For controlling bacterial and algae in hot tubs, spas and pools. These smaller chlorine tablets are designed for use with chlorine feeders or with floating dispensers.
They will slowly erode over a period of 3-5 days depending on the water flowing over them. As they release chlorine relatively slowly it may be necessary to shock dose or oxidise prior to their use, to first establish some chlorine more rapidly.
