PoolLedger

Saturation index, dosing and a PDF service ticket.

What it does

PoolLedger works out your pool's volume, computes the Langelier Saturation Index, tells you how much of each product to add, keeps a history of every test and dose, and exports a service ticket as a PDF.

Common questions

Where does the chemistry come from?

The Langelier Saturation Index and the dosing arithmetic are published science, computed from your readings. Product strengths come from the product profiles you set up yourself.

Is this a substitute for a test kit?

No. Always confirm with a test kit, follow the product label, and never mix pool chemicals.
