This finding is likely due to significant depletion of <br /> nutrients, especially nitrate and ammonium. While previous results indicated that microbial <br /> growth and metabolic activity could be achieved at lower than normal physicochemical values, <br /> it appears that the limiting level has been attained. Therefore, we recommend that additional <br /> supplementation be implemented utilizing ammonium nitrate to achieve approximately 25-50 ppm <br /> combined nitrate and ammonium levels within these waters. <br /> Should you have any questions concerning this information, please do not hesitate to contact me. <br /> I <br /> I <br />' AKK:ch <br /> I <br />
