The document compares water quality test results from a pond before and after treatment with Nualgi. Key findings include large decreases in turbidity, suspended solids, nutrients, COD, BOD, and microorganisms. Turbidity decreased from 336.6 NTU to 3.78 NTU. Total suspended solids decreased from 154 mg/L to 14 mg/L. Total Kjeldahl nitrogen decreased from 18.76 mg/L to 0.28 mg/L. COD decreased 96% and BOD decreased 97% after 4 weeks of treatment. Total coliform decreased 99.95% and faecal coliform decreased 99.9%. Phytoplankton counts also significantly decreased.
