Copper plays a key role in coral coloration and health. It occurs naturally in seawater in very small amounts, with concentrations up to 3 μg/l. However, in an aquarium, levels up to 10 μg/l are not critical, as copper is not fully bioavailable. By providing an appropriate dose, this supplement prevents deficiencies without harmful excess.
Thanks to its purified and stabilized formulation , Tropic Marin - Components Cuivre allows a controlled and safe intake. Its 250 ml bottle allows for simple administration: 1 ml per 100 liters of water increases the copper content by 0.5 μg/l. The maximum recommended dosage is 2 ml per 100 liters per day.
In addition to its metabolic role, copper plays an aesthetic role by accentuating the pink and blue hues of corals. For optimal balance, it is often consumed with zinc, chromium and gallium. Simultaneous supplementation is therefore recommended via Tropic Marin ® Block Zinc , which simplifies the intake of these elements.
To ensure a perfect balance in your aquarium, it is essential to regularly monitor copper levels and other parameters using a Tropic Marin ICP analysis . This advanced method allows you to accurately detect deficiencies and adjust your intake accordingly, ensuring a healthy and stable environment.
