Fluval 107
#3 in Up to 75 galFull review
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.

Penn-Plax Cascade 700
#5 in Up to 75 galFull review
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.
