Walking into Marine Concepts Inc. in Wheeling, Illinois, you'll find one of the Chicago suburbs' most respected saltwater and freshwater aquarium operations — a shop that doubles as a full-service aquarium company led by Dave and his dedicated crew, including team members Carlos and Sergio. The retail space is notably clean, stocked with a rotating selection of corals, reef fish, anemones, and marine livestock at prices reviewers consistently call reasonable.
Dave makes a point of sourcing new corals regularly, and customers note he'll go out of his way to track down specific specimens for your personal tank. What sets Marine Concepts apart is the depth of their service work. They handle everything from nano reef transfers to 250-gallon high-end coral showpieces, building custom tanks with stained maple cabinetry, reef-grade filtration systems, and low-profile lighting setups tailored to each client's space.
One customer describes having their entire 150-gallon reef tank designed, built, and installed with meticulous attention to protecting the home during the process. Another recounts how Dave and Carlos moved and rearranged multiple tanks, even taking fish, corals, and live rock back to the shop overnight when water temperature wasn't ready — a level of care that speaks volumes about how seriously they treat livestock welfare. The service side extends to ongoing maintenance for both residential and commercial clients.
Multiple reviewers mention biweekly tank cleanings that transform their aquariums into show-quality displays, with some relationships spanning over a decade. They've completed government projects and outfitted office spaces, earning repeat business from clients who started with one tank and came back for a second. Marine Concepts also ships livestock and supplies nationwide through Marine Concepts Supply, their online arm, making their coral and fish selection accessible beyond the Wheeling area.
For anyone in the northern Chicago suburbs looking to start a saltwater reef tank or elevate an existing setup, Dave's combination of hands-on expertise and genuine passion for marine animals makes this shop worth the visit.

Dave and his crew setup a beautiful state of the art 150 gallon reef tank in my home. He took care of every detail from the cabinetry which was a custom stained maple stand, a reef filtration system and low profile lights. Dave and his crew were very professional and took great care during the installation making sure everything was protected and clean. I would highly recommend Marine Concepts for any new aquarium and maintenance.

Marine Concepts is all about customer service and doing things correctly. Dave is the best. He setup and started our new aquarium and it is absolutely thriving and beautiful. We could not be happier with our tank, the service, and the selection of fish, corals, anemones, and equipment. Our aquarium is running perfectly and has changed the entire feeling of the room we have it in. Also, they ship everywhere in the country through Marine Concepts Supply. Whatever you need they ship expertly and safely. Again, amazing customer service and selection of whatever you might need for your aquarium.
