Ponder is designed for surface water conditions found in farm ponds and storm water reservoirs, ornamental ponds, golf course ponds, municipal reservoirs and lakes. Ponder assists in the breakdown of organic matter by stimulating the various resident microbial communities present in water bodies. Stimulation of these microbial communities acts to balance microbial populations, resulting in the digestion of organic solids at optimum rates and thus reducing offensive odors and discoloration of water. Please note that Ponder is not an algaecide and should not be used in conjunction with chemicals. The raw materials used to manufacture all SHAC products are acquired from one of the highest quality humate sources in the world.
