FROG Maintain Non-Chlorine Hot Tub Shock Packets — 6 Single-Dose Packets, Premeasured Monopersulfate for Clear Water

FROG Maintain for Hot Tubs is a prefilled, non-chlorine shock in single-dose packets designed to eliminate organic contaminants and restore clear, balanced hot tub water.

Keeping hot tub water fresh between routine sanitizer doses is easier with a non-chlorine oxidizer that dissolves quickly and won’t require measuring. FROG Maintain is a monopersulfate-based shock that pairs with all FROG hot tub sanitizing systems; each single-use packet treats up to 600 gallons and simplifies maintenance while helping maintain sparkling, comfortable water.

How does FROG Maintain work with my existing FROG sanitizing system?

FROG Maintain complements FROG mineral and bromine systems by oxidizing organic contaminants that build up during regular use. It refreshes water clarity and helps your sanitizer work more effectively without introducing chlorine.

• Formulated as monopersulfate for safe oxidation
• Compatible with FROG @ease and FROG Serene systems (see frequency below)
• Does not interfere with mineral cartridges or prefilled sanitizer delivery

How often should I add FROG Maintain to my hot tub?

Frequency depends on which FROG system you’re using and how often the tub is used. For FROG @ease, one packet monthly is typical; for higher-use tubs or FROG Serene systems, weekly additions ensure consistent water quality.

• FROG @ease: add once a month
• FROG Serene: add once a week
• Increase frequency with heavy bather load or after parties

How do I use a single-dose FROG Maintain packet safely?

Each packet is premeasured for simplicity and safety—no measuring spoon required. Cut the packet open and pour contents directly into the hot tub with the circulation system running; it dissolves quickly and disperses evenly.

• Treats up to 600 gallons per packet
• Cut open packet and pour in with jets on
• No direct handling of loose chemicals needed

Is FROG Maintain compatible with other hot tub chemicals?

FROG Maintain is compatible with most hot tub water care products, except biguanide-based systems. It can be used alongside chlorinated, brominated, and mineral programs to maintain clarity and reduce organic load.

• Works with chlorine and bromine programs
• Safe with FROG mineral technology and cartridges
• Avoid mixing with biguanide (PHMB) systems

Who this is for: FROG Maintain is made for hot tub owners who want a simple, premeasured oxidizer that reduces organic contaminants without adding chlorine, and for anyone using FROG sanitizing systems who prefers predictable, low-fuss maintenance. It’s especially helpful for households that want fast dissolving packets, minimal chemical handling, and clear water between regular sanitizer treatments.
