Why customers choose PatioZora Garden

Balanced Water, Clearer Surfaces, Easier Maintenance

FROG DropH pH and Total Alkalinity Down is a fast-dissolving solution designed for hot tubs and swim spas. In one 3-lb bottle with the TruDose measuring cap, it helps bring pH and total alkalinity into a friendly range, typically around 7.2 to 7.8. When water sits at this balance, you may notice clearer surfaces, better sanitizer effectiveness, and a more comfortable soak. This product is sold as a two-pack for ongoing maintenance.

How it works

DropH is formulated to dissolve quickly, and the TruDose cap seals the bottle to prevent leaks. The translucent cap makes dosing intuitive, using standard cup and tablespoon indicators. You won’t need to do extensive math—just follow the simple instructions and use any standard test strip to verify numbers.

Key benefits you may experience

  • Precise dosing with the integral TruDose cap for fewer dosing guesses
  • Compatibility with chlorine, bromine, or salt systems across any tub size
  • Clear instructions and measurement cues designed for hot tubs and swim spas
  • Improved water appearance and feel thanks to balanced pH and alkalinity
  • Potentially more effective sanitization due to stable pH in the right range

Why choose FROG

With more than 25 years of water-care expertise, FROG blends Mineral Technology with prefilled cartridges to help deliver cleaner, softer water. The DropH line is built for ease of use and consistent results over time.

Usage tips

Follow the dosage guide for hot tubs or swim spas, then re-test and adjust as needed. Store the kit away from direct sun, and keep the TruDose cap closed between uses.
