Leisure Time Spa Up spa alkalinity increaser, 2 lb 2-Pack — concentrated granular, gradual action

Leisure Time Spa Up is a concentrated granular formula designed to raise and stabilize total alkalinity in hot tubs and spas for more comfortable, balanced water.

Keeping a spa's total alkalinity (TA) in the recommended range is essential to prevent pH swings and protect equipment and surfaces. Leisure Time Spa Up delivers an easy-to-measure, gradual alkalinity boost that works smoothly with chlorine, bromine, ozone, and biguanide sanitation systems. This 2-pound, two-pack supply is tailored for homeowners and service professionals who need reliable, predictable TA adjustments without overshooting targets.

How does Spa Up raise total alkalinity without causing pH bounce?

Spa Up uses a concentrated granular chemistry that dissolves steadily, allowing you to correct TA in controlled increments. Because it’s designed for gradual action, it reduces the risk of sudden pH shifts that can irritate swimmers or stress equipment. Follow dosing guidance and retest to achieve a stable range.

• Add small, measured amounts to increase TA gradually.
• Wait and retest after circulation to avoid overcorrection.
• Compatible with common sanitizer types to maintain overall balance.

How much should I use to bring my spa into the 80–120 ppm range?

Dosing depends on current TA, spa volume, and water chemistry, but Spa Up is formulated for predictable results when used incrementally. Start with conservative doses, then allow the water to circulate and retest before adding more. This stepwise approach helps you reach the 80–120 ppm target without overshooting.

• Test total alkalinity before any treatment.
• Add Spa Up in small portions, then circulate and retest.
• Adjust further only after confirming the new TA reading.

Will Spa Up work with my sanitizer system?

Yes—Spa Up was formulated to be compatible with a wide range of spa sanitizers, including chlorine, bromine, ozone, and biguanide systems. It adjusts the buffering capacity of the water independently of the sanitizer, helping maintain stable conditions that let your sanitizer perform effectively. Always follow sanitizer manufacturer guidance for combined treatments.

• Safe to use alongside chlorine and bromine sanitizers.
• Compatible with ozone and biguanide sanitizing systems.
• Helps create a stable environment for sanitizer efficiency.

How quickly will I see results and how often should I test?

Because the formula is granular and concentrated, results appear after the water has circulated and the product has fully dissolved—typically within a few hours. For best practice, test TA before treatment, again after full circulation, and routinely as part of weekly spa maintenance to keep levels within the recommended window.

• Expect measurable change after full circulation—usually hours.
• Retest after each adjustment to confirm target TA is reached.
• Include TA checks in your regular weekly maintenance routine.

Who is this for: Leisure Time Spa Up is designed for hot tub and spa owners, maintenance technicians, and property managers who need a dependable, easy-to-use product to raise and stabilize total alkalinity. It’s particularly useful when protecting spa surfaces, preventing corrosion or scale from pH volatility, and keeping water comfortable for bathers. Packaged as a convenient 2-pound size and sold in a two-pack, it’s a practical choice for residential and commercial spa upkeep.
