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.
One of the major advantages of this treatment is its ability to neutralize harmful compounds present in tap water, such as chlorine, chloramine or heavy metals. At the same time, it works to stabilize the pH , an essential factor in maintaining a healthy environment.
