AstralPool pool salt calculator

Use this AstralPool-focused pool salt calculator to estimate salt weight, bag count, and first-dose guidance from your current ppm and pool volume. The preset starts at 4000 ppm and remains editable for your exact model.

AstralPool target

AstralPool E Series guidance lists 4000 ppm as a recommended salt level, while older model manuals may vary by water temperature. Confirm the exact target for the installed unit. Treat the preset as a practical starting point, then use the exact target from your installed chlorinator documentation.

Not needed

Current salinity is not above the target.

Smart next steps

Large correction

Split the dose into two or more additions. Brush or circulate thoroughly before adding the remaining salt.

Buying salt

Buy whole bags, but add less than the full estimate first. Keep extra salt dry for the next maintenance cycle.

Safety reminder

Add only part of the calculated salt first, circulate the water, then retest. Pool equipment manuals and local water conditions should override generic estimates.

Why brand presets help

Different chlorine generator families can tolerate different practical salinity targets. A preset keeps the estimate aligned with the equipment family before you fine-tune the exact model value.

How to use it

Enter current salt, pool size, and salt purity, then retest after circulation before adding any remaining amount. Use the brand selector if your manual specifies a different target than the preset.
