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

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.

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 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 compact high-flow canister for large tanks. Its media space is modest for the rating, so it suits tanks well under 175 gallons best.
