This group covers nano tanks through the common 55 and 75 gallon sizes. The smallest canisters cost about as much as the next size up, so a filter rated a little above your tank often gives more media for the same money and runs at a gentler setting.

- Fluval 207#1 of 8Full review
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 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.
