Mineralization and nitrification processes were monitored during the conditioning period of replicate recirculating seawater systems A and B. High-quality water was achieved by a combination of bacteriological and mechanical filtration, activated charcoal adsorption, foam separation and uv sterilization. These two systems were conditioned over a 12-week period using penaeus merguiensis as conditioning animals. Detritus from fecal matter and food increased ammonia levels immediately. At two weeks, nitrite levels increased and ammonia fell. Nitrite levels remained high until week 8 in system A and week 10 in system B. (Copyright (c) CSIRO Australia 1986.
