The BFT system utilizing NaHCO3 and Ca(OH)2 demonstrates best results for final weight, specific growth rate and net yield. The amount of NaHCO3 and Ca(OH)2 used for pH maintenance relative to feed are 14.64 ± 0.49 and 7.18 ± 0.32%, respectively. The alkalizing compound utilized cause increased on Ca2+ and Na+ levels. The control of total solid suspension is the challenge for high density systems.
