Block Analysis – Zinc – Tropic Marin

Tropic Marin® Block Zincis a concentrated trace element supplement designed to restore vitalzinc, copper, chromium, and galliumlevels in reef aquariums. These transition metals act as key catalysts in coral metabolism, pigmentation, and overall vitality—bringing out enhanced fluorescence and rich coloration throughout your reef.

Zinc, copper, and chromium are essential for biological and enzymatic functions, playing a direct role in coral tissue metabolism and the development of pocilloporin pigments that make corals glow with brilliant fluorescent tones. Gallium, while less understood, is a naturally occurring trace element in seawater that contributes to maintaining a balanced reef chemistry.

TheTropic Marin® Block Systemensures precision dosing by using an indicator element that allows correlated trace elements—those consumed in fixed ratios—to be replenished consistently. This innovative method ensures even the hardest-to-detect elements remain balanced, maintaining stability and preventing deficiencies that could affect coral coloration and health.

Key Benefits

• Restoreszinc, copper, chromium, and galliumto optimal levels for coral metabolism and fluorescence.

• Promotes deeper, more vibrant coloration through natural pigment activation.

• Supports coral enzyme function and energy metabolism.

• Compensates for elements below ICP detection thresholds via theBlock System.

• Simple and precise dosing—ideal for bothmanual and automated systems.

• Reef-safe formulation with easy-to-use dropper for accurate measurement.
