Stream pump designed for marine aquariums over 100 liters (26.4 US gal) This compact and energy-efficient pump (28 W, max. 8,000 l/h / 2,113 US gal/h) facilitates natural water agitation in your marine aquarium. Water plays a crucial role by transporting heat energy, oxygen, and CO2, as well as carrying byproducts of metabolism. Improved mixing of aquarium water results in more consistent water parameters, making it easier to fine-tune filter devices like skimmers. The SPM 8000 can be securely mounted to the aquarium glass using the included clamping lever suction cup. The ball joint on the clamping lever suction cup ensures the pump enjoys a wide operating range.
