Not every pond owner uses a filter (unfortunately). But if there is already a filter in the pond you need to spend a little time maintaining it.
Filters not only have the aim of removing turbidity from the water but also of providing ideal colonisation conditions for bacteria which decompose pollutants. A new or a newly cleaned filter is clinically dead. Bacteria haven’t yet settled on the filter material and it needs several weeks before a filter has been completely colonised by bacteria. Therefore you need to give the bacteria a helping hand. JBL FilterStart Pond contains enough bacteria to activate your filter within a few days and therefore making it fully functional.
The use of JBL FilterStart Pond is not just recommended for initial startup , but also after the use of remedies, after disinfection measures or after the cleaning of the filter.
