This Hydor Koralia Evolution 1500 Replacement Impeller replaces the impeller body for your Hydor Koralia Evolution 1500 aquarium pump. It is very important to select the correct impeller for your pump to ensure proper operation.
Note: This impeller is for the Hydor Koralia Evolution 1500 pump. The label on your pump may state that it is the Koralia Pump Evolution 1400 instead of 1500. However, if the pump label also says "Qmax 1500gph," the pump is an Evolution 1500 pump. Does not fit old style Hydor Koralia 1500 pumps.
