sera Pond Filter Booster

Activates the filter

  • contains highly concentrated purification bacteria for biological water conditioning
  • starts and improves the breakdown of pollutants such as ammonium or nitrite in the filter
  • bacteria decompose plant parts and fish waste
  • necessary at the start of the season and after cleaning the filter
  • for reactivating bacteria strains after medication


In a healthy filter cycle, living purification bacteria break down organic matter such as fish waste, dead algae or plant parts. When temperatures rise in spring, an insufficient amount of active purification bacteria can quickly lead to a problem and cause massive damage to the fish in the pond. It is particularly important to reactivate the nitrogen cycle quickly in case of new filter systems, restarting the filter, cleaning or replacing the filter media and also after using medication in the pond. Since useful filter bacteria multiply slowly and need time to form active strains, it is important to accelerate this activation process. This is the case for all filter types, whether pressure filters, flow-through filters or regeneration zones in natural ponds.

Pond Filter Booster adds highly concentrated purification bacteria directly onto the filter media to start the biological water conditioning process and activate it as quickly as possible. Many colonies of different bacteria strains break down pollutants such as ammonium or nitrite in the filter. Fish waste and other organic matter are decomposed. Pond Filter Booster is also ideal during the pond season, for example in case of changes in fish stock or after cleaning the filter, to support existing and weakened bacteria and create a smooth transition phase.


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.
