Marine Aquarium Supplements

Marine Aquarium Supplements – Support Coral Growth, Fish Health & Water Stability

Marine fish, coral, and invertebrates need specific minerals to survive and thrive. In nature, seawater provides essential elements like calcium, magnesium, and trace nutrients. To replicate these conditions in a marine tank, regular supplementation is essential. Marine aquarium supplements restore vital minerals and maintain healthy biological function. They help coral build structure, boost colour, and increase resistance to stress and infection. Calcium and alkalinity are key to strong coral skeletons and balanced pH levels. Magnesium supports these processes and helps prevent calcium precipitation. Trace elements and amino acids promote vibrant colours and coral feeding responses. Bacterial supplements improve water quality and reduce waste build-up in reef tanks. Water conditioners and detoxifiers remove harmful substances and improve tank clarity.
