Don't listen to these people. Bang Guy says he thinks stress coat is harmful and I trust him. He's been around for a long time. These two as you can see are new. The mods should do something about people giving bad information intentionally like above ^^^^. Go to the search tab and type in stress coat and read a little on it.
If you are using RO/DI, distilled, or even water that has set out overnight you do not need to add any type of stress coat (dechlorinator). If you have a skimmer, adding stresscoat will make it go beserk.
i always add melafix to my tanks when adding or moving my fish for 3 days not only does it help with rebuilding the natural slime coat of fish it also helps reduce the accual stress of the fish,in a natural form and yes its reef safe.also used for minor bacterial and fungal diseases that could be present on new arrivals. my experience with this product has been over 4 1/2 yrs using it 100% survival rate of newcommers that were dosed when adding to the tank.50% survival rate for new commers not dosed.
