A shape for chlorination and dechlorination tablets which reduces pillaring and wicking effects during fluid treatment and offers a consistent dissolution rate during the chlorination or dechlorination process. The opposing surfaces of the stacked tablets are formed by a combination of concave and convex shapes. The shape of the opposing surfaces prevents the formation of a central pillar, resulting in the formation of a side pillar instead. During the formation of the side pillar, the fluid contact surface area of the tablets gradually increases to compensate for the diminishing periphery of the tablets. As a result, the dissolution rate of the tablet is kept substantially constant over the course of tablet dissolution. The shape of the opposing surfaces of the stacked tablets also only provides for minimum contact between adjacent tablets, slowing the moisture diffusion speed and minimizing wicking effects.
