The OASE DuoBoost was specifically developed to support the pond's biology. It consists of two coordinated phases:

• First active phase: A gel that is applied directly to the pond or the filter chamber. It contains an extremely active enzyme and bacterial liquid that breaks down organic dirt, ammonia, and nitrites while simultaneously activating the filter's biology.
• Second active phase: A ball with a diameter of 5 cm, which dissolves after a certain period and releases significant trace elements, co-substrates, metals, and valuable additives that would be difficult to introduce into an artificial pond.

The DuoBoost treatment can be repeated several times a year if necessary. Both phases form the basis for clear and healthy water as well as excellent pond biology. To clear green water, it is recommended to use a UVC device to help combat algae.
