The feasibility of using two fertilizers (urea plus superphosphate) in tap water as a medium for the mass culture of green algae ( Scenedesmus and Ankistrodesmus ) in outdoor plastic‐enclosed minipond systems was investigated. Experiments in which the basic fertilizer‐tap water medium was enriched with micro‐ and/or macronutrients revealed no nutrient deficiency symptoms in the algal biomass produced. Biomass production was found to be quantitatively related to the concentration of fertilizer added and maximal production (> 15 g/m 2 day) was achieved following the addition of 30 mg N/L (1.89 g N/m 2 day) and 4.5 mg P/L (0.28 g P/m 2 /day).
