Leisure Time Renew Granular Spa Shock 2.2 lb (4-Pack) — Fast-Dissolving Non-Chlorine Oxidizer for Clear Water

Leisure Time Renew Granular is a fast-dissolving, non-chlorine spa shock that clarifies water by removing oils, soaps and organic buildup in minutes.

If your hot tub or spa is cloudy, has surface films, or holds lingering residues from lotions and fragrances, Renew Granular offers a non-chlorine oxidizer that works quickly and is compatible with a range of sanitizing systems. Formulated with potassium peroxymonosulfate as the active ingredient, this granular shock helps break down organics that cause cloudiness and irritation without the strong smell or residual chlorine levels associated with traditional shocks. Because it dissolves rapidly, downtime is short and your spa can be back in use within minutes when directions are followed.

How fast will spa water clear after using Renew Granular?

Renew Granular dissolves quickly and begins oxidizing contaminants immediately, so you can expect visible improvement in clarity within minutes to a few hours depending on contamination level. For typical maintenance doses, the product works almost instantly and allows for minimal downtime.

• Dissolves rapidly for immediate oxidation action
• Clarifies cloudy water by breaking up oils and organic films
• Short return-to-use time—follow label directions for precise wait times

Is this compatible with my sanitizing system—chlorine, bromine or minerals?

Yes. Renew Granular is designed to be used with chlorine, bromine, ozone, and mineral sanitizer systems as part of the Reserve & Renew Chlorine-Free Sanitizing System. It oxidizes organic contaminants without interfering with your existing sanitizer when used as directed.

• Safe for use with chlorine and bromine systems when label directions are followed
• Works with ozone and mineral systems to boost oxidation of organics
• Suitable for both freshwater and saltwater pools, hot tubs, and spas

Will Renew Granular irritate skin or eyes like chlorine shocks?

Renew Granular is a non-chlorine oxidizer formulated to reduce the materials that often cause skin and eye discomfort—such as soaps, deodorants, and oils. While it is gentler than many chlorine shocks, you should still follow dosing and handling instructions to avoid irritation.

• Targets residue that contributes to skin and eye irritation
• Clarifies water without adding chlorine odor or residuals
• Always measure and dilute per label to ensure safe use

How do I dose and apply Renew Granular safely?

Measure the recommended amount based on your spa volume, dissolve the product according to label instructions, and circulate the water to distribute treatment evenly. Avoid adding the granular directly into the skimmer or onto hot surfaces—pre-dissolving or broadcasting while the pump runs helps ensure quick, safe action.

• Follow label dosing for your spa or hot tub volume
• Dissolve and circulate—do not add concentrated product to the skimmer
• Observe recommended wait times before re-entering the water

Who is this for? Leisure Time Renew Granular is ideal for spa and hot tub owners who want a fast-acting, chlorine-free option to remove oils, lotions and organic buildup—especially those using chlorine, bromine, ozone or mineral sanitizer systems who need rapid clarification with minimal downtime. It’s also a good choice for users seeking a gentler oxidizer to reduce surface films and improve water appearance without the strong chlorine odor.
