The highlight of the »blueBase programme« is pool type »Base1«. It offers all the features that make a pool so attractive: little space requirements, a clear-cut design, a light visual pool appearance, crystal-clear water, comfortable in use and maintenance – the classical swimming pool.The biological water treatment makes »Base1« outstanding and unique. The result is crystal-clear water, as pure and clean as in a freshwater lake. Not even a drop of chlorine or the treatment with other chemcal procedures are necessary for this. There are no regeneration zones with plants like in a swimming pond.
