Oase AquaActiv DuoBoost - 250ml/5cm

AquaActiv DuoBoost is the two-phase booster for a healthy pond biology. The first phase of action consists of a highly active fluid gel containing enzymes and bacteria that remove organic dirt, ammonium, nitrite and nitrate. This also activates the filter bacteria. The second phase of action is balls measuring 2 cm, or a single ball of 5 cm diameter. These dissolve over time, releasing important trace elements, co-substrates, minerals and valuable additives that are otherwise difficult to put into an artificial pond.
