Fluval FX4
by Fluval
The FX6's smaller sibling, rated for tanks up to 250 gallons. Shares the same self-priming motor and bottom-drain valve in a more compact footprint. Excellent media capacity for its size, and the lower price point makes FX-series performance accessible to more hobbyists. A popular pick for 75-125 gallon setups.
