Bottom Line
Clorox Pool and Spa Shock Plus, 1 lb is a solid choice for pool maintenance, especially if you want an affordable solution that can effectively kill algae in non-circulating pools. However, it may not be the best option for vinyl pools due to potential bleaching issues. Despite its slower action compared to traditional chlorine shock products, it eventually provides good results if used properly. For those seeking quicker and more effortless algae removal, a Calcium Hypochlorite product might be a better alternative.
