Ammonia has a high toxic effect for all living forms. When exposed to in low quantities, it can be tolareted by the living forms. Compared with clay minerals, bentonite has a high usability due to its high adsorption capacity and low cost. In this study, it was aimed to determine the effects of two different amount of bentonite on the ammonium adsorption in freshwater at 17±1°C. In this research two trial groups with 3 repetitions were created for two different bentonite rate. Experimental groups were prepared by adding 2 liter of water and NH4Cl to each bottle to give an NH4+ amount of 10 mg/l. After that, two amounts of bentonite (7 g/l, 14 g/l) were added to the bottles. Water temperature, pH, dissolved oxygen and TAN (Total Ammonium Nitrogen) values were determined during the trial period. At the end of trial NH3 values were calculated as 0.461±0.01 mg/l and 0.463±0.01 mg/l in different amount of bentonite groups (7 g/l, 14 g/l), respectively. There were difference in TAN values between the experimental groups (p<0.05). As a result in this study, it has been determined that the amount of 14 g/l bentonite is the ideal amount for ammonium removal in aquaculture.
