FROG StoMPS Non-Chlorine Shock Oxidizer for Hot Tubs and Swim Spas - 2 lb Bottle

Fast, Chlorine-Free Oxidizing Shock for Cleaner Spa Water

FROG StoMPS Non-Chlorine Shock Oxidizer helps keep hot tub and swim spa water clean, clear, and ready to enjoy by oxidizing contaminants like sweat, oils, and organic buildup. It gives your sanitizer a helpful boost without adding chlorine or cyanuric acid, making it a smart choice for routine hot tub maintenance, swim spa treatment, and FROG water care systems.

This 2 lb bottle includes the FROG TruDose Measuring Cap, which helps make shock dosing easier and more accurate. Simply pour FROG StoMPS into the cap, measure with the built-in markings, and dose according to the chart on the bottle. The cap seals tightly and helps reduce over-dosing or under-dosing, so regular spa maintenance feels simpler and more consistent.

Use FROG StoMPS as part of your ongoing water care routine, after heavy use, or whenever water needs an oxidizing refresh. For best results, balance total alkalinity, pH, and total hardness first, then use FROG StoMPS with the jets running while the hot tub or swim spa is not occupied.

Product Details

Compatibility and Requirements

FROG StoMPS is made for hot tubs and swim spas and is compatible with FROG sanitizing systems when used as directed. It can be used with any FROG hot tub or swim spa sanitizing system, or with your preferred sanitizer routine, after the water is properly balanced.

Before shocking, test and balance the water. FROG recommends maintaining total alkalinity at 80 to 120 ppm, pH at 7.2 to 7.6, and total hardness at 150 to 250 ppm. Once these levels are in range, add sanitizer according to your system instructions and use FROG StoMPS as part of your regular oxidizing routine.

For application, add FROG StoMPS with the jets running while the hot tub or swim spa is not occupied. Keep the cover off during circulation, allow the water to mix thoroughly, and follow the product label before re-entering.
