calculator for maintaining water quality in biofloc tanks

During the starting of the culture period, high carbon-to-nitrogen ratio (12–20:1) in water is a key factor to promote and stabilize the heterotrophic community in Biofloc Technology. The following calculator can be used to calculate the amount of molasses need to bee added in the tank. 

For the maintenance phase, the monitoring of TAN values is an important tool for water quality maintenance. When values of TAN are higher than 1.0 mg per Litre, external carbon source application is recommended with a C:N ratio of 6:1. The molasses requirement in the tank during the maintenance phase can be calculated using the following calculator:
