Why customers choose Cera Garden

Balanced hot tub water for a more enjoyable soak

When spa water climbs above the ideal pH range, you may notice a dull sparkle, reduced sanitizer effectiveness, and mineral buildup on surfaces. MAV AquaDoc Spa pH Decreaser is a liquid formula designed to gently lower elevated pH in hot tubs, helping you move back toward a comfortable, inviting soak with clarity in the water.

Key benefits at a glance

  • Two-bottle value: This 2-pack helps bring high pH down toward the 7.2–7.8 range, supporting a more inviting, balanced spa experience.
  • Balanced chemistry: Formulated with sodium bisulfate to nudge pH into the target range, aiming for clearer water and steadier sanitizer performance.
  • Sanitizer compatibility: By maintaining pH within range, sanitizers like chlorine or bromine can work more consistently without changing their levels.
  • Easy-pour liquid: The liquid formula blends smoothly into circulating water for even distribution and quick results, with simple dosing and prompt circulation before retesting.
  • Quality you can trust: Made in the USA by AquaDoc, reflecting consistent quality standards for hot tub care.

How to use

  1. Test your spa water to determine if pH is above the recommended range.
  2. With the jets running, pour the directed amount into the circulating water.
  3. Allow the system to circulate, then re-test and adjust as needed.
