Swimming pool, Whirlpool, Pond & Biotope


reduces use of chemicals & chlorine

The special consistency of GRANDER water significantly reduces the susceptibility to germs and thus sustainably reduces the need for chemicals & chlorine.

reduces unpleasant odors

At the same time, revitalized water according to Johann Grander naturally reduces the unpleasant odors associated with the use of chlorine and chemicals.

reduces maintenance & cleaning effort

The use of GRANDER water revitalization reduces limescale deposits, rust formation, silting and sedimentation and thus massively reduces your maintenance & cleaning effort.

saves fresh water

GRANDER water can remain longer in your pool, swimming pool, whirlpool, pond or biotope due to its better durability and thus reduces the necessary fresh water supply.

protects the technology

GRANDER water protects your systems and technical equipment, thus extending their service life and reducing your investment requirements.

    Customer experience

    • GRANDER in the pond for a sustainable biological balance

      When we think of GRANDER in the kitchen, the first thing that comes to mind is certainly drinking and cooking water. However, star chef Boris Rommel has had another positive experience in his restaurant at Schlosshotel Friedrichsruhe. GRANDER water revitalization ensures that appliances used daily, such as dishwashers and combi steamers, run much better and, for example, hardly build up any limescale. The result: less maintenance, optimized performance.

    • Lake Kaltenbrunn Successfully Revitalized Since 1999

      Nestled between rolling hills, Lake Kaltenbrunn is an idyllic and scenic bathing lake close to the Upper Bavarian municipality of Prem, located between Halblech and Lechbruck. Eleven hectares large, it is a favorite spot for many people from Prem and its surroundings, who come to swim or fish.

    • Family Kovacs Walter in Hall near Admont

      Our biotope with a content of approx. 1.5 m³ has existed for approx. 13 years. Every year a dense carpet of algae formed that could not be removed despite repeated water changes. After the water revitalization was installed in our single-family home at the beginning of May 2012, the biotope was filled with revitalized water for the first time after basic cleaning. Despite a very hot summer and a lack of shade, fortunately there was no algae carpet and the water bubbled crystal clear.
