By effectively eliminating bacteria, algae, chloramines and organic contaminants, it restores water clarity more rapidly and aggressively than regular sanitizers. Available in both chlorine-based options for heavy-duty sanitization and non-chlorine formulas for regular maintenance, Granular pool shock is a critical step in any pool-care routine.
