Starter cultures are important for the biological maintenance of filters and pond water. Our BioKick starter cultures revitalise your pond and filters biologically. Also suitable for acute water problems. In combination with nutrient solution, the cultures are particularly suitable for waters with a light fish population. For heavily polluted filter systems, we recommend the premium version with a particularly high bacterial density. In this case, the filters regain their full capacity after just a few days. Cultures of this quality can be kept for years without refrigeration.
