SpaChoice Chlorine Granules for Hot Tubs 2-Pack (5 lb each) — Fast-Dissolving Spa Sanitizer, Controls Algae

SpaChoice 5-lbs 2-Pack Premium Spa Sanitizing Chlorules provides fast-dissolving chlorine granules formulated to sanitize hot tubs and spas, helping maintain clear water when used with proper testing and dosing.

Keeping spa water balanced and sanitary requires a dependable sanitizer and routine testing. SpaChoice chlorine granules dissolve quickly to deliver predictable available chlorine levels when added in measured amounts. Follow manufacturer guidance for circulation, dosing, and water testing to avoid overuse and to preserve spa equipment and components.

How do I start up a freshly filled spa with these granules?

Begin with the circulation system running and confirm proper flow. For initial treatment, add 6 teaspoons of the granules per 500 gallons of water, then test free available chlorine and repeat until chlorine reaches recommended startup levels.

• Turn on circulation before adding product.
• Add 6 teaspoons per 500 gallons as the initial dose.
• Retest free available chlorine and repeat if below target.
• Do not enter the spa if free chlorine exceeds 3 ppm.

How much chlorine will a teaspoon deliver and how often should I test?

Each level teaspoon (0.17 oz) yields roughly 1.4 ppm of available chlorine in 500 gallons of water. Frequent testing ensures pH, alkalinity and chlorine remain in recommended ranges for safe, comfortable use.

• 1 level teaspoon ≈ 1.4 ppm in 500 gallons.
• Target pH: 7.2–7.8; total alkalinity: 60–100 ppm.
• Maintain calcium hardness at or above 200 ppm.
• Use a reliable spa test kit before each use and after adjustments.

Can this product control algae and bacteria and how fast does it dissolve?

Yes — these granules are formulated to control algae and reduce bacteria presence as part of a regular sanitizer program. They dissolve rapidly and evenly when added to circulating water, helping achieve a consistent sanitizer concentration.

• Fast-dissolving granules for quick distribution in water.
• Part of a regimen to control algae and bacterial growth.
• Works when pools, pH, and alkalinity are properly balanced.
• Avoid mixing with incompatible chemicals or strong fragrances that may reduce effectiveness.

How often should I drain my spa and are there compatibility notes?

Drain intervals depend on use; SpaChoice recommends draining spas every 30–90 days and more often with heavy use. Always check your spa manufacturer's guidance to ensure the sanitizer is compatible with components and coverings.

• Recommended drain frequency: 30–90 days, or sooner with heavy use.
• Monitor cyanuric acid — do not exceed 150 ppm.
• Some oils, lotions, and cleaners can cause foaming or reduce sanitizer efficacy.
• Consult equipment manuals for compatibility advice.
