Pool & Spa Salt
Meet the AJ-PS40
Key Product Details
Why It Stands Out
Designed for Salt Chlorine Generator Systems
Generator-Compatible Formula
Specifically formulated for use with salt chlorine generators — helps maintain proper salinity levels that allow the generator to produce chlorine consistently and efficiently.
High-Purity Salt
Clean, high-purity salt composition minimizes residue and buildup — supporting generator cell efficiency and reducing the frequency of cell cleaning.
Smoother Water Feel
Properly maintained salinity levels help pool water feel softer and more comfortable on skin — a key benefit of saltwater pools over traditional chlorine systems.
Fast-Dissolving & Easy to Use
Fast-Dissolving Formula
Dissolves quickly in pool water when added directly — reducing wait times between application and when the pool can be tested and used again.
40 lb Bulk Supply
A large 40 lb bag provides a significant volume of salt for initial pool setup or routine salinity top-ups — reducing how often you need to restock during the season.
Routine Maintenance Ready
Suitable for both initial pool salting and ongoing top-up applications throughout the season — making it a reliable part of regular pool maintenance.
Where It Can Be Used
Salinity Reference Guide
Most salt chlorine generators operate within a specific salinity range. Always consult your generator manufacturer's manual for the exact recommended level for your system.
| Salinity Level (PPM) | Status | Action Required |
|---|---|---|
| Below 2,500 ppm | Too Low | Add salt — generator will not produce chlorine effectively at this level |
| 2,500 – 3,500 ppm | Optimal Range | Typical target range for most residential salt generators — no adjustment needed |
| Above 4,000 ppm | Too High | Do not add more salt — dilute by partially draining and refilling with fresh water |

What's in the Box
- 1 × 40 lb bag of Aqua Joe® AJ-PS40 Pool & Spa Salt
Usage Guide — Step by Step
Always test before adding · Add gradually · Retest after circulation
-
Test current salt level
Use a pool test kit or digital salt meter to check the current salinity level in your pool or spa. Do not add salt without first knowing the existing level — this prevents overshooting the target range.
-
Determine the correct amount to add
Based on your pool or spa volume, the current salinity reading, and your generator manufacturer's recommended target range, calculate how much salt is needed. Many generator manufacturers provide a salt calculator or chart in their manual.
-
Pour salt directly into the pool water
Add the measured amount of AJ-PS40 salt by pouring it directly into the pool — preferably in the shallow end or spread evenly around the perimeter. Do not pour salt directly into the skimmer or near the generator cell.
-
Run the filtration system
Turn on the pool pump and filter system to circulate the water. This helps the salt dissolve and distribute evenly throughout the pool. Run for at least 24 hours or as recommended by your generator manufacturer.
-
Retest salinity after circulation
After circulation is complete, retest the salinity level with your test kit or meter before adding any additional salt. Salinity does not change quickly — allow full circulation before determining whether more salt is needed.
Getting Started — Key Reminders
- Always confirm the customer has a salt chlorine generator-compatible system before recommending this product
- Add salt gradually based on test results — never add the full bag at once without testing first
- Run the pool pump during and after salt addition for proper dissolution and distribution
- Allow full circulation — typically 24 hours — before retesting and making further adjustments
- Remind customers that salinity changes slowly — patience between additions prevents overshooting the target range
Care & Storage
- Store in a cool, dry place away from moisture and direct sunlight
- Keep the bag sealed when not in use to prevent clumping from humidity
- Protect from prolonged moisture exposure — wet salt can harden and clump in the bag
- Keep away from children and pets — pool salt is not for consumption
- Do not store near pool chemicals that could react with salt (e.g., chlorine shock, acid)
Troubleshooting Guide
Possible Causes
- Salt not yet fully dissolved
- Insufficient pump/circulation time
- Incorrect pool volume estimate leading to under-application
Solutions
- Allow 24+ hours of pump circulation before retesting
- Retest with a calibrated salt meter — not just the generator display
- Recalculate required salt based on actual pool volume and current reading
Possible Causes
- Water chemistry imbalance — pH, alkalinity, or calcium hardness out of range
- Salt added before pool was properly balanced
Solutions
- Test all water chemistry parameters — pH, alkalinity, calcium hardness, and chlorine
- Rebalance water chemistry before retesting salinity
- Run filtration continuously until water clears
Possible Causes
- Salinity level still outside the generator's operating range
- Generator cell needs cleaning
- Sensor calibration issue
Solutions
- Verify salinity is within the manufacturer's recommended range
- Inspect and clean the generator cell if needed
- Calibrate the salt sensor per the generator manual
- Contact the generator manufacturer if issue persists after correct salinity is confirmed
Possible Causes
- Salt overapplication above the recommended range
- Insufficient circulation after adding salt
Solutions
- Always follow manufacturer salinity recommendations — do not exceed the target range
- Run the pump for full circulation after each salt addition
- If over-salted, partially drain and refill with fresh water to dilute
Possible Causes
- Pool volume unknown
- No salinity test performed before adding
Solutions
- Advise customer to test current salinity with a pool test kit or salt meter first
- Calculate pool volume (length × width × average depth × 7.5 for gallons)
- Refer to the generator manufacturer's salt chart or calculator for the correct amount to add
Possible Causes
- Bag exposed to humidity or moisture during storage
- Bag left open between uses
Solutions
- Break up clumps before use — product remains effective when dissolved
- Store in a sealed bag in a cool, dry location between uses
- Transfer to an airtight container for long-term storage
