Pool Reading Measurements

What common pool logbook readings mean, how they are measured, and why units and measurement basis matter.

Using the Pool Volume Calculator

Measure sections, represent depth, resolve overlaps, and verify the volume before using it for pool operations.

Using the pH Up Calculator

Enter accurate readings, understand the dose and alkalinity estimates, and know when to stop and retest.

Using the pH Down Calculator

Match the acid product, understand the estimate and calculator limits, and follow safe handling requirements.

Using the Alkalinity Adjustment Calculator

Choose the labeled product, interpret the dry dose, and stage the total alkalinity correction.

Using the LSI Calculator

Interpret calcium carbonate saturation, CYA-adjusted alkalinity, status bands, and input checks.
