Tropic Marin Reef Actif 60g

Reef Actif is a natural, marine-derived powder additive that helps maintain stable water conditions between water changes. The biopolymers within bind excess nutrients and pollutants, making them available for beneficial microorganisms to process — promoting a healthy marine microbiology and keeping aquarium water crystal clear. As the microflora becomes active, corals and invertebrates often show improved vitality, fuller opening and enhanced coloration, while fish benefit from a more balanced, stable bacterial environment. Reef Actif works both as an adsorbent (clearing dissolved organics) and as a gentle “food” for beneficial bacteria, supporting nutrient cycling, improving skimming performance, and reducing organic waste buildup.

Usage Guide: Add one level measuring spoon per 500 L of aquarium water once a week (or up to three times a week max) — stir the powder into a small amount of aquarium water, then disperse it evenly across the tank water.
