The strong acidity of water and soil in areas containing sulfate is the issue in aquaculture. This research aimed to investigate the influence of each liming material with different dosages to minimise the acidity effects in soil with acid sulfate content and to enhance water alkalinity. Dolomite (Ca Mg(CO3)2); (DA)50, (DB)10, and (DC) 5 ton/Ha), hydrated lime (Ca(OH)2); (HA) 2300, (HB) 1500, and (HC) 1300 Kg/Ha, as well as burnt lime (CaO); (OA) 260, (OB) 210, and (OC) 150 Kg/Ha were applied. Results indicated that each liming material affected the increase of pH in the sediment and water, alkalinity, as well as the decomposition of organic carbon. The highest dosage used in dolomite (DA), hydrated lime (HA), and burnt lime (OA) resulted in the highest pH level for soil and water, as well as alkalinity. The lowest amount of organic carbon was also recorded. Further analysis showed a high concentration of total calcium and magnesium and a decrease of acid-forming cations. An enormous amount of dolomite was needed, unlike burnt lime and hydrated lime treatments, to achieve the desired alkalinity and pH for both soil and water. Consequently, higher expenditure will probably be incurred in the extensive use of dolomite. Nevertheless, based on the results of soil and water properties, the application of hydrated lime (HA) tend to be more reliable in terms of effectiveness to minimise the problem in acid sulfate area.
