SpaGuard pH Increaser for Spas & Hot Tubs, 3×18 oz Pack — Fast-Dissolving Granules, Protects Equipment

SpaGuard pH Increaser is a fast-dissolving granular treatment that raises low pH in spas and hot tubs to protect equipment and improve bather comfort.

Keeping spa water at the correct pH reduces corrosion, stabilizes sanitizer performance and eases irritation for bathers. This three-pack of 18 oz containers supplies a granular, slow-action pH-raising formula designed for accurate adjustments without sudden swings. Use it as part of a regular water maintenance routine to maintain balanced chemistry and protect plumbing, metal components and shell surfaces.

How quickly will this product change my spa's pH?

SpaGuard pH Increaser is formulated to dissolve quickly while gradually raising pH to give you predictable results. Because it raises pH slowly, you can test and adjust in small increments instead of overshooting the target.

• Dissolves rapidly for easy application.
• Intended for stepwise pH increases—test after each dose.
• Works in fresh and recirculating water systems.
• Suitable for standard residential spa volumes.

What equipment and problems does it help protect?

Low-pH water accelerates metal corrosion and can damage heaters, pumps, filters and jets. Raising pH to the recommended range helps reduce metal wear and prevents the acidic environment that contributes to surface etching and plumbing deterioration.

• Minimizes corrosion risk to heaters and metal fittings.
• Reduces accelerated sanitizer consumption caused by low pH.
• Helps prevent staining and surface damage from acidic water.
• Supports overall water balance when used with alkalinity controls.

How should I use SpaGuard pH Increaser safely and effectively?

Follow label directions and retest water after each application. Add the granules to circulating water, allow full dissolution, then measure pH before repeating. Avoid adding product directly to skimmer or near acrylic surfaces without dilution.

• Test pH and total alkalinity before dosing.
• Broadcast granules evenly into the spa while the pump is running.
• Wait and retest after 15–30 minutes; repeat as needed.
• Store containers tightly closed and out of reach of children.

How does this fit into regular spa maintenance?

Balanced pH is one component of a complete maintenance plan that also includes alkalinity control, sanitizer management and regular filter cleaning. Use SpaGuard pH Increaser when tests show pH is below the desired range to restore balance and stabilize other chemical levels.

• Use alongside alkalinity increasers/decreasers for fine-tuning.
• Combine with your usual sanitizer schedule for consistent protection.
• Regular testing prevents repeated large adjustments.
• Three 18 oz containers provide multiple treatment sessions.

Who is this for: SpaGuard pH Increaser is aimed at hot tub and spa owners, property managers and service technicians who need a dependable, easy-to-use pH raising product. It’s useful for anyone experiencing low-pH symptoms—such as eye irritation, strong chemical odors, or metal staining—or for those who want to protect heaters, pumps and fittings by keeping water chemistry within safe limits. For best results, use it as part of a routine water-care plan alongside test strips or a digital tester and appropriate alkalinity controls.
