With our pond cleaning services, we are able to effectively clean ponds and lakes with little or no use of aquatic herbicides. We are able in some circumstances to clean more than 99% of the weeds in an small amount of time, and providing very fast results. . The advantages of this method versus just herbicides is we remove nutrients stored in the plants we harvest. If you kill all the weeds they will sink and those nutrients will be recycled by more of the same weeds, other weeds or algae.
