Results for the various water physico-chemical parameters recorded for the AquaHerb treatment at three different point of observation are presented in Table 2. The results revealed that several parameters including nitrite, nitrate and posphate were affected by the addition of AquaHerb during the conditioning treatment. During conditioning, mean water pH of 24 h and 36 h was slightly higher than 12 h both on Seabass and Pompano rearing tank. This might be due to the impact of trace elements contained in AquaHerb that dissolved in the water. However, the range of pH still agreed with the range recorded by Sirajuddin (2009). In addition, the mean of nitrite, nitrate and posphate at 24 h and 36 h also showed an elevated concentration compared to 12 h of conditioning treatment both in Asian Seabass and Silver Pompano tank. This is mainly due to the influence of mangrove and neem extracts that contributed to the high inputs of nitrogen dissolved in the water. However, the value of nitrite, nitrate and phosphate are still within the accepted range (Sirajuddin, 2009) and also act as the “hospital for sick fish” just like mangrove ecosystem in marine environment.
