"This is the only water conditioner I use. It works great...it's easy to use, it gets rid of the chlorine & chloramines, it reduces the stress on my fish when doing water changes & adding new fish, & it helps my fish heal. When I first got my 6 Neon Tetras, their fins were nipped pretty bad & in week or so after adding Stress Coat they had healed up...it's amazing how fast this stuff works, I highly recommend it!"
