For treating aquarium water between water changes.

Tropic Marin® Reef Actif is made up of a mixture of natural organic substances of predominantly marine origin. The biopolymers in Tropic Marin® Reef Actif bind excess nutrients and other pollutants and cause them to be degraded by specialised marine microorganisms. This promotes a natural marine microbiology in the aquarium and keeps the water extremely clear.

By activating the microflora, numerous vitamins and other vital substances are added to the water in a completely natural way. Corals and bivalves open better and reveal all their rich colouring. The fish also benefit from the stable bacterial flora and the prebiotic effect – they develop robustly and show their vitality through flawless colouring and natural behaviour
