Do Gellert Spa pools contain chlorine? The answer is yes and no.
Hot thermal pools (that is pools using the natural hot spring waters pouring from underground thermal reservoirs) are completely refilled every day and they do not contain chlorine or any other cleaning agents to preserve the high-quality of the naturally rich thermal water. This way the thermal waters can offer maximal beneficial effects for the visitors every time.
Swimming pools and other cool water pools are infused with a minimal amount of chlorine and cleaning salts to ensure that pool waters met health and safety standards. Since the amount of chlorine is kept on a minimum level, the smell of chlorine can be hardly detected.
Difference between Thermal and Swimming pools
Thermal pools of Gellert Spa are hot and richer in minerals, so they offer more recreational and hydro-therapeutical benefits than the cooler pools with less mineral content.
Nevertheless, the recreational and hydro-therapeutical benefits of the outdoor pools, including the swimming pool are potentially stronger compared to regular pool waters.
