SpaChoice Chlorine Granules for Hot Tub — 5-Pound Fast-Dissolving Spa Sanitizer

SpaChoice 5-Pounds Premium Spa Sanitizing Chlorine Granules are a fast-dissolving chlorine sanitizer formulated to help keep hot tub and spa water clear and sanitized when used according to directions.

These chlorine granules are made for routine sanitization and initial start-up dosing of spa or hot tub water. They dissolve quickly to deliver available chlorine, helping manage microbes and algae when combined with proper water balance and regular testing. The product is intended for use in spas and hot tubs only and should be used with an accurate test kit to maintain recommended water chemistry.

How do I dose this product for a freshly filled spa?

For a newly filled spa, start circulation and add a measured initial dose to reach a safe starting free available chlorine level. SpaChoice recommends adding six level teaspoons per 500 gallons of water, then testing and repeating until free chlorine is in the suggested start range. Never allow people to enter the spa while chlorine levels exceed safe re-entry limits.

• Initial dose: 6 level teaspoons per 500 gallons of water
• Run circulation during and after application for even distribution
• Re-test free available chlorine (FAC) and repeat if FAC is still low
• Do not enter spa above 3 ppm chlorine for re-entry purposes

How much chlorine does each teaspoon add and how often should I test?

Each level teaspoon (about 0.17 ounces) provides roughly 1.4 ppm of available chlorine in 500 gallons of water. Because chlorine effectiveness depends on pH, alkalinity and organic load, frequent testing is essential—daily during heavy use and at least a few times weekly for typical residential use. Keep pH between 7.2 and 7.8 and total alkalinity around 60–100 ppm for consistent sanitizer performance.

• Per teaspoon: ~1.4 ppm available chlorine per 500 gallons
• Recommended pH: 7.2–7.8 for best chlorine activity
• Target total alkalinity: 60–100 ppm
• Test frequency: daily with heavy use, several times weekly otherwise

Will these granules work with my spa hardware and common additives?

SpaChoice chlorine granules are designed for spa and hot tub systems, but compatibility varies by manufacturer and accessory. Consult your equipment manual for sanitizer recommendations and avoid mixing incompatible chemicals. Oils, lotions, fragrances and some cleaners can reduce chlorine effectiveness or cause foaming, so minimize contaminants and follow any manufacturer guidance.

• Check spa manufacturer guidance for sanitizer compatibility
• Avoid adding fragranced products or oils near the spa to reduce foaming
• Do not exceed recommended cyanuric acid levels—keep below 150 ppm
• Drain and refill spas every 30–90 days depending on use

How do I use these granules safely and store them properly?

Handle granules with care: keep them dry, sealed, and stored away from children and pets. Use measuring spoons for accurate dosing and add granules to circulating water, not directly onto surfaces or into filter compartments. Observe label warnings and local regulations for pool and spa chemicals.

• Store sealed, dry, and out of reach of children and pets
• Measure doses precisely with a level teaspoon or calibrated scoop
• Add to circulating water and allow full dissolution
• Follow label instructions and safety precautions
