About This Tool
Saltwater chlorine generators convert dissolved sodium chloride into free chlorine through electrolytic cells to sanitize pool water. Maintaining optimal salinity (typically 3,000 to 3,400 PPM, with 3,200 PPM as the standard operating target) ensures adequate chlorine production without triggering low-salt warning shutdowns or overloading cell electronics.
The dosage calculation uses pool water volume: pounds of pure salt required = (target PPM - current PPM) * pool gallons * 8.345 lbs/gal / 1,000,000. Dividing the total pounds by 40 and rounding up gives the number of standard 40-pound bags to purchase. For example, an 18,000-gallon pool testing at 1,200 PPM has a salinity deficit of 2,000 PPM to reach the 3,200 PPM target. The formula yields (2000 * 18000 * 8.345) / 1,000,000 = 300.4 pounds of salt, requiring 8 bags of 40-lb pool-grade salt (320 lbs total). All calculations execute client-side in your browser with zero remote storage.
How to Use
- 1
Enter your total pool water capacity in gallons.
- 2
Input your current measured salt concentration in PPM from test strips or an electronic meter.
- 3
Set your chlorinator cell target salinity level (default is 3,200 PPM).
- 4
Review the total pounds of salt and whole 40-lb bags needed to achieve target salinity.
Frequently Asked Questions
What happens if pool salinity drops too low?
When salt levels fall below the manufacturer threshold (often under 2,800 PPM), the chlorinator cell halts chlorine production to protect its catalytic coating, leaving water susceptible to algae.
How should pool salt bags be added to the water?
Broadcast salt bags evenly around the pool perimeter in the shallow end with the pump running, brushing thoroughly until dissolved before turning on the chlorine generator cell.
Are my swimming pool volume figures saved on any server?
No. All calculations run strictly inside your local web browser session.
