BioGuard Basic Shock (12 LB)

The BioGuard Basic Shock is a simple but highly effective pool shock. It does not have any extra additives that can dilute the potency of chlorine so your pool will be sanitized properly. Often times the enhancers built into chlorine shocks and tablets make the cost of the product to go up, but does not always treat the full issue. Using this shock will keep water healthy and give pool owners peace of mind that no money was wasted on the unnecessary additives.
