Resun Surpass Aquarium Air Pump Air 1000

The Resun Surpass Air Pump (often misspelled as Riesen) is a reliable, energy-efficient series of aquarium aerators designed to safely oxygenate freshwater fish tanks, bubble ornaments, and sponge filters.

Key Safety & Setup Tip

Always position your air pump above the water level of the aquarium. If you must place it below the tank, integrate a check valve (non-return valve) into the airline tubing. This prevents tank water from siphoning backward into the pump during a power outage, saving the motor from water damage.
