Helps establish a pond's biological filter. Aids in the elimination of toxic ammonia and nitrites. Restores and maintains a biological balance all season long. Contains 500 million live bacteria per ounce.
New ponds have no active biological filtration.
When fish are added to the pond, they immediately begin releasing toxic ammonia as a waste product. As uneaten fish food decomposes, it also releases ammonia and increases the level of dissolved organic compounds in the water. Such conditions result in high levels of toxic ammonia and nitrites, as well as low dissolved oxygen levels, all of which can lead to the outbreak of disease. The development of the biological filter is actually inhibited by these conditions, prolonging the stress on aquatic life. Pond Care Stress Zyme is a highly concentrated solution of bacteria that have been specifically selected for the development of biological filters in ornamental fish ponds.
