Hydor Koralia EVO 4400 Water Circulation Pump

Hydor Koralia EVO 4400 Water Circulation Pump

The Hydor Koralia EVO 4400 Circulation Pump provides powerful, natural water movement within both marine and freshwater aquariums. With a maximum flow of 4,400 L/h, it improves oxygenation, nutrient distribution, and detritus suspension—supporting a healthier tank environment for corals, plants, and fish.

This energy-efficient pump runs on just 4.5 watts, thanks to its gear-driven design and low-draw motor. It features a detachable cable protector to safeguard marine life and components, and a fine-mesh intake guard to reduce debris intake and ensure longevity.

Its patented magnet-suction cup mounting system secures the pump to glass up to 15 mm thick and provides a stable anchor point. The ball-joint nozzle allows 270° adjustable flow for directing the current where needed. Quiet operation and durable, corrosion-resistant construction make the EVO 4400 ideal for aquariums between 250 and 500 L (freshwater) or 160–275 L (marine).
