Description
Stain, Scale and Rust Protection With Built-In Clarifying
Sirona™ Spa Care Protect Plus is a dual-purpose liquid concentrate that protects your hot tub against stains and scale by suspending stain-causing minerals, while a built-in flocculating agent clarifies the water to keep it sparkling clear.
Add it when you fill the spa and then weekly to protect your shell, jets and equipment. It's compatible with all sanitizers.
Stops Stains and Scale Before They Form
Fill water can carry iron, copper, manganese and calcium. Protect Plus suspends those stain-causing minerals in the water so they can't settle on your spa shell or build up as scale on jets and heater components.
Clarifies While It Protects
A built-in flocculating agent gathers fine particles so your filter can catch them, brightening dull water while the stain and scale protection works in the background.
Extra Protection for Well Water and High-Mineral Fills
If your fill water is high in metals or minerals, the start-up dose simply doubles to 4 fl oz per 250 gallons. That gives fresh water the extra protection it needs from day one.
Simple Weekly Maintenance
After the initial fill, just 1 fl oz per 250 gallons a week keeps protection in place. It's compatible with all sanitizers, so it fits any spa routine.
