Description
Pool&Spa XtraBlue Pool Shock is a fast-dissolving pool and spa shock treatment designed to quickly clear cloudy water and keep swimming areas healthy. Homeowners reach for it to kill and prevent algae with its algae-fighting formula while also eliminating bacteria, so pools stay clearer and more inviting. Because it dissolves rapidly and makes water swim-ready in about 15 minutes, it’s ideal for weekend backyard gatherings, post-storm cleanups, or regular weekly maintenance. The blue solution helps you see treatment in the water as it disperses, and its formula supports improved filter performance by breaking down contaminants that can clog equipment. Made in the USA and offered in a 1-pound size, XtraBlue is a straightforward shock option for routine sanitizing and quick-turnaround pool care.
