Best Aquarium Canister Filters Ranked

A strong value for 20 to 45 gallon tanks: generous media space and low power draw at about the price of the smaller 107.

A convenient, well-built filter for tanks up to 70 gallons, at its best for owners who want a quick-rinse pre-filter.

A small, quiet canister for 10 to 30 gallon tanks. The 207 costs about the same and holds more media, so the 107 makes most sense where cabinet space is tight.

A proven, low-cost canister for tanks of 30 to 55 gallons. Flow is gentle, which suits planted tanks and slow-moving fish.

A budget canister for tanks up to 65 gallons. It costs less than the big names but uses more power and says less about its media space.

A top choice for 55 to 90 gallon tanks, pairing lots of media with the easiest pre-filter cleaning here.

The pick of the 07 range for 50 to 100 gallon tanks, with more media space for its rating than most rivals.

A cheap high-flow canister with a UV light built in, for owners fighting algae who accept sparse published specs.

A durable, plain canister for mid-sized tanks. Newer filters with primers and pre-filters are easier to service for a little more money.

A low-cost way to filter a tank up to 100 gallons. Power use and missing specs keep it behind the premium brands.

The flow king for very large tanks, at the lowest cost per rated gallon. Many owners pair it with a second filter on tanks near its rating.

A premium square canister for tanks up to 160 gallons, with lots of media and thoughtful maintenance features.

A powerful, efficient filter for big tanks, with a handy water-change valve. Treat the 250 gallon rating as generous and size by media need.

A media-heavy filter for tanks up to 160 gallons, for owners who value biological capacity over raw flow.

The most media in one canister here. On tanks near 225 gallons, add a powerhead for flow.
