HQJ‑900G – water pump

This submersible power head pump is intended for keepers who need one unit to handle filter drive, water circulation and aeration in freshwater, marine or aquaterrarium tanks. It is the model SunSun uses as original equipment in its own aquariums, so it is built around the brand's aquarium systems.

Why it matters

• Rated at 900 l/h flow, which is the main figure to check when matching it to a filter or circulation need.
• Maximum water lift of 120 cm, so it can push water up to that height from its position in the tank.
• Draws 12 W and is described as energy efficient, with quiet operation.
• Fully submersible and rated for continuous 24/7 operation.

What it works with

The pump supports several roles: circulation, aeration, filling and emptying a tank, and driving a sponge filter for mechanical and biological filtration. It can also power various undergravel and biological filters. Its suitability for a given tank depends on the flow and lift figures above, which should be matched to the filter or circulation setup in use.
