Shock risk prompts aquarium pump recall

Two models of Hydor aquarium water pumps are being recalled because of a possible risk of electric shock. The Electrical and Mechanical Services Department had asked consumers to stop using Koralia 2 and Koralia 3 models that bear the batch numbers 644, 651, 703 and 707. A department test had found the pumps could have an electrical problem. Consumers can return them to Johnson Wai Aquarium Supply Company for a replacement or a refund. The company's hotline is 2411-0420.
