tanks from 30-40 gallons. It is cost-effective for this size but does require strong glass or a rim to hang on.

This 3-stage filtration system is intended for use with a filter pad, coarse sponge, and bio balls, which are included in the kit. The filter media can be customized to your preference. This system does require manual priming but is easy to use and set up. The motor in this filter may wear out within a few months and many of the plastic pieces are prone to breaking or failing. If the motor is still working after a few months, it often causes the filter output to slow significantly. The filter nozzle on this system is small, meaning it can clog quickly with plant materials or waste.
After reading these reviews, do you feel less intimidated by canister filters? Many of them are beginner-friendly and easy to use.
