Brand 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.
