Got New Fish?  First Defense will help them adapt to their new home, helping our aquatic friends boost their immune system and relieve stress.

First Defense should be used when doing partial water changes, disease treatment, or when fish are showing signs of stress.

Environmental changes can be highly stressful for fish, and can strip them of nutrients which can weaken their immune system. With a mixture of vitamins and immunostimulants, First Defense helps fish, as well as other aquatic livestock cope and adapt to their new surroundings, relieving stress that occurs from sudden changes of environment and water quality conditions.  Less stress, the less likely the fish will become succumb to illness.

First Defense can also be used to neutralize chlorine and chloramine, buffers pH from swinging, and detoxifies heavy metals.
