Detailed product description

Natural bacterial product for long-term clean garden pond or fishpond (for 15 m2).

The result of using Mr. Bacteria No. 3 is a clean garden pond or fishpond without cyanobacteria and cloudiness. Organic deposits decompose at the bottom and in the water column. This results in the removal of brown and cloudy water. The product contains highly mobile natural bacteria with positive chemotaxis. The bacteria can recognize the type of chemical waste and swim to it, because this waste is their food, thus they are keeping the water clean. During the action of the solution, there is a significant reduction of phosphorus and chlorophyll A in the garden pond and fishpond. Algae and cyanobacteria are eliminated by bacteria breaking down the substances that support the growth of algae and cyanobacteria. The pond or fishpond is consequently phosphate-free. Brown water, cloudy water and total cloudiness in the water column are removed. The oxygen content increases and the cyanobacteria are removed. With regular application of Mr. Bacteria No. 3 (pond, fishpond) bacteria are reproduced, which results in your constantly, long-term clean pond and fishpond.
