Abstract
Abstract A therapeutic pool system whereby a safer and more comfortable air circulation system is provided. In detail, it comprises a fluid circulation system which circulates the fluid, usually water, from the pool through a skimmer, filter and heater back to the pool. In addition, there is an air circulation system whereby air is taken from above the water in the skimmer, intermixed with the circulating water and returned to the pool to provide a healthful, comfortable experience for people using the pool.
