First Defense Helps Fish Adapt to New Environments

First Defense contains a mixture of vitamins and immunostimulants that work together to help fish and other aquatic organisms adapt and cope when introduced to new environments and stress that can occur with poor water quality conditions.

First Defense also neutralizes chlorine and chloramine, buffers against pH changes and detoxifies heavy metals. First Defense should be used when doing partial water changes, during disease treatments and when fish are showing signs of stress.
