Dr Tim's Aquatics First Defence Marine

Dr Tim's First Defence 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 Defence also neutralises chlorine and chloramine, buffers against pH changes and detoxifies heavy metals. First Defence should be used when doing partial water changes, during disease treatments and when fish are showing signs of stress.
