Sand Gravel Washing
The HG298 handheld aquarium water changer combines an efficient DC pump with 528 GPH high flow that is ideal for fine sand and coarse gravel. This electric gravel cleaner delivers strong suction to quickly clear fish dung and food residues from gravel. The baffle and filter sponge of the sand vacuum cup prevent small fish, shrimp, and gravel from being sucked in, and block sand and gravel entry to the motor.
Aquarium Cleaning
– When used with the brush head, the handheld water changer effectively wipes off grime on aquarium walls, as well as tough stains settled on the tank bottom and landscape rocks.
– When used with the duckbill suction head, it sucks up leftover fish food, fish waste, and large particle debris at the tank bottom.
-The extended plastic scraper on one side also helps to clean tank walls.

Change Water Quickly
Equipped with upgraded thickened rigid hoses and a handy hose clip, this DC water changer can be stably fixed on buckets and free your hands.
Paired with the outlet hose, it supports two-way water operation: draining dirty water out of the tank and filling fresh water from outside. It enables ultra-low water level pumping down to 4 inches.
3 Water Outlet Modes
-Daily easy maintenance with filter cup is upgraded with a toothed connector at the bottom for tighter, secure hose connection, siphon waste from gravel without draining water, for daily light cleaning of small tanks with brush and nozzle scraper attachments.
-Filtered change with filter cup + hose, traps large debris during draining, preventing hose clogs and messy spills, for deep substrate cleaning and thorough removal of heavy tank dirt.
-Fast change with outlet connector + hose for quick water removal and add water, can quickly drain/refill.

Anti-clog Design
The hygger 298 water changer is equipped with a safe DC motor for quieter running with less vibration and lower noise. The unique coverless-free impeller enables 360° all-round water spinning to boost water flow. It effectively prevents sand jamming and reduces clogging and sudden shutdown failure greatly, and fits both fine sand and coarse gravel substrates.
Stable Handheld Use
Built-in air release valve at the 3-way tube automatically exhausts trapped air and vacuum inside the pump and tubes. It effectively fixes the common no-suction problem when turning on the pump before putting it in water for more stable performance.
Note: A slight water spray from the top is normal during air venting.
