Tropic Marin Reef Actif 60g contains marine biopolymers that bind excess nutrients and other pollutants, leading to their decomposition through specialized microorganisms. This promotes a natural marine microbiological environment in the aquarium and keeps the water exceptionally clear.

The activation of microflora provides the water with many vitamins and other vital substances in an entirely natural way. Corals and shells open better and display their full range of colors. Fish also benefit from the stable bacterial flora and probiotic action, resulting in them becoming strong and showing their vitality with enhanced coloration.
