DuoBoost 5 cm 250 ml

The DuoBoost oasis was specially developed to support pond biology. It consists of two coordinated working phases:
The first active phase is a gel which is administered directly into the pond or the filter chamber. It consists of a highly active enzyme and bacterial liquid, which breaks down organic dirt, ammonium and nitrite and at the same time activates the filter biology.
The second active phase consists of a ball with a diameter of 2cm, which dissolves after a while and thus releases important trace elements, cosubstrates, minerals and valuable additives that would otherwise be difficult to get into an artificial pond.

You can repeat the treatment with DuoBoost several times a year if necessary. Both phases form the basis for clear and healthy water as well as excellent pond biology. For the clarification of green water, you should use a UVC clarifier to help combat algae.
