Take it to a floating reservoir, which has a value of TK n. About 20-70 mg per litre of phosphorus and approximately 1-7 mg per liter. Analysis of phosphorus and nitrogen content was reduced in the form of a TK n (Kjeldahl Total Nitrogen: TKN) and phosphorus (Total Phosphorus: TP) including formaldehyde analysis (Chemical Oxygen Demand COD:) find that performance occurs. At various times, is 15, 30, 45 and 60 days to find the appropriate moment to nitrogen and phosphorus treatment by age range, growth is growth age range 1 – 6 months.
