CLOROX Pool&Spa Pool Shock XTRABLUE Plus 6-Pack — Fast-Dissolving, Swim-Ready in 15 Minutes

Clorox Pool&Spa Shock XTRABLUE Plus is a fast-dissolving pool shock that kills bacteria and algae so your pool is safe to swim in as soon as 15 minutes after treatment.

Keep your pool clear and inviting with a multi-action shock treatment formulated to eliminate contaminants and inhibit algae growth. This 6-pack of powdered shock dissolves quickly, helps restore filter performance, and is labeled safe for all common pool surfaces including vinyl, plaster, fiberglass, and tile. Use regularly or after heavy use, storms, or hot weather to maintain balanced, crystal water.

How quickly will the pool be safe to use after adding this shock?

The XTRABLUE Plus formula is designed for rapid dissolution and quick sanitizing action so most pools can be ready to swim in about 15 minutes. Time to swim-ready may vary with water temperature, sanitizer levels, and circulation efficiency.

• Typical swim-ready window: approximately 15 minutes under recommended conditions.
• Ensure pump and filter run during treatment for best dispersion.
• Adjust timing for unusually cold water or very large pools.

What does the 6-in-1 formula do for pool water quality?

The product combines multiple actions to combat visible and invisible problems: it kills bacteria, tackles algae, helps clear cloudy water, and reduces contaminants that burden filters. By addressing several issues at once, it streamlines routine maintenance and restores clarity faster than single-action treatments.

• Kills bacteria and reduces organic contaminants that cloud water.
• Prevents and treats common types of pool algae for cleaner surfaces.
• Supports better filter performance by breaking down debris and dulling particles.

How should I dose and apply this shock to my pool?

Follow the label: use 1 pound of product per 12,000 gallons of pool water for standard shock treatments. Shock weekly as part of routine care and any time the pool experiences heavy swimmer load, hot weather, or rainfall that can introduce contaminants.

• Measure water volume and calculate pounds needed (1 lb per 12,000 gallons).
• Dissolve or broadcast product according to manufacturer instructions and run filtration during treatment.
• Retest water and chemical levels after treatment; follow any additional safety directions on the label.

Is XTRABLUE Plus safe for my pool surface and equipment?

This shock is formulated to be compatible with vinyl, plaster, fiberglass, and tile pool surfaces while delivering effective sanitation. As with any chemical, avoid overuse and follow dosing guidance to protect equipment, liners, and pool finishes.

• Label indicates compatibility with all common pool surfaces.
• Run pump and filter to distribute product and prevent localized concentration.
• Store unopened in a cool, dry place away from other chemicals.

Who is this product for? Pool owners and caretakers who want a fast, reliable shock treatment that handles bacteria and algae while restoring water clarity will find this 6-pack convenient and cost-effective. It's well suited for weekly maintenance, post-party or storm clean-up, and pool operators who prefer quick turnaround times. Use it when you want a rapid, multi-action sanitizer compatible with standard pool materials and systems; follow label instructions and local chemical handling guidance for safe use.
