Why customers choose Cera Garden

Why balanced pH matters in your spa

SpaPure pH Up is a high‑quality pH balancer designed for spa and hot tub water. When pH drifts downward, water can feel harsher on the skin and may become more corrosive to metal surfaces and seals. Keeping pH within a comfortable range supports a calmer feel and helps protect spa components over time.

When pH is too low, sanitizers may work less efficiently and the overall water experience can seem less pleasant. A measured pH boost with SpaPure pH Up can help maintain water that feels smoother to the touch and easier on spa equipment, motivating you to enjoy your soak without worry.

Key benefits at a glance

  • Safely raises pH to maintain comfortable, balanced water.
  • Helps minimize corrosion risk and supports compatible operation with your sanitizer system.
  • Works with chlorine, bromine, silver-mineral, and ozone-treated spas.
  • Simple dosing and direct-to-water application.

Why choose SpaPure pH Up

  • Compatible with common spa sanitizers (chlorine, bromine) and alternative systems.
  • Direct addition to spa water—no pre-dissolving required.
  • 100% sodium carbonate formulation with clear sizing (16 oz bottle).

How to use SpaPure pH Up

  1. Turn on your spa circulation system.
  2. With pH between 6.8 and 7.1, add 1 oz per 500 gallons of water.
  3. If the pH is below 6.8, use 2 oz per 500 gallons.
  4. Circulate 15–30 minutes, then test pH again.
  5. If pH remains below 7.2, repeat the dosing steps until you reach 7.2–7.6.
  6. If you adjust pH frequently, test total alkalinity and adjust as needed.
  7. Note: SpaPure Simply Soft can help maintain a stable pH range and support buffering of alkalinity.
