The tank is filled with 10 inches (25 cm) of water which contains enough dissolved Epsom salt to create a specific gravity of approximately 1.25–1.26, enabling a person to float freely with their face above the water. In order to reduce thermal sensations, the water in the float tank is maintained at approximately skin temperature, around 35 ...

In a well designed system, the existing water in the raceway is largely replaced by new water when the same volume of new water enters the raceway.
