Marine elements are the core supplements used to replace what corals and other invertebrates consume every day, keeping your reef stable and growing. This includes essentials like calcium, alkalinity and magnesium, along with important trace elements that support colour, growth and overall health. Used alongside reliable test kits (or ICP testing) and, ideally, a dosing pump, they help you maintain consistent levels instead of chasing swings. With the right element regime in place, your corals can build strong skeletons, show better colouration and thrive long-term.
