<![CDATA[Fish pond water is rich in micro and macro nutrients originated from feces and fish feed remains and it may be used to grow the microalgae such as Chlorella sp. A study to understand the growth of Chlorella sp in the pond water media and the amount of nutrient used was conducted from January – March 2016. The Chlorella sp. was grown indoor and outdoor. Parameters measured were Chlorella sp. biomass, nitrate and phosphate content. Samplings were conducted once/10 days. Results shown that Chlorella sp. grow well in the pond water. The biomass of indoor Chlorella sp. was higher than that of the outdoor (0.005 g/L and 0.003 g/L respectively). Nitrate and phosphate content was decreased during the experiment, the nitrate was reduced by 7.4 mg/L (indoor) and 9.4 mg/L (outdoor), while the phosphate was reduced by 0.09 mg/L (indoor) and 0.26 mg/L (outdoor). Based on data obtained that the waste can be used to grow microalgae Chlorella sp. Keywords: Fish pond water, Chlorella sp., indoor, outdoor]]>
