How does this spa salt support my hot tub’s salt system?

The salt provides a predictable, high‑purity sodium chloride source that feed salt chlorine generators and helps maintain sanitizer levels. Because it’s 99.9% pure with a medium grain size, it dissolves evenly and avoids gritty residue on spa surfaces and equipment.

• Feeds salt chlorine generators for steady sanitizer production
• Medium grain dissolves quickly to reduce settling
• No additives lowers the risk of scale and film
• Compatible with freshwater pools and spas sized up to ~500 gallons per bag

How do I add and dissolve this salt safely in my spa?

Add measured amounts to the circulating water with the pump running to encourage even distribution. For most systems, the 10 lb bag treats approximately 500 gallons; always follow your equipment manufacturer’s recommended target salinity and test after adding.

• Start with half the recommended dose, run the pump, then retest salinity
• Pour slowly near return jets to speed mixing
• Brush or agitate areas with visible residue while circulating
• Allow the salt to fully dissolve before retesting or entering the spa

Will this salt harm my spa equipment or my health?

Sea Salt Superstore’s spa salt is non‑toxic, BPA‑free, and gluten‑free, with no added anti‑caking agents or fragrances. Properly maintained systems and balanced water chemistry prevent corrosion and extend equipment life; always follow manufacturer maintenance and testing guidelines.

• 99.9% pure sodium chloride reduces unexpected deposits
• Free of additives that can affect seals or heaters
• Non‑toxic and safe for general spa use when used as directed
• Regular water testing prevents oversalting or imbalance

Can I use this salt for anything besides my hot tub?

Yes. The medium‑grain, pure salt also serves well as dishwasher salt and for freshwater pools that accept sodium chloride. Its clean composition and dissolvability make it versatile for several household and pool care applications.

• Dishwasher salt to improve softening and rinse results
• Supplemental salt for small freshwater pools compatible with NaCl
• Handy for emergency pool topping where purity matters
• Resealable 10 lb bag keeps salt dry between uses
