Oxy Tab is a combination of sodium percarbonate and calcium peroxide which is used extensively for aqua culture throughout the world. Oxy Tab increases the level of dissolved oxygen (DO) and potentiates the water treatment. Dissolved oxygen is essential to meet the demand of oxygen in the pond especially in over loaded ponds. For respiration of the cultured aquatic animals (prawns/fish). For the growth of aerobic bacteria which decomposes the harmful organic load.
