Support answer · pH

Can pH Plus be used the same way in pools and spas?

Short answer: pH Plus raises pH in both pools and spas, but dosing and circulation times differ.

Based on Maytronics support, updated 2026-07-21, rewritten by Poolbots' pool experts.

The answer

What to know.

Not exactly. pH Plus (pH Up) raises pH in both pools and spas, but the water volume affects how you apply it.

  • Pools: The larger water volume calls for careful dosing and a longer circulation period of 2-4 hours.
  • Spas: The smaller water volume and jets help disperse the chemical faster, with a shorter circulation period of 15-30 minutes.

Follow the product's directions for pool or spa use. Using the correct dose helps prevent adding too much and raising the pH too high.
