FROG StoMPS is a non-chlorine oxidizing shock that quickly removes organic contaminants and refreshes hot tub and swim spa water without adding chlorine.

Maintain clearer, fresher water between regular sanitizer treatments with a fast-dissolving, chlorine-free oxidizer designed for hot tubs and swim spas.

The 2 lb bottle includes the TruDose measuring cap for reliable, spill-free dosing and simplified maintenance.

How does StoMPS improve water clarity and reduce odor?

StoMPS works by oxidizing bather wastes, oils and other organic debris that make water cloudy and smelly. It doesn’t sanitize, but it removes the materials that consume sanitizers and create unpleasant odors, helping your regular sanitizer last longer between doses.

• Non-chlorine oxidizer targets organic contaminants without adding free chlorine smell.
• Fast-dissolving formula mixes quickly for prompt impact after application.
• Supports clearer, brighter water by reducing solids that cause cloudiness.
• Compatible with chlorine, bromine and salt systems to complement any sanitizer.

How easy is dosing with the FROG TruDose cap?

The TruDose cap is translucent and marked with standard cup and tablespoon measures, making accurate dosing intuitive. It seals tightly to prevent spills and doubles as the measuring cup so you never need extra tools or guesswork when treating your tub or spa.

• Translucent cap shows precise cup and tablespoon indicators.
• Tight seal keeps powder contained during storage and transport.
• Use the cap to measure directly—no separate scoop required.
• Clear instructions on the label match common hot tub and swim spa sizes.

Will StoMPS work with my hot tub’s sanitizer or salt system?

Yes—StoMPS is compatible with all common hot tub and swim spa sanitizers including chlorine, bromine and salt systems. It’s formulated to oxidize contaminants without interfering with your existing sanitizer routine when used according to the dosing guide.

• Safe for chlorine, bromine and saltwater sanitizing chemistries.
• Label includes dosage guidance for both hot tubs and larger swim spas.
• Pairs with test strips or FROG testing methods for accurate water care.
• Helps maintain sanitizer efficiency by removing contaminant load.

How should I use StoMPS for best results?

Test water first with a standard strip or FROG test. With the pump running, add the measured dose of StoMPS using the TruDose cap, then allow the system to circulate for at least 15–30 minutes; repeat according to use and label directions.

• Always test water chemistry before treating.
• Add product with the pump or jets running for even distribution.
• Follow the bottle’s dosing table for hot tub and swim spa sizes.
• Use regularly after heavy use or when you notice cloudiness or odor.
