Quick start for the filter – AquaActiv BioKick are suitable for pond sizes up to 5 m³. In just a few days, your filter will be 100% functional and can achieve its full filtering effect. By colonising the filter sponges, the starter bacteria in the AquaActiv BioKick in the 95 g small container ensure that dirt or even nitrite, ammonium and ammonia are broken down. This effectively prevents sudden fish deaths caused by these harmful substances. The BioKick is recommended not only for a new filter, but also for re-use in spring, for partial water changes or after filter cleaning. AquaActiv OptiPond and AquaActiv Safe & Care are the ideal complement to this.
