DuoBoost - 2-phase-booster for a healthy pond biology.

For garden lovers who want to keep their pond water clear the natural way: The innovative bacteria gel and optimally chosen minerals work in a double action to activate the natural pond biology of the water in a quick and easy process. 


  • BASIS FOR CLEAR WATER: Positively influences pond biology
  • SIMPLE: Place the gel or ball directly in the filter or pond – if the pond contains fish, place the balls in the enclosed net
  • FOR ALL POND TYPES: Important trace elements and minerals for all kinds of pond
  • TWO-PHASE EFFECT: Use in two phases:

Phase 1: Highly active bacteria gel
  • Fluid containing enzymes and bacteria
  • Effectively reduces nitrogen compounds and promotes the degradation of organic pollutants, ammonium, nitrites and nitrates
  • Activates filter bacteria

Phase 2: Effective mineral ball

  • Contains important trace elements, co-substrates, minerals and valuable additives that are hard to come by naturally in artificial ponds
  • The ball completely dissolves over time


Apply DuoBoost quickly and easily:

The gel and balls can either be placed straight into the pond or added to the filter chamber. AquaActivDuoBoost can be used several times a year depending on requirements.

If the pond contains fish, the mineral ball(s) can simply be put into the supplied net, and the net can either be placed at the edge of the pond or into the filter chamber to ensure the safety of the fish.
