Leisure Time RENU5 Renew Non-Chlorine Shock - Clear Spa Water Fast

In this review of Leisure Time RENU5 Renew Non-Chlorine Shock, the bottom line is simple: this 5-pound tub is for hot tub and spa owners who want a reliable weekly oxidizer to clear cloudy water and remove odors without adding chlorine. The reviewer found it effective at breaking down oils, soaps and sweat, and liked that it is compatible with chlorine, bromine, ozone and mineral systems. For anyone who prefers a non-chlorine maintenance product that is buffered to protect pH, this treatment performs predictably and is easy to use when keeping a spa clean between deeper cleans.

Key Features

• Non-chlorine oxidizer: Clears cloudy water and eliminates odors and common contaminants without adding free chlorine to the spa.
• Broad system compatibility: Works with chlorine, bromine, ozone and mineral purification systems so it fits most existing spa setups.
• Buffered formula: Prevents pH fluctuations so weekly use does not destabilize water balance in the spa.
• Quick re-entry time: Spa can be used about 15 minutes after treatment, which is convenient for regular maintenance.
• Destroys organic buildup: Breaks down microorganisms, soaps, deodorants and oils that lead to cloudy water and odors.

Who It's For

Leisure Time RENU5 is best for homeowners with hot tubs or spas who perform routine weekly maintenance and want a non-chlorine option to keep water clear between major treatments. It suits people using mixed sanitation systems, including chlorine or bromine as primary sanitizers or those with ozone or mineral purifiers.

It is less appropriate for someone seeking a one-step shock that replaces sanitizers entirely; this product is an oxidizer meant to complement, not substitute, primary sanitizers. Also, buyers who require an instant knockout sanitizer after heavy bather load may prefer a chlorine-based shock instead.

Pros & Cons

Pros

• Compatible with multiple sanitation systems, making it versatile for different spa setups.

Cons

• As a non-chlorine oxidizer, it does not replace a sanitizer and must be used alongside a primary sanitizer.
