What does the pool salt calculator report?
It reports the pounds of pool salt needed and the approximate number of 40-lb bags based on your gallons, current salt ppm, and target salt ppm.

99.8 lb pool salt
Most salt bags are 40 lb. Let the pump circulate before trusting the cell reading.

How to use the dose
How to add pool salt
Test with a real salt meter, calculate the dose, spread it around the perimeter, and let it fully dissolve before retesting.
- Test salt with a real meterThe reading on your salt-cell controller is inferred, not measured — use a digital meter or test strip designed for salt.
- Calculate the doseUse this calculator with your gallons, current salt, and target salt for your generator's model.
- Walk the perimeter and brushPour slowly along the edge with the pump running, then brush the bottom to disperse any salt that piles up — never dump it all in one spot.
- Run the pump 24 hours and retestRun the pump 24 hours straight to fully dissolve the salt, then retest the next day.
Pro Take
You can do this yourself. Or you can stop chasing it.
If the cell keeps asking for salt after you add it, the issue may be the sensor, cell age, water temperature, or scaling. A&M services salt systems directly.

How to test
Get the reading before you dose
Use a salt strip, digital salt meter, or the salt-cell reading after the pump has circulated.
- Broadcast salt across the shallow end and brush until dissolved.
- Do not pour salt directly into the skimmer.
- Let the pump circulate before trusting the salt-cell reading.

Which target salt level should I enter?
Use the target from your salt chlorine generator manual or controller label. Many systems sit near 3,000 to 3,500 ppm, but the right number is equipment-specific.
Why should I wait before trusting the salt-cell reading?
Salt must dissolve and circulate evenly before the cell reading settles. Brush the salt, run the pump, and retest later so you do not accidentally add a second over-dose.
