Care Facts

Currently there are no key facts available for this product.

Next generation Koralia pumps boast greater energy-efficiency and enhanced features. The Hydor Evolution design and technology guarantees a continuous and powerful water flow which can be directed freely thanks to the special sphere shaped connection to the exclusive combination suction cup and magnet support. High performance, low energy consumption and quick and easy maintenance. Patented magnetic base with articulating ball joint allows full, 360-degree range of convenient pump positions. Direct vital water movement to areas of your aquarium never possible with conventional powerheads. Unlike the non-Evolution Koralia pumps, the Koralia Evolution can be connected to a Wavemaker.


  • New and improved vibration absorbing magnet and suction cup support. The combination suction cup + magnet can safely hold Koralia positioned in tanks with glass (or acrylic) up to 15mm inch thick.
  • Sphere joint: adjustable flow direction
  • Smaller design that older style Koralia pumps with similar flow rates
  • New shaft-less impeller technology
