sera Pond Water Stabilizer

Stabilizes water parameters



  • stabilizes the pH value and prevents suddenly sinking pH levels in the pond
  • increases the carbonate hardness gently and safely
  • ideal for the start of the season after the winter or with the first filling
  • for regular use, especially in case of high fish density and after heavy rainfall
  • creates optimal conditions for fish and plants


A stable pH value in a natural pond, fish pond or Koi pond is essential for a functioning ecosystem. External influences, such as heavy rainfall or soft original water (low carbonate hardness), but also a high number of fish and plants influence the water parameters and destabilize the pH value. This can result in suddenly sinking pH levels, threatening the lives of pond inhabitants. The early indicator for a destabilization of the pH value is the carbonate hardness. Water hardness above 5°dKH is considered to be the lower limit for sufficient buffering, which reliably prevents excessive pH variations.

Pond Water Stabilizer increases the carbonate hardness, stabilizes the pH value and thus creates a safe habitat for goldfish or Koi. In addition, Pond Water Stabilizer contains essential minerals and fills supply gaps when used regularly. This prevents the stress of the animals and creates optimal conditions for a long and healthy life. Sensitivity against diseases such as the well-known white spot disease, bacterial diseases and other parasites can be significantly reduced.


Optimal pond care for a healthy ecosystem

The garden pond is a sensitive biological ecosystem that is exposed to a wide variety of factors. Natural water evaporation, rain showers, but also significant temperature variations have an enormous influence on the biological equilibrium. The well-being of the animals in the pond, such as goldfish, Koi and native species, e.g. bitterlings and rudd, also depends on these factors. To stabilize the pond ecosystem, it is important to know the water parameters. Particularly in Koi ponds with high fish stock density, the pH value, carbonate hardness, total hardness, nitrite, nitrate and phosphate should be checked regularly using water tests (drop tests or strip tests). With the water conditioners, care products and filter media from sera, you can create an ideal basis and react quickly and easily in severe cases.
