Description
The SunSun HBL-303 Hang-On Filter is the ideal filtration solution for small to medium aquariums (up to 60 Liters). Designed for efficiency and aesthetics, this “Hang-On-Back” (HOB) filter sits outside your tank, keeping your underwater view unobstructed.
Complete Filtration System Despite its compact size, the HBL-303 is a powerhouse. It draws dirty water up, passes it through multi-stage filter media to trap waste and neutralize ammonia, and returns clean, oxygenated water to the tank via a gentle waterfall effect.
Customizable for Your Needs Whether you have a planted tank requiring gentle flow or a community tank needing more circulation, the adjustable flow control knob puts you in charge. It is suitable for both freshwater and marine setups.
Important Usage Note (Priming): This filter is self-priming only after the chamber is filled. Before plugging it in, you must fill the filter box with water. This prevents the motor from running dry and ensures immediate water circulation.
