Safe for corals and other invertebrates
First Defense was developed to help hard and soft corals adapt to new environments by removing environmental stressors.
Changing the environment of a coral causes stress that can weaken their immune system and lead to disease. First Defense is scientifically designed to provide stress relief and support the immune system, helping corals cope with stress due to bagging and shipping from the store to your tank, water changes, disease treatments, and other environmental changes.
Directions: Shake well before using.
Dosage: Add 5 ml per 10 gallons of aquarium water.
