In our tank you will float in 800 Lbs of Epsom Salts dissolved in approximately 10-12 inches of water warmed to body temperature. While lying on your back, gravity will bring you to the surface, you will find yourself floating like a cork, making you feel like you are totally weightless. Just relax, breathe and let your mind wander (just remember, your float is all about you!) FLOATING IS GREAT FOR YOUR MIND, BODY & SPIRIT!
