Composition and method for treating fluids with select facultative organisms and/or nutrients. At least one facultative organism is selected and added to a ,fluid, to stimulate/facilitate biological remediation of the ,fluid,. In one embodiment, the select facultative organisms are put into frac pits/ponds containing frac water to inhibit the sulfate reducing bacteria in the frac water.
