Pond & Biotope

Clear water in bathing and fish ponds

Clear water in bathing and fish ponds is essential for maintaining healthy ecosystems. Natural ponds and biotopes are delicate ecosystems that rely heavily on the stability of their microbiology. When the biological water cycle is disrupted, the balance shifts, leading to issues like green, murky water and excessive algae growth. During the summer months, the increasing number of hot days poses new challenges for pond owners.

GRANDER® technology can intervene precisely at this point, enhancing the self-cleaning process and strengthening the biological balance. The plants around the pond also benefit from GRANDER® revitalized water, becoming more resilient to environmental influences and growing faster.

Users from both domestic and international contexts report that the revitalized water improves the health of fish and other organisms in the biotope. Often, muddy, algae-covered bottoms clear up with GRANDER® water revitalization, resulting in crystal-clear water.
