Reef keeping is filled with specialized terminology, scientific concepts, and industry jargon that can be difficult to navigate for new and experienced hobbyists alike. Our Reef Glossaries were created to serve as a reliable reference library for the reef aquarium community.

From coral biology and water chemistry to aquarium equipment, fragging techniques, and reef ecosystem terminology, these glossaries are designed to help hobbyists better understand the concepts that influence coral health and long-term aquarium success.

As reef keepers and reef substrate manufacturers, we believe education plays an important role in responsible reef keeping. Understanding the language of the hobby helps aquarists make better decisions, troubleshoot problems more effectively, and create healthier environments for their corals.
