FROG Maintain for Swim Spas - Non-Chlorine Shock Monthly Treatment

In this review of FROG Maintain for Swim Spas the bottom line is simple: this is a convenient, non-chlorine monthly shock designed for owners who already use the FROG @ease Floating System and want an easy way to keep swim spa water clear. The reviewer found the single-dose packets simple to use, fast-dissolving, and effective at removing organic contaminants without adding chlorine. For swim spa owners managing up to 3,000 gallons who prefer a monopersulfate shock compatible with most chemical programs, this product is worth considering.

Key Features

• Non-Chlorine Shock: Provides a monthly monopersulfate shock that refreshes water without adding chlorine, which helps maintain a milder water feel.
• Single Dose Packets: Prefilled packets make treatment straightforward - cut and pour for a consistent dose that dissolves quickly.
• Works with FROG @ease: Specifically recommended to pair with the FROG @ease Sanitizing System and extends SmartChlor cartridge effectiveness.
• Capacity Certified: Each packet treats swim spas up to 3,000 gallons, covering typical home swim spa volumes.
• Chemical Compatibility: Monopersulfate formulation is compatible with most swim spa chemicals and water care programs except biguanides.
• Reduces Organics: Designed to eliminate organic contaminants that can cloud water and shorten sanitizer life.

Who It's For

FROG Maintain is best for swim spa owners who already use or plan to use the FROG @ease Floating System and want a low-effort monthly maintenance step that supports the SmartChlor cartridge. It suits people who prefer a non-chlorine shock option and need a clear, premeasured treatment for up to 3,000 gallons.

It is less useful for owners relying on biguanide-based programs, or for those who need daily sanitizing solutions rather than a monthly shock. If you have a very large commercial spa over 3,000 gallons, you will need a different dose or product.
