Our proprietary powder pond bacteria formulation contains a blend of beneficial pond bacteria that can perform in water temperatures as high as 110 F, and as low as 35 F. WE package our pond bacteria powder into pre-measured water-soluble packets, to make application simple. Just toss packets directly into the pond, and they start to dissolve within minutes. Our pond bacteria formulations have been proven for over 25 years, to naturally eliminate murky water, bottom-sludge (muck), excess fish food, fish wastes, problem nutrients (such as nitrate and phosphate), toxins (such as ammonia and nitrite) and odors. Our natural pond bacteria treatment reduces the need for harsh chemicals, to maintain ponds and lakes
