3.9/5
A strong value for 20 to 45 gallon tanks: generous media space and low power draw at about the price of the smaller 107.

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.
