Hydor Koralia Water Circulation Pump
Moving water plays an important role in creating a healthy aquarium environment. It provides vital circulation that helps introduce oxygen into the water and releases harmful gasses like carbon dioxide. Without good water movement, biological filtration is impeded and toxins such as ammonia and nitrite can climb to dangerous levels. Also, areas with poor water movement become stagnant and develop "dead spots" where organic debris settles and create the ideal location for nuisance algae to grow.

New water circulation option
The use of a powerhead is the easiest way to improve water movement in an aquarium. However, conventional powerheads are rigid and direct water in a limited fashion. The submersible Hydor Koralia propeller pump offers expanded water circulation options. This dynamic circulation pump directs vital water movement to areas of your aquarium never possible with conventional powerheads. The secret is its special magnetic base and articulating ball joint system. This allows a full, 360-degree range of movement to revitalize hard-to-access "dead spots" in your aquarium. Its patented propeller design generates water flow that is both powerful and delicate, making the Koralia a great choice for any aquarium, especially reef aquariums. Best of all, these units boast extremely low energy consumption, for virtually no heat transfer.
