First Defense was developed to help fish adapt to new environments by assisting the fishes’ natural immune system. Changing the environment of a fish causes stress that robs fish of essential nutrients and can weaken their immune system. First Defense is scientifically designed to provide stress relief and support the immune system, helping fish cope with stress due to bagging and shipping from the store to your tank, water changes, new fish additions, disease treatments, and other environmental changes. First Defense also contains buffers to help maintain the water pH. Further, First Defense detoxifies heavy metals and removes chlorine and chloramines.

Looks very snake oily to me. I mean, detoxifies heavy metals… are heavy metals a large problem in most reef aquariums? You’d think the inverts would show it first if they were. Adds helpful buffers… isn’t this normally addressed by a normal Ca/Alk. Dosing regimen? Removes chlorine and chloramine… these shouldn’t be in the tank water to begin with! Supports the immune system with vitamins and immunostimulants… have they shown there to be a lack of these specific ‘vitamins’ in normally maintained reef aquariums? The claim to be “Scientifically designed” is most dubious of all.
