SpaGuard Stain, Scale & Water Clarity

SpaGuard FAQs

Does SpaGuard make chlorine and bromine products for hot tubs?

Yes. The SpaGuard collection includes chlorinating concentrates, brominating concentrates, bromine tablets, and rapid-dissolve chlorinating tabs, giving you products for different hot tub sanitation routines.

What SpaGuard products help with pH and alkalinity?

SpaGuard pH Increaser and pH Decreaser adjust pH, Total Alkalinity Increaser raises low alkalinity, and Rapid-Dissolve pH Decreaser and Alkalinity Increaser Tabs offer pre-measured doses. Spa Sentry helps hold pH in range between adjustments.

What can I use when my hot tub has stain, scale, or water-clarity issues?

For metal stains and scale, use SpaGuard Stain and Scale Control or Rapid-Dissolve Stain and Scale Control. For dull or cloudy water, Water Clarifier gathers fine particles so the filter can catch them. Phosphate Remover, Water Freshener, and Spa Complete target other specific water-quality concerns.

Does SpaGuard have products for filter, spa plumbing and system maintenance?

Yes. SpaGuard Filter Cleaner is available for filter maintenance, while SpaGuard System Flush is intended for spa-system care. These products cover maintenance beyond treating the water itself.
