Weco has been making quality aquarium products for nearly three generations. Established in 1947, Weco was born with the philosophy that a healthy fish is a happy fish. When a need arose to neutralize chlorine and chloramine from municipal water, Weco was at the forefront over 65 years ago. Today, many aquarists and pet stores still teach their customers to "dechlor" their water. The original logo for dechlor still remains and is recognized by many to this day.
