After combating algae the decaying algae release free nutrients. These free nutrients can become the basis for new algae to grow, often even faster than before. Therefore it is imperative to bind these free nutrients after the algae treatment. OASE WATER TECHNOLOGY offers some of the world's best nutrient binders. The nutrients are bonded in a way that means they can not be used by algae as a food source. They are able to act as a food source for desired water plants.
