About Our CEO - Leo Chen


Leo Chen was born in Ningbo, China, and studied at Massey University in New Zealand. He was deeply attracted by the charm of saltwater aquariums when he first came into contact with it in 2005.


After returning to China, he devoted himself to the research of saltwater aquarium equipment, and founded the OneCove brand in 2010, and developed the first product "I-series" protein skimmer, which was famous at home and abroad, and became one of the first choices of high-end skimmers. Subsequently, to meet the home and abroad demand, he developed the "CR series" calcium reactor, filling the shortage of this product in the saltwater aquarium industry.


In 2014, Leo Chen won the championship in the first CIPS International Aquascaping Competition, and then OneCove products have been winning many awards in the global industry.
