Tropic Marin REEF ACTIF 60 g

Tropic Marin® Reef Actif consists of a blend of natural organic substances, predominantly of marine origin. The biopolymers in Tropic Marin® Reef Actif bind excess nutrients and other pollutants, making them available for breakdown by specialized marine microorganisms. This promotes a healthy marine microbiology in the aquarium and keeps the water exceptionally clear.

By activating the microflora, numerous vitamins and other vital substances are added to the water in a completely natural way. Corals and mussels open more readily and display their full splendor of colors. The fish also benefit from the stable bacterial flora and the prebiotic effect – they develop robustly and demonstrate their vitality through flawless coloration and natural behavior.
