Hydor Koralia Pumps
The search for a versatile, economical and easy to use water pump for circulation in the aquarium is over. The new Hydor Koralia series of submersible water pumps fill the need. Available in four sizes, these pumps use a unique suction cup/magnet mounting to allow you to place them wherever you prefer in your aquarium, eliminating any dead spots. The magnets will work on glass up to 1/2" thick and the highly adaptable sphere enclosure uses a ball joint assembly to allow you to angle the water flow exactly where you want. The low wattage Koralia pumps have high flow rates that are achieved by their unique "prop" design impeller. Unlike traditional powerheads, this high flow is dispersed over a larger area, not as a "jet" outlet. This propeller is self correcting to maintain the proper spin and the sphere enclosure prevents any damage to curious fish. Unit has a 2 year warranty.
