Description

Maintain cleaner, clearer, and continuously circulated aquarium water with the SunSun HBL-403 HOB Filter 400 LPH. Designed with a compact hang-on-back structure, this aquarium filter provides efficient daily filtration while keeping most of the unit outside the tank. This space-saving design leaves more room for fish, aquatic plants, decorative elements, and aquascaping materials.

With a water flow capacity of up to 400 litres per hour, the filter continuously draws water through its filtration chamber to help collect fish waste, uneaten food, loose plant matter, and suspended particles. The steady circulation also helps reduce stagnant areas and distributes filtered water more evenly throughout the aquarium.

The filter chamber can accommodate suitable media for mechanical, biological, and compatible chemical filtration. Mechanical media helps trap visible debris, biological media provides surface area for beneficial bacteria, and chemical media may help reduce unwanted odours, discolouration, and dissolved impurities when required.

The SunSun HBL-403 is suitable for freshwater aquariums, planted tanks, shrimp tanks, community fish tanks, and decorative aquascaping setups. Its accessible external filter chamber makes routine cleaning, media rinsing, and replacement more convenient.

Usage Note

Install the filter securely on the aquarium wall and keep the intake section below the water level during operation. Fill the filter chamber with aquarium water before switching on the unit to help it begin circulating water properly.

Clean the intake pipe, mechanical filter media, and filter chamber regularly to maintain consistent water flow. Rinse biological media gently with removed aquarium water instead of chlorinated tap water to help preserve beneficial bacteria.

Avoid replacing all biological filtration media at the same time, as this may reduce the established bacterial colony. Always switch off and unplug the filter before cleaning, repositioning, or performing aquarium maintenance.

Keep the electrical plug, socket, cable connection, and other electrical components away from water.
