Natural immune support for fish and corals

What makes First Defense so powerful is its balanced blend of essential vitamins and natural immune boosters . These ingredients boost the natural ability of aquatic organisms to defend themselves against external aggressions. The result: your fish are more vibrant, more colorful, and above all, less prone to disease. It is a valuable ally for strengthening the resilience of tank inhabitants , especially after treatment, acclimatization, or a major disturbance. By preventing rather than curing, this treatment makes your aquarium more stable and peaceful in the long term.
