LEISURE TIME Spa Down pH & Alkalinity Reducer — 2 x 2.5 lb Granular Hot Tub Formula, Fast-Dissolving

LEISURE TIME Spa Down is a fast-dissolving granular pH and alkalinity reducer designed to bring hot tub water back into the ideal 7.2–7.8 range.

Keeping spa water balanced maintains comfort, protects equipment, and helps sanitizers perform as intended. This two-pack of 2.5-pound containers provides a convenient supply of pH decreaser formulated specifically for hot water use. The granular formula dissolves readily, making it simple to lower both pH and total alkalinity when test strips or test kits show elevated readings.

How quickly will Spa Down change my hot tub's pH?

Spa Down is made to dissolve and start working soon after application, but the exact speed depends on water volume, current pH/alkalinity and circulation. Retest after circulating for 30–60 minutes and adjust gradually to avoid overshooting the target.

• Add small increments, then allow 30–60 minutes of circulation before retesting.
• Work in stages for large pH reductions to prevent sudden swings.
• Use alongside a reliable test kit or strips for accurate results.

Will this product work with my sanitizer and hot tub materials?

Yes — the formula is compatible with common sanitizers including chlorine, bromine and biguanide, and it’s designed for use in typical hot tub finishes and components. Follow manufacturer instructions for your specific spa model as a general precaution.

• Safe with bromine, chlorine and biguanide sanitizing systems.
• Formulated for hot water environments and common spa surfaces.
• Adjust pH without interfering with your existing sanitizer routine.

How do I use Spa Down safely and effectively?

Measure your spa’s pH and total alkalinity first, then add Spa Down in small amounts to the water while the pump is running. Always follow label directions, avoid adding product directly to the filter or shell, and wait to retest until the water has fully circulated.

• Test pH and alkalinity before treatment; target pH 7.2–7.8.
• Dissolve or broadcast granules while the pump circulates; do not add to the filter area.
• Retest after 30–60 minutes and repeat small doses if needed.

What results should I expect after balancing with Spa Down?

Balanced pH improves comfort, reduces scaling and cloudiness risks, and helps sanitizers work more efficiently. Keeping pH within the recommended range also prolongs the life of spa equipment and surfaces when maintained consistently.

• Less eye and skin irritation when pH is in range.
• Fewer scale deposits and clearer water appearance.
• Improved sanitizer performance at recommended levels.
