Tropic Marin - ICP & Blocks

The Tropic Marin® Block System is an advanced series of concentrated trace element supplements designed to restore essential microelements in reef aquariums with unmatched precision. Each Block targets a specific group of elements—such as halogens, transition metals, or alkaline earths—that are consumed together in fixed ratios by corals and other marine organisms.

Using a unique indicator element system, Tropic Marin® Blocks ensure balanced dosing even when trace levels fall below ICP detection limits. The result is a stable, well-balanced reef environment that supports vibrant coloration, healthy growth, and improved skeletal structure—all while simplifying trace element management for serious reef keepers.
