Abstract: Pond ecology must be stabilizing so that a dynamic equilibrium is maintained. Often, this equilibrium is a resultant of specific quantities of organic & inorganic elements. But whenever these quantities increase abruptly, the ecology of the ponds goes off balance, usually leading to collapse of a near to ideal ecosystem. Through necessary, nitrates if in excess quantity, has adverse affects on the pond water ecology. Excessive of nitrates in a pond usually denotes contamination by anthropological activities. To maintain water health, it is necessary to understand the effects of these inorganic elements.
