On the Eastern Shore of Maryland we operate the nation's largest indoor coral farm and reef livestock retail outlet. Our facility is the first and only inspected, licensed, and certified coral aquaculture facility in the state of Maryland.

We have invested in the future of our hobby by growing thousands of corals in our own new greenhouse coral farm. This is a working farm where we aquaculture interesting species for future growth and also coordinate and implement cooperative research studies with local universities.

We always stock hundreds of coral colonies, frags, inverts, clams, and fish, plus live rock, live sand, and dry goods. We offer the largest and most diverse selection of marine aquarium livestock in the U.S.

Dr. Mac, a Board-Certified veterinarian, has been a marine aquarium hobbyist since the 1960's and owns and personally manages this new coral research farm.

State Licensed and Inspected Facility

Our facility is open to inspection at all times by state authorities. This facility is now also used and available on a leased basis to government agencies, pharmaceutical companies, and research institutions for the production of first and second generation captive grown corals for research purposes. These companies and institutions require constant quality control and verification of standards.

Maryland's Department of Natural Resources Fisheries Service has granted us an Aquaculture Permit, number 2010-G-010 issued 2-18-2005, as the first facility to "Tank Culture Ornamental Corals".

Our greenhouse frag facility was designed and built by us and was completed in November 2004. We now grow thousands of corals in our facility.

In the first year of coral production in our facility we learned that many larger polyped stony corals and soft corals grew extemely well with very vibrant colors under natural sunlight without any lighting supplementation. Many smaller polyped stony corals also grew very rapidly, but some types lost some color intensity over time as seasons changed and light levels and direction shifted. These corals were grown in the greenhouse and then under metal halide or VHO fluorescent lighting and the colors became more vibrant.

We keep our water quality as near to natural saltwater as possible on a consistent basis including the control of nutrient levels. For example, with new electronic testing equipment we can insure extremely low verifiable levels of phosphate and nitrate in our culture water.

On a daily basis we monitor temperature, pH, salinity, alkalinity, calcium, magnesium, nitrate, potassium, and phosphate levels. These levels are charted and examined to discover any seasonal changes and to make corrections as needed---daily monitoring is critical in a large facility like ours.

Our freshwater source is well water and we ultra purify this water with an elaborate process to insure perfect incoming water quality, this is extremely critcal for a greenhouse type facility. We have found that this is our number one priority on a continual daily basis we monitor our freshwater and always recommend the same for all our customers whatever their freshwater source--good quality freshwater is the key to success in a reef tank!!

To insure you receive healthy livestock we treat our systems monthly for control of flatworms and red bugs and all livestock is closely examined before shipping. We also recommend you quarantine all livestock before placement in your display tank, an acclimation sheet is included with each shipment.

You are welcome to call Dr. Mac to discuss the operation of our facility or visit for a tour during our retail hours of operation.
