MCES is the largest reef event in Michigan…now in its 11th year! The event is hosted by two clubs…The Mid-Michigan Marine Club and Grand Rapids Marine Aquarium Society. Both clubs are busy making preparations and working on speakers and raffle to make it even better. Last year, MCES brought together over 950 hobbyists from around the state and upper Midwest with 50 vendors from across the country. If you are a reef keeper in the Midwest, you do not want to miss this event!
